About the 12V 100ah EPOCH Eco Series LifePO4 Lithium Battery

The EPOCH Eco Series is a 12V 100Ah deep cycle battery that uses LiFePO4 (lithium iron phosphate) chemistry. It comes in a compact Group 24 size and weighs about 21 lb. It is designed as a drop-in replacement for a standard lead-acid Group 24 battery.

A built-in battery management system (BMS) provides 20+ safety protections, including over-charge, over-discharge, short-circuit and temperature cut-offs. Charging cuts off at 0 °C (32 °F). The battery discharges down to -20 °C (-4 °F) and is weather rated for marine use. It needs no watering or acid top-ups.

Up to 4 batteries can be connected in series for a 48 V system. Up to 16 can be connected in parallel for 20.48 kWh of storage. Uses include marine trolling motor banks and electronics, RV and van power, solar and off-grid storage, and backup power.

Questions and answers

How does this compare to a lead-acid battery?
It weighs about a third as much, delivers more usable capacity, and lasts thousands more cycles. It also has built-in protection that lead-acid lacks.
Can I use it in cold weather?
Yes, for discharge down to -20°C, but charging is cut off at 0°C to protect the cells. You need to warm it above freezing before charging.
What can I power with one battery?
One 12V 100Ah unit provides 1,280 Wh, enough for modest RV or boat loads, trolling motors, or small solar setups. For larger needs, connect several in parallel.
Does it have Bluetooth or a monitor?
No, this model does not include Bluetooth or a built-in monitor. You would need an external battery monitor to track state of charge.
Is it safe to mount in any orientation?
LiFePO4 batteries like this one can be mounted in most orientations because they don't contain liquid electrolyte. However, check the manufacturer's guidelines for specific restrictions.
