- Epoch is the brand of Epoch Batteries LLC of Marietta, Georgia, a veteran-owned company that its store says was founded in 2019.
- The EPOCH BATTERIES trademark for batteries is owned by EDG Sales International LLC of Stockbridge, Georgia, named as manufacturer on an Epoch UN38.3 test summary.
It sells with a cart at epochbatteries.com and through authorized dealers such as Current Connected, Blue Marine and Citimarine, after announcing a dealer-only switch for July 2025.
The Epoch 48V 100Ah V2 Elite (model C48100A) is a 51.2 V, 100 Ah LiFePO4 battery storing 5,120 Wh (5.12 kWh) in 16 series prismatic cells. Epoch rates it at 150 A maximum continuous discharge for up to 20 minutes and not for cycling, 300 A for 30 seconds, and 100 A continuous charge with 300 A for 5 seconds.
The BMS trips at 110 A charge or 350 A discharge after 5 seconds, short-circuit protection acts at 1,200 A, and a 270 A internal fuse (UL 60691) sits inside the case. A heater powered by the charge source warms the cells before charging, which is supported from −30 °C (−22 °F) ambient; discharge runs from −20 to 55 °C.
Bluetooth 4.0 runs through the included battery gauge to the Epoch Li-Ion app, and CAN at 500 kbit/s links it to a Victron GX device with DVCC. Banks run up to 16 in parallel (1,600 Ah, 81.92 kWh); Epoch says never to connect it in series.
The IP67 case measures 20.86 x 8.65 x 12.06 in (529.8 x 219.8 x 306.3 mm) with the terminal posts, weighs 97 lb (about 44 kg), has M8 terminals 17.99 in apart and six M8 nuts for the optional 8D bracket. In the box are the mountable gauge, a mountable on/off switch and the Victron communication harness.
Epoch rates it for 3,500 or more cycles to 70 percent remaining capacity at 25 °C and gives it an 11-year limited warranty with registration within 90 days. The V2-T Elite version with an integrated 250 A Eaton Class T fuse (C48100A-A), which the store files as a Victron marine battery, is $2,599 on its own page.
