EV Charger Buying Guide
Everything You Need to Know
The wrong charger shortens the life of a battery. Keep this in mind:
Voltage match
A 48V charger for a 48V battery - never use a charger with a higher voltage.
Current (Amp)
A current of 10-20% of the battery capacity works well. For a 100Ah battery, a 10A-20A charger.
Auto cut-off
A smart charger switches off by itself once the battery is full - so the battery is not overcharged.
Warranty
Always buy a charger with a warranty; a cheap local charger ruins the battery.
