The Epoch 12V 50A Lithium Battery Charger is a high-output smart charger for large 12V LiFePO4 house banks in RVs, boats, vans, and off-grid systems. Its 50A output recovers big lithium banks far faster than small 10A or 15A chargers, helping cut generator runtime and get you back to camp or on the water sooner.
It runs from standard 120V AC shore power or a suitably sized generator, connects with heavy-duty ring terminals, and operates at up to 95% efficiency. The IP67 aluminum housing doubles as a heatsink and resists the vibration of mobile installations.
Key Features
-
Dedicated LiFePO4 profile: Built specifically for 12V lithium iron phosphate batteries rather than lead-acid charging routines.
-
50A charge output: Adds up to about 50Ah per hour in bulk; a 200Ah bank charges in about 4 hours and a 460Ah bank in about 9.2 hours.
-
Plug-and-play setup: Plugs into a standard 120V AC outlet and connects to the battery with secure ring terminals.
-
IP67 waterproof: Fully sealed against dust and water with a shock-resistant design for RV, marine, and mobile use.
-
Aluminum heatsink housing: The lightweight aluminum alloy body doubles as a heatsink for efficient thermal management.
-
Wide working range: Rated for working temperatures from -40°C to 60°C (-40°F to 140°F).
-
Full protection suite: Guards against overcharge, reverse polarity, output overvoltage, overcurrent, short circuit, and ambient and internal overtemperature.
-
Generator friendly: Works from a portable generator that supplies stable 120V AC, reducing runtime when boondocking.
Charging Time Estimates
- Estimate: battery amp-hours ÷ 50A.
- 100Ah: approx. 2 hours
- 200Ah: approx. 4 hours
- 300Ah: approx. 6 hours
- 460Ah: approx. 9.2 hours
- Actual time varies with state of charge, temperature, BMS limits, wiring, tapering, and bank configuration.
Suitable For:
- RV and camper lithium house batteries
- Marine house banks for boats, pontoons, and fishing rigs
- Boondocking generator charging
- Shore power at marinas, campsites, and RV parks
- Van life, overland, and mobile 12V LiFePO4 systems
- Large-capacity 12V backup and off-grid banks
Please Note: For 12V LiFePO4 batteries only. Do not use on AGM, flooded lead-acid, gel, SLA, or automotive starting batteries.
Please Note: Only use with batteries or banks rated to accept at least 50A of charge current.
Please Note: A dedicated 0V BMS wake-up function is not published for this charger; follow the battery manual or contact Epoch support before recovering a battery that reads 0V.
Please Note: For multi-battery banks, verify cable sizing, fuse protection, ventilation, and charge-current limits.
