Epoch Eco Series LiFePO4 Batteries (12V)
Free shipping over $49
Lithium batteries & products containing lithium batteries are non returnable
The Epoch Eco Series is the value entry point into LiFePO4 — a clean, reliable 12V deep-cycle battery for RVs, vans, trolling setups, and off-grid systems where you want the weight savings and long life of lithium without paying for heating or Bluetooth. It's a simple drop-in upgrade from lead-acid, with a smart BMS handling protection and a very long cycle life for the price.
Available as a Group 24-style 12V 100Ah and a high-capacity 12V 314Ah, both ready to scale in series and parallel.
Key Features
- LiFePO4 deep-cycle — light, maintenance-free, and far longer-lived than lead-acid.
- Smart BMS — over-charge, over-discharge, over-current, short-circuit, and temperature protection.
- Expandable — up to 4 in series (to 48V) and 16 in parallel to build larger banks.
- Long cycle life — 4,500+ cycles on the 100Ah and 8,000+ cycles on the 314Ah.
- Value-focused — no heating or Bluetooth, keeping cost down for moderate-climate and budget builds.
