This charger is built specifically for 12-volt LiFePO4 (Lithium Iron Phosphate) batteries. It applies the correct charge profile for lithium chemistry, which differs from the profile used by lead-acid, AGM, and gel chargers. Using the wrong charger type on a LiFePO4 battery can shorten its lifespan or cause permanent cell damage over time.

Operation is straightforward. Plug the cord into any standard 120-volt AC wall outlet. Connect the ring terminals to your battery's positive and negative posts. The charger monitors the battery state, adjusts current as the battery fills, and shuts off automatically when charging is complete. No settings or adjustments are needed.

Typical uses for this charger:

• Anglers who run a 12V trolling motor on a bass boat, aluminum fishing boat, or pontoon and want a reliable overnight charge after a day on the water
• RV and travel trailer owners who return from a boondocking or dry-camping trip and need a dependable way to recharge their 12V lithium house battery from a standard outlet
• Boat owners running 12V house battery systems for lights, fish finders, and onboard electronics
• Off-grid cabin and solar storage setups that need a reliable AC backup charger when solar input is insufficient
• Van and overland vehicle owners with 12V lithium house battery banks

The aluminum alloy housing dissipates heat without a fan — the charger runs silently. It operates from -40 degrees Celsius to +60 degrees Celsius, covering cold-weather winter storage conditions and hot summer dock or campsite use. The IP67 rating means it is fully sealed against dust and can be submerged in up to one meter of water for 30 minutes — practical protection for a boat deck, RV storage bay, or outdoor use in rain.

Correct LiFePO4 Charge Profile
Designed for Lithium Iron Phosphate battery chemistry. Will not apply the high-voltage equalization pulses used by lead-acid chargers, which can cause irreversible damage to LiFePO4 cells.

Plug-and-Play Operation
Plugs into any standard 120V AC outlet. Ring terminal connectors attach to battery posts. No configuration or settings required — the charger manages the full charge cycle automatically.

Automatic Shutoff When Full
Overcharge protection stops charging when the battery reaches capacity. No damage from leaving it connected past full charge.

Reverse Polarity Protection
If the leads are accidentally connected to the wrong terminals, the charger will not operate. No sparks, no damage to the charger, no damage to the battery. Reconnect correctly and charging begins normally.

IP67 Waterproof and Dustproof
Fully sealed against dust and rated for submersion in one meter of water for 30 minutes. Suitable for marine environments, outdoor storage compartments, and use in rain or high-humidity conditions.

Aluminum Alloy Housing. Passive Cooling
The housing material dissipates heat without a fan. Silent operation. Lightweight and durable against vibration and impacts during transport and mobile use.

Shock-Resistant Construction
Rated for mobile environments including RV compartments subject to road vibration and boat hulls subject to wave movement.

Up to 95% Charging Efficiency
Less energy lost as heat during charging means faster charge times compared to less efficient chargers.

Wide Operating Temperature Range
Functions from -40°C to +60°C. Note: standard LiFePO4 batteries with basic BMS units will reject charging below 0°C to protect their cells. Epoch batteries with built-in self-heating will accept charging in sub-zero conditions.

Seven Protection Layers

• Reverse polarity protection
• Overcharge protection
• Over-temperature protection
• Ambient temperature protection
• Output overvoltage protection
• Output overcurrent protection
• Output short circuit protection

Estimated Charge Times by Battery Size

Estimates assume a low state of charge (approximately 10-15% remaining). Actual times vary based on starting charge level and ambient temperature.

For 300Ah batteries, Epoch's 50A charger will significantly reduce charge time. The 15A charger is well suited to batteries in the 50Ah to 200Ah range.
