A trolling motor battery box has to do more than hold a battery. It needs to contain moisture, resist movement, provide secure cable connections, and fit the limited space available in a kayak, small boat, or fishing platform.
The seven options below cover different needs, from compact Group 31 lithium batteries to full marine enclosures with fusing, USB charging, and integrated displays. Five are battery enclosures, while two are mounting trays designed for smaller batteries. Matching the case to the battery’s dimensions, chemistry, and electrical output matters more than appearance.

What Each Pick Brings To The Table
Large energy reserves rarely fit neatly into an RV compartment, but this Redodo model combines 320Ah capacity with a housing described as 32% smaller than standard 300Ah batteries. That makes it worth considering for Class A, B, or C motorhomes, travel trailers, fifth wheels, and truck campers that need substantial off-grid power without surrendering storage space.
Bluetooth monitoring adds useful visibility, although this is a battery rather than a complete trolling motor enclosure. Boaters needing spill containment, terminals, fusing, and marine wiring gain more from the Voltage V55-PF later in the list.
What It Does Well
- The 4,096Wh capacity supports larger onboard systems and extended periods away from shore power.
- A reduced footprint preserves storage for camping gear and other travel essentials.
- Bluetooth connectivity supports remote battery status checks.
- LiFePO4 chemistry suits repeated deep-cycle applications better than a basic starter battery.
Practical Considerations
- Weight and securement planning are essential in a moving RV.
- The listing includes protection and support details, so check the current coverage terms before purchase.
Feature Facts
Built With In Mind
You benefit most with a space-constrained RV carrying several high-draw appliances.
Another Choice May Suit
The VMAX Group 24 Smart Battery Box Power Center suits boat owners who need enclosure features and USB charging rather than 320Ah of battery capacity.
The Group 31 format makes this 100Ah battery a familiar middle ground for marine electrical upgrades. It offers enough deep-cycle capacity for many trolling motor, fishing electronics, and cabin accessory loads without moving into the heavier 165Ah or 320Ah configurations.
For anglers who favor a simpler installation, its low stated self-discharge can reduce maintenance between outings. The catch is that this remains a bare battery, so you still need a suitably sized enclosure and a protection plan matched to the trolling motor’s current draw.
A Favorable Mix
- Group 31 dimensions simplify comparisons with common marine battery compartments.
- The stated 3% self-discharge supports storage during intermittent use.
- A quoted 4,000-cycle figure at full depth of discharge supports frequent charging use.
- Bluetooth connectivity is available for monitoring on this listing.
Trade Offs
- No enclosure, terminals, or fusing are included with the battery.
- Long cycle figures depend heavily on charge management, temperature, and operating depth.
The Numbers That Matter
Made For
Recreational anglers need a balanced battery for moderate trolling loads and onboard electronics.
Look Elsewhere When
The Redodo 320Ah Mini LiFePO4 Bluetooth Battery better serves RV owners needing much greater stored energy.
Bluetooth 5.0 monitoring distinguishes this Group 31 battery from the more basic Redodo 100Ah option. Through the Redodo app, you can review voltage, current, and capacity, then remotely shut down the battery, which is useful during a long fishing day away from the launch.
A charging cut-off below 0°C adds another layer of cold-weather control, although owners should verify the complete operating limits before winter use. As with the previous Redodo pick, this is a battery, not a waterproof enclosure for a trolling motor installation.
Benefits That Matter
- Real-time electrical readings make battery status easier to check remotely.
- Remote power control helps isolate the battery when troubleshooting.
- Low-temperature charging protection reduces charging below freezing.
- Group 31 sizing fits many conventional marine and RV installations.
Worth Noting
- App visibility adds another item to maintain and configure.
- The enclosure still needs compatible terminals, fusing, ventilation, and secure mounting.
Who Will Love This
You gain the most control with a Group 31 installation where remote monitoring offsets the extra setup.
A Better Fit Elsewhere
The Redodo 100Ah LiFePO4 Group 31 Battery is the simpler option for owners who don’t rely on app-based control.
