Integrated Class T fuse
An Eaton Bussmann JJN-400 Class T fuse inside the case reduces fault energy at the battery outlet. Downstream protection is still required.
Victron CAN and app monitoring
Victron CAN at 500 kbit/s with DVCC on a GX device, and the Epoch Cloud app through the battery's State of Charge meter.
Internal heating
A 180.67W heater runs on charger power. Charging pauses at 32°F (0°C) and resumes at 41°F (5°C).

02 Safety
Safer chemistry, guarded by an advanced BMS
Lithium iron phosphate is the most thermally stable lithium chemistry, with a lower thermal-runaway risk than other lithium types. An advanced battery management system protects against overcharging, overdischarging, overcurrent and short circuits. UL Listed models are available, each with its certificate on its product page.
- 20+BMS safety protections
- LiFePO4The most thermally stable lithium chemistry
03 Performance
Built to outwork lead-acid
Compared with a lead-acid battery, Epoch LiFePO4 charges about 2.3 times faster, delivers twice the usable energy and weighs about half as much.
- 2.3xFaster charging than lead-acid
- 1/2About half the weight of lead-acid
Charge time
Epoch LiFePO4 About 3.5 h
Lead-acid About 8 h
Usable energy
Epoch LiFePO4 2x
Lead-acid 1x
Weight
Epoch LiFePO4 About 1/2

Bars illustrate published ratios against a typical lead-acid battery; they are not measurements of one model. 04 Longevity
Built for the long haul
Rated for thousands of charge cycles, up to about ten times the cycle life of lead-acid. Ratings vary by model; each model's datasheet gives the depth of discharge, charge rate, temperature and end-of-life capacity its rating was measured at.
- 15+Years design life
- Up to 10xThe cycle life of lead-acid; ratings vary by model
0Routine maintenance- No watering
- No equalizing
