Description
When you need dependable, maintenance-free lithium power for your RV, marine system, solar bank, or off-grid setup without paying a premium for features you don't need, the Epoch 12100-ECO delivers 100Ah of proven LiFePO4 performance in a compact Group 24 footprint that installs where your old lead-acid battery lived.
- 4,500+ Cycle LiFePO4 Chemistry – Stable lithium iron phosphate chemistry delivers over 4,500 maintenance-free cycles, dramatically outlasting AGM and lead-acid alternatives in deep cycle applications at a fraction of the long-term cost.
- 100A Continuous Output with 300A Peak – Handles 100A of continuous discharge with a 300A peak for 5 seconds, backed by an advanced BMS that protects against overcharge, over-discharge, over-current, short circuit, and temperature extremes.
- Low-Temperature Charge Protection – Built-in BMS monitors cell temperature before allowing charge current, automatically blocking charging below the safe temperature range to protect cell integrity in cold weather.
- Group 24 Drop-In Footprint – Compact 10.25 x 6.75 x 9.00 in dimensions fit standard Group 24 battery trays in RVs, campers, marine applications, and 12V auxiliary systems without modification.
- Scalable Up to 4S16P Configuration – Connect up to 4 in series for 48V systems or up to 16 in parallel for expanded capacity, supporting battery banks as large as 1,600Ah and 81.92kWh at maximum configuration.
The 12100-ECO is purpose-built for practical 12V house power — RV and motorhome house banks, marine electronics, pumps, lighting, van builds, overland rigs, and solar storage for cabins and off-grid setups. At 1.28kWh of stored energy with 80% planning energy of approximately 1.02kWh, a single unit runs a 100W DC load for roughly 10 hours and a 500W load for about 2 hours under real-world conditions.
The ABS and PC blend UL94-V0 case with IP54 weather resistance handles everyday outdoor and marine exposure without concern, while the M8 bolt terminals provide a solid, low-resistance connection for high-current applications. There is no Bluetooth and no self-heating on this Eco Series model — keeping the price accessible while delivering the core LiFePO4 performance that matters most.
Certified to UL 1642 and UL 9540A cell standards, IEC 62619:2022, CE, and RoHS compliance, and shipped as UN 38.3 Class 9 lithium — this battery meets the requirements for residential, marine, and mobile installations and ships without restriction.
