## Description

Chargers designed for lithium batteries, from 12 V LiFePO4 to 48 V systems. Match the voltage and buy online.

## Why lithium needs its own charger

Lithium batteries, and LiFePO4 in particular, need a precise charge profile: constant current followed by constant voltage at the right final value, with no equalisation or desulphation phases. Lead-acid chargers can undercharge them or apply modes that are not suitable. This section offers 7 chargers designed for lithium:
- **Kronobat 10AMP 14.6V** and **30AMP 14.6V:** for 12.8 V LiFePO4 batteries, at 10 or 30 A.
- **Fulbat FLC-25.6-30:** for 25.6 V (24 V class) lithium batteries.
- **Fulbat FLC35.2-25:** for 35.2 V packs.
- **Fulbat FLC48-20** and **FLC48-25:** for 48 V systems.
- **Fulbat FLC-51.2-20:** for 51.2 V LiFePO4 packs, at 20 A.

## How to choose

First, match the nominal voltage of your battery exactly. Then choose the current: as a guide, a charger delivering about 10–30 % of the capacity in amps gives a reasonable charging time. For 12 V leisure batteries see [12 V LiFePO4 lithium batteries](https://bateriasonline.es/en/lifepo4-lithium-batteries-12v); for other chargers, the full [battery chargers](https://bateriasonline.es/en/battery-chargers) section or the [Fulbat batteries](https://bateriasonline.es/en/fulbat-batteries) range.

## Frequently asked questions

### Can I charge a lead-acid battery with these chargers?

No, they are set for lithium profiles. Use a lead-acid or multi-chemistry charger instead.

### Which charger for a 100 Ah LiFePO4?

The Kronobat 14.6 V models suit 12.8 V batteries; the 30 A version charges a 100 Ah battery faster than the 10 A one.