This is the most purpose-built enclosure in the group for a trolling motor battery. The V55-PF accepts 12V 50Ah lithium or AGM batteries and 12V 55Ah sealed lead batteries, making it a practical choice for kayak anglers, small boats, and solar backup systems exposed to spray and shifting cargo.
Unlike the Redodo batteries, it includes external stainless steel posts, marine-grade 8 AWG wiring, and a fuse holder with a 60A maxi fuse. A pressure-release valve handles internal pressure changes, although correct assembly remains central to effective sealing.
A Strong Showing
- The IP67 enclosure targets protection from dust and temporary immersion.
- Stainless steel posts suit damp marine environments.
- The integrated 60A fuse provides a defined electrical protection point.
- Preassembled marine wiring reduces the number of connections you must build.
Details To Watch
- The case fits only specific battery sizes, so measure terminals and case height first.
- Owners should inspect seals, cable strain relief, and fasteners during routine maintenance.
Technical Reference
Right Fit For
Small-boat owners benefit most from a sealed, wired enclosure sized for a 50Ah or 55Ah battery.
Where A Sibling Pick Shines
The VMAX Group 24 Smart Battery Box Power Center better serves Group 24 battery owners wanting USB ports and an LED voltage display.
The VMAX enclosure turns a Group 24 battery into a more accessible onboard power center. Its LED display gives you a quick voltage reference, while two USB-C ports and a QC3.0 USB-A port support phones, navigation equipment, and other USB-powered accessories.
Group 24 compatibility includes AGM, gel, and LiFePO4 batteries, giving you more chemistry flexibility than a case built around one case dimension. Compared with the Elephant Cases V55-PF, it adds charging convenience but does not present the same explicit IP67 sealing specification in the supplied information.
A Few Highlights
- The display provides a fast visual check of battery voltage.
- Dual USB-C ports simplify charging newer devices.
- QC3.0 USB-A output adds a second charging standard.
- The enclosure supports AGM, gel, and lithium battery formats.
Small Caveats
- USB output is not a substitute for correctly sized marine power wiring.
- The enclosure only accommodates Group 24 dimensions.
- Keep USB ports covered and dry during rough conditions.
Essential Details
Who It Suits Best
Boat owners benefit most when their Group 24 installation also powers USB devices away from a shore outlet.
Reach For A Different Pick When
The Elephant Cases V55-PF Waterproof Battery Box is a stronger match for a sealed 50Ah or 55Ah installation with an explicit IP67 enclosure rating.
This battery concentrates 2,112Wh into the same broad Group 31 case family used by the earlier 100Ah Redodo models. That higher capacity makes it relevant to anglers running demanding electronics alongside a trolling motor, especially on long days far from a launch point.
The stated 165A battery management system supports high-current discharge, but your trolling motor, wiring, and fusing still need to be sized consistently. You also gain Bluetooth visibility without receiving a waterproof trolling motor case, so plan the enclosure separately.
Notable Gains
- The 2,112Wh rating supports longer trips between charging opportunities.
- A 165A battery management system accommodates substantial discharge demand.
- Bluetooth adds remote operating-state visibility.
- Group 31 packaging avoids moving to a much larger case category.
Practical Considerations
- Additional capacity can increase weight and mounting demands.
- Your charger and wiring must support the battery’s operating specifications.
Built For Long Days
Offshore anglers benefit most from the longer runtime needed for sustained trolling and accessory loads.
Swap It Out When
The Redodo 100Ah LiFePO4 Group 31 Battery offers a lighter fit for shorter outings with lighter electrical demand.
These trays serve a narrower purpose than the larger marine cases: holding smaller 12V or 6V batteries securely during transport. Each aluminum tray uses an adjustable strap, making a simple installation plausible for a kayak, canoe, jet ski, small boat, or portable generator.
The 5052 aluminum construction resists marine corrosion while keeping the 4-ounce tray light. You can mount the battery horizontally or vertically, depending on the craft, but this remains an open tray rather than a sealed enclosure for a large trolling motor battery.
