Group 24 Drop-In 100Ah 12V LiFePO4 Camper House Battery 1280Wh Compact Tray 100A BMS

Group 24 Drop-In 100Ah 12V LiFePO4 Camper House Battery 1280Wh Compact Tray 100A BMS

This 12.8V 100Ah LiFePO4 battery is built for campers and boat owners who want lithium performance without redesigning their battery compartment. Its case follows the standard Group 24 footprint, so it slides into the same tray that once held an AGM or flooded battery and connects with the existing ring terminals in minutes.

Inside the compact housing sit Grade-A LiFePO4 cells that deliver 1280Wh of usable energy - about twice what a 100Ah lead-acid battery can safely provide - while cutting weight from roughly 24kg down to 10.8kg. A 100A smart BMS watches over every cell and handles the protection duties that keep the pack safe in daily RV service.

Compact Group 24 Footprint
The external size matches BCI Group 24 dimensions at 260 by 173 by 225 millimeters, which means no tray fabrication, no adapter brackets and no rewiring when you retire an old battery. The top-mounted M8 studs accept standard automotive ring terminals, and the reinforced case handles the vibration of highway travel without flexing. For pickup campers, teardrop trailers and small center-console boats where every centimeter counts, this footprint keeps installation straightforward.

1280Wh of Honest Usable Energy
A lead-acid Group 24 battery is rated at roughly 80Ah, but discharging it below 50% ruins its lifespan, leaving only 480Wh of practical energy. This lithium pack delivers its full 100Ah and 1280Wh on every cycle. In real terms that runs a 12V compressor fridge for a full day, keeps LED lighting and a water pump going through a long weekend, or powers a 500W inverter for laptops, camera chargers and a small TV well into the evening.

100A Smart BMS Protection
The 100A continuous BMS matches the discharge appetite of common 12V loads while leaving headroom for brief surges up to 200A when an inverter or motor starts. The BMS continuously balances cell voltages during charging, which keeps the pack performing evenly for thousands of cycles. Over-voltage, under-voltage, over-current, short-circuit and high-temperature conditions all trigger automatic disconnects, and a low-temperature charge cutoff prevents charging below 0 deg C.

Grade-A Cells with 4000 Cycles
Each cell is sourced from a tier-one lithium factory and matched for capacity and internal resistance before assembly, so the pack delivers the rated 100Ah from the first day. At 80% depth of discharge the battery is rated for 4000 cycles, which translates to more than a decade of weekend camping or roughly ten times the service life of a comparable AGM battery. Even at the end of that life it still holds 80% of its original capacity.

Why This Battery Beats an Equivalent AGM
Compare like for like: a 100Ah AGM Group 24 battery weighs about 24kg, delivers roughly 480Wh of usable energy and survives 500 cycles at best. This LiFePO4 pack weighs 10.8kg, delivers 1280Wh usable and is rated for 4000 cycles. Over ten years the AGM route means buying three or four replacement batteries, while one lithium pack keeps working. Charging behavior differs too: AGM acceptance current tapers as the battery fills, while lithium accepts the full charge current until it reaches 14.6V, so solar and alternator charging finish faster and waste less engine time.

Where This Battery Fits Best
The sweet spot for this pack is the weekend camper, the teardrop trailer, the small sailboat and the utility trailer with a winch. It also works well as a starter-house dual battery in trucks, or as a second house bank for RVs that already run a large lithium pack and need extra capacity in a different compartment. Pair it with 100 to 200W of solar and a small MPPT controller, and the battery becomes a self-sustaining power source for boondocking trips that last several days.

Light Enough to Carry
Weight is where lithium separates from lead. At 10.8kg this battery is less than half the weight of the Group 24 AGM it replaces, and about a third of a flooded equivalent. That saving matters for tongue weight on trailers, for slide-in camper payload limits, and for anyone who has ever wrestled a battery out of a tight compartment at the end of a season. Two people can lift it with one hand each, and no special handling equipment is needed.

Silent, Fume-Free and Indoor-Safe
LiFePO4 chemistry does not vent hydrogen or corrosive acid vapor during charging, so this battery can be installed inside the living space, under a dinette seat or in an unvented compartment. There is nothing to spill and nothing to corrode, which also protects the surrounding steel and wiring from the acid mist that slowly destroys lead-acid compartments. The flame-retardant ABS case adds another layer of safety.

OEM and Private Label Service
As a factory-direct product from the WNRLN brand, this battery is available with custom labels, custom packaging and tailored BMS parameters for camper builders and marine distributors. We share full datasheets, test reports and compliance documents to support your own product launches, and our engineers help match the right cell configuration to your target price point.

Frequently Asked Questions

Q: Can I use this battery to start my engine?

A: This is a deep-cycle house battery, not a starter battery. It can support moderate cranking in a pinch, but for engine starting we recommend a dedicated starting battery or one of our dual-purpose models. Use it to run your fridge, lights, pumps and inverter loads instead.

Q: Will my existing solar charge controller work with it?

A: Yes, as long as the controller has a LiFePO4 or user-defined profile. Set the absorption voltage to 14.6V and float to 13.8V. Many modern MPPT controllers from Victron, Renogy and EPEver include a lithium preset that matches these values.

Q: How do I know when it is fully charged?

A: The BMS balances cells and the voltage settles at 13.2-13.4V at rest after a full charge. For precise state of charge, add a shunt-based battery monitor or a Bluetooth BMS version. A simple voltmeter reading of 13.3V at rest indicates roughly a full pack.

Q: Can I connect two of these in parallel for more capacity?

A: Yes. Up to four 100Ah packs can be paralleled to create a 400Ah / 5120Wh bank. Each pack has its own BMS, and parallel packs share current naturally. Use equal-length cables to a common busbar and fit one fuse per pack at the positive terminal.
