Smart LiFePO4 charging
Protect your 48V lithium investment with the Epoch 48V 15A charger, a smart 48V lithium battery charger engineered for LiFePO4 systems in golf carts, RVs, marine setups, and off-grid battery banks.
This waterproof 48V charger combines standard 120V AC input, a 15 amp fast-charge output, ring terminal connections, up to 95% charging efficiency, and built-in safety protections in a rugged aluminum housing that is ready for mobile and onboard use.
The right charger protects your battery, improves performance, and helps preserve cycle life.
Standard lead-acid chargers are not designed around the voltage behavior of lithium iron phosphate chemistry. The Epoch 48V 15A LiFePO4 battery charger is built for 48V lithium systems, helping your deep cycle lithium charger deliver a safe, efficient charging cycle for compatible golf cart, marine, RV, and off-grid battery banks.
Designed for safe charging for LiFePO4 batteries, this smart lithium charger supports the charging needs of 48V lithium battery systems instead of relying on old lead-acid charging behavior.
The 15A output gives 48V golf carts, RV systems, marine lithium banks, and off-grid storage setups a practical balance of charging speed and battery-friendly current.
Built-in overcharge, overvoltage, overcurrent, reverse polarity, short-circuit, ambient temperature, and overtemperature protections help make charging simple and confidence-inspiring.
Built for mobile environments where dust, moisture, and vibration are part of the job.
The IP67 waterproof 48V charger uses a lightweight aluminum alloy body that doubles as a heatsink, helping it stay compact, durable, and efficient. Its shock-resistant design makes it a strong match for onboard golf cart charger installations, 48V marine lithium charging, RV charging compartments, utility vehicles, and shop or fleet maintenance use.
No 240V garage wiring required.
The Epoch 48V 15A charger plugs into standard 120V AC outlets and uses ring terminal output connectors for a secure battery connection. It is ready to charge right out of the box, making it easy to keep 48V lithium golf carts, RV battery systems, marine banks, and off-grid batteries topped up with less downtime.
A practical charger for golf cart, marine, RV, and off-grid lithium setups.

Better charging behavior for LiFePO4 chemistry.
LiFePO4 batteries require a different charging profile than lead-acid batteries. Pairing your 48V lithium bank with a dedicated smart lithium charger helps reduce the risk of incomplete charging, unnecessary BMS trips, and chemistry mismatch while delivering a simple plug-and-play charging experience.
Common questions about charger compatibility, safety, mounting, and charge time.
No. This charger is specifically programmed for 48V Lithium Iron Phosphate (LiFePO4) batteries. It should not be used on traditional lead-acid, SLA, AGM, or gel batteries because those chemistries require different charging profiles.
Yes. The Epoch 48V 15A charger is built with an IP67 dustproof and waterproof housing, a shock-resistant design, and ring terminal output leads, making it well suited for onboard golf cart, RV, and marine installations when installed according to the manufacturer’s guidance.
Charging time depends on your battery capacity and depth of discharge. To estimate, divide the battery’s amp-hour rating by the charger’s 15A output. For example, a fully depleted 48V 105Ah battery will take roughly 7 hours to recharge, with some additional time possible as the charger tapers near full charge.
No. This charger uses standard 120V AC input, so it can plug into a typical U.S. household wall outlet or a properly rated extension cord.
Yes. The Epoch 48V 15A smart lithium charger includes overcharge protection and other safety protections designed to prevent unsafe charging conditions. Always charge in a suitable location and follow Epoch’s charging and storage guidance.
The charger includes reverse polarity protection. If the output leads are connected incorrectly, the charger is designed to protect itself and the connected battery system rather than beginning a normal charge cycle.
No. This model is designed for 48V LiFePO4 battery systems. Use a dedicated 12V, 24V, or 36V LiFePO4 charger for lower-voltage lithium battery banks.
Before charging, verify that the connected battery is a compatible 48V LiFePO4 battery and confirm polarity, terminal security, cable routing, ventilation, charger mounting, and moisture exposure. Follow Epoch’s documentation and your battery manufacturer’s charging guidance for final installation and use.
