Best Charger for LiFePO4 Batteries Buying Guide

I won’t bore you with the explanation of a LiFePO4 battery charger, but I will get straight to the point.

You need to consider a few factors while purchasing a lifepo4 battery charger. These are:

  • Voltage
  • Charging current

I will explain more about these crucial factors you need to consider in detail.

Voltage of the Battery

Is your battery 12V, 24V, or 48Volts?

Ideally, your battery should have a high voltage. Why is that you might ask?

Pricing of battery chargers depends on the current they will provide. Let me explain with an example.

A 12V charger delivering 10A has a charging power (watts) of 120W.

12V * 10A = 120W

The same 10A charger on a 48V battery can deliver 480W.

48V * 10A = 480W

The price of a 12V or 48V charger will be around the same at 10A. But the charging speed is 4 times faster!

To reduce the cost of your battery charger, increase your battery voltage.

Charging current

As I have already mentioned in the previous chapter, the current of the charger is what will determine its price.

But how much current should you charge your battery with?

LiFePO4 generally has a C-rate of 0.5C. This means that the maximum charging current should be multiplied by 0.5 and the battery capacity. Let me explain with a 12V 100Ah battery.

100Ah * 0.5C = 50A charging current

In this example, 50Amps is the max charging current. You can always go lower than this, but not higher.

There is no minimal charging current for a lifepo4 or lithium battery. If you drop the current, the charging time will be longer. Choose a low-current charger if you don’t mind the longer charging time. This will save you money.
