Why choose this pack?

Many aftermarket batteries lack proper BMS communication, causing error codes or charger rejection. Our pack mirrors original NIU firmware handshake, so you get full display readout (estimated range, battery percent) and proper charging cut-off. Cells come from A-grade suppliers with UL/CE certification – not rebuilt or used cells.

Package includes:

1x 48V battery pack (40Ah or 50Ah)
1x matched charger (optional, if selected)
