## Description

At 8.3 inches wide, with a 2.6-inch depth and 3.5-inch height, the E-FAST TK-2500 pairs a compact footprint with an aluminum housing. This 12V LiFePO4 charger delivers 14.6V charging voltage and up to 20A, giving owners of golf carts, RVs, boats, and other listed applications a dedicated charger for lithium iron phosphate batteries.

Its 0V activation feature is designed to help reactivate depleted batteries. Need a charger focused on LiFePO4 rather than a general-purpose unit? The TK-2500 also offers M8 and Anderson connection options for practical battery hookup.

## Product specs

- Type: 12V LiFePO4 battery charger
- Charging voltage: 14.6V
- Current: Up to 20A
- Activation: 0V activation for depleted batteries
- Housing: Aluminum alloy
- Connections: M8 and Anderson
- Dimensions: 2.6" D x 8.3" W x 3.5" H

The charger is designed specifically for 12V lithium iron phosphate batteries. Its charging control transitions through CC/CV/float cut-off modes, while over-voltage, short-circuit, and over-temperature protections support controlled operation. These features make it suited to routine charging of a compatible battery in a golf cart, RV, marine setup, boat, or trolling motor. The 20A output is also relevant when choosing between this and a lower-current charger: it offers a higher stated current for charging a compatible battery bank.

## Practical tips

Match the charger to a 12V LiFePO4 battery, and select the connection that fits the battery terminals: M8 or Anderson. The built-in cooling fan supports heat management during operation, and the aluminum housing forms part of the charger’s physical design. For status at a glance, the LED is red while charging and green when fully charged. Place the charger where its fan can operate during use, and follow the battery maker’s charging guidance.

Buyers commonly describe the charger as working well and charging 100Ah batteries quickly. Feedback about fan noise is mixed: some find it unobtrusive, while others notice it. That perspective can help when deciding where to use the charger, particularly in a quiet indoor area.

## Box contents

An Anderson connector is included, providing a ready connection option for setups that use this connector. The charger also supports M8 connections, giving owners another way to match the charging lead to the battery terminals.

## Questions before you buy

**What battery chemistry is this charger designed for?** It is made for 12V lithium iron phosphate (LiFePO4) batteries, with a charging voltage of 14.6V. Choose it for that battery type rather than treating it as a universal charger for other chemistries.

**Can it help with a depleted battery?** The charger includes 0V activation, a feature intended to reactivate depleted batteries. Use it with a compatible 12V LiFePO4 battery.

**How can I tell when charging is complete?** The dual-state LED shows red during charging and green when the battery is fully charged.

## When it makes sense

The E-FAST TK-2500 is a practical match for owners who need a dedicated 12V LiFePO4 charger for a golf cart, RV, boat, marine application, or trolling motor. Its 20A output, 0V activation, two connection options, and clear LED status make it especially useful when the priority is a purpose-built charging setup for compatible lithium batteries.
