E-FAST 12V 10A LiFePO4 Battery Charger — 14.6V Fast CC/CV, 0V Activation, Aluminum Housing

If you use high-capacity 12V lithium iron phosphate batteries in golf carts, RVs, marine craft, trolling motors or off-grid systems, you need a charger that matches their chemistry and duty cycle. This E-FAST unit provides a controlled CC/CV charge profile tuned to LiFePO4 cells, multiple safety cutoffs, and rugged hardware — including M8 terminals and a 50A Anderson connector — so you can connect quickly and run reliably under heavy or continuous loads.

How quickly will this charger refill a 12V LiFePO4 battery?

The charger supplies up to 10 amps at a 14.6V charge voltage, which significantly reduces fill time compared with lower-amp chargers. For example, a 100Ah 12V LiFePO4 pack can reach full charge in roughly 8–12 hours under ideal conditions; real-world times vary by battery state-of-charge and ambient temperature.

• Max output: 14.6V, 10A constant current/constant voltage profile
• Theoretical full-charge of 100Ah battery in ~10 hours under optimal conditions
• Works with 100–240V AC input, so it’s usable worldwide

What safety features protect my battery and charger?

E-FAST builds in a suite of protections to prevent common charging faults and extend component life. The charger shifts through CC/CV/float-cut modes and includes protections for over-voltage, short-circuit, and over-temperature conditions.

• Intelligent charge-stage transitions prevent overcharging
• Thermal management via an internal cooling fan and aluminum housing
• Short-circuit and over-voltage protection for both charger and battery

How do I connect this to my vehicle or battery bank?

Connection is flexible to match installation needs: heavy-duty M8 screw terminals give a permanent wiring option, while the included 50A Anderson connector supplies quick, tool-free hookups. The charger also supports 0V activation so it can revive deeply discharged batteries that other chargers won’t recognize.

• Dual connection options: M8 terminals and 50A Anderson plug
• 0V activation recharges deeply depleted LiFePO4 cells
• Clear LED: red while charging, green when fully charged

Will this charger hold up to frequent or continuous use?

The housing is premium aluminum for heat dissipation and durability, while an internal fan helps stabilize temperatures during extended charging sessions. These design choices reduce thermal stress and maintain charging performance when used in demanding situations like marina shore power or RV parks.

• Aluminum alloy housing for efficient heat transfer and longevity
• Active cooling fan to sustain performance under load
• Suitable for regular use with deep-cycle LiFePO4 battery banks

Who is this for: The E-FAST 12V 10A charger is aimed at owners of 12V LiFePO4 battery systems who need faster, chemistry-specific charging and robust connection options. It’s a solid choice for golfers and fleet operators with large battery banks, RV and marine enthusiasts who want reliable shore-power charging, and off-grid solar users requiring dependable, temperature-managed charging. If you want a dedicated LiFePO4 charger with 0V activation, clear LED status, and both permanent and quick-disconnect connections, this unit offers that capability in a durable, compact package.