Strengths Worth Knowing
- The two trays support separate batteries or give you a spare.
- Predrilled mounting slots simplify attachment to different equipment.
- The adjustable strap limits rolling and movement.
- Vertical or horizontal mounting accommodates varied compartments.
Less-Strong Areas
- The open design does not provide sealed protection from splashes.
- Fitment centers on 12V 6Ah to 15Ah or 6V 7Ah to 12Ah batteries.
- Regularly check strap tension and mounting-slot corrosion.
Core Details
The Right Fit
Portable-craft users benefit most from a lightweight tray for a small battery that doesn’t require sealed containment.
Look Elsewhere When
The Voltage V55-PF Waterproof Battery Box suits owners of a larger 50Ah or 55Ah trolling motor battery needing a sealed enclosure and marine wiring.
Choosing The Right Battery Housing
Start With The Battery Format
Group 31, Group 24, and compact marine batteries have different dimensions and terminal layouts. Measure the compartment, cable bend radius, and terminal clearance before choosing. A battery that fits physically may still leave no room for secure mounting or a properly supported lid.
Decide Between Battery And Enclosure
Several choices on this list are batteries rather than boxes. The Redodo models supply stored energy and Bluetooth monitoring, while the VMAX and Elephant Cases products provide housing functions. Your setup may require both categories rather than one item doing every job.
Match Protection To The Environment
IP67 protection, as specified for the Voltage V55-PF, targets dust and temporary immersion. Open aluminum trays suit smaller batteries where weight and compact storage matter more. Saltwater, spray, and rough transport call for sealed components, corrosion-resistant hardware, and secure lids.
Size The Entire Electrical System
Trolling motors can draw substantial current during acceleration. Battery capacity, cable gauge, terminals, fuse rating, and charger output must operate as a matched system. A larger amp-hour rating increases potential runtime, but it can also add weight that reduces portability.
Practical Checks Before Installation
Mistakes Worth Dodging
Choose by battery case size rather than amp-hour rating alone. Group numbers describe physical formats, not output capacity, and an enclosure must also clear its terminals and cable exits.
Never assume an open tray is waterproof. Plan the fuse placement, cable routing, strap tension, and corrosion treatment before taking a battery onto the water.
Where The Extra Spend Goes
Advanced enclosures add features such as sealed construction, integrated wiring, pressure valves, displays, and USB charging. Those additions suit boats needing monitoring and protected connections.
A basic tray can make more sense for small batteries in a clean, sheltered craft. Pay for added construction only when your environment and accessory loads create a genuine need.
Frequently Asked Questions
Are LiFePO4 batteries suitable for trolling motors?
Yes, LiFePO4 chemistry works well for repeatable deep-cycle use. You still need a charger, enclosure, and wiring rated for the battery and motor load.
Is a Group 31 battery box universal?
No, Group 31 describes a case format, not universal electrical compatibility. Confirm dimensions, terminal placement, required amp-hour capacity, and the trolling motor’s current draw.
Does a waterproof battery box stop all corrosion?
No. A sealed enclosure reduces exposure, but saltwater residue still requires periodic cleaning and inspection. Check terminals, seals, fasteners, and mounting hardware after heavy use.
Should a trolling motor battery box include a fuse?
A properly sized fuse is an important circuit-protection feature. Its rating and placement must match the battery, cables, motor controls, and connected equipment.
Can you use a small aluminum tray for a trolling motor battery?
Only within its stated capacity range and with secure mounting. Larger trolling motor batteries require an appropriately sized case and a system designed for their weight and current draw.
Final Verdict
Choose the Voltage V55-PF for a sealed 50Ah or 55Ah installation, or the VMAX for a Group 24 setup with convenient USB charging. The Cococheers trays work best for compact portable batteries, while the Redodo choices provide the battery capacity and Bluetooth monitoring your motor system may need. Match dimensions and electrical specifications before deciding.
