A 52V eBike battery is a 14S Li-ion pack and requires a 58.8V charger. Using a 54.6V (48V) charger will under-charge it. This guide covers compatibility, connectors and finding the right 52V charger.
Why 58.8V?
14 cells × 4.2V max = 58.8V. The charger must reach this to fully charge a 52V pack.
Connectors for 52V Packs
Most 52V chargers use DC barrel, XLR or Rosenberger. Match the port on your battery; we supply all three.

Frequently Asked Questions
Can I charge a 52V battery with a 48V charger?
Not fully — a 54.6V (48V) charger stops short of a 52V pack’s 58.8V requirement. Use a 58.8V charger.
Is 52V the same as 48V?
No. 52V (14S) sits between 48V (13S) and 60V (16S). It needs its own 58.8V charger.
What current should I choose?
2A is standard; 3–4A for faster charging if the BMS allows.
