Hi,
my nephew bought a 20" Avaka BZ20 which has probably Bafang 250W (peak 500W) , 15Ah battery and it ran about 200km.
Last miles it tended to stop during driving. Later on just few meters I was able to drive it, and latest status is that after accelerator pressing only maybe 1/4 of turn of wheel is performed. Cant do any movement.
Observations: I noticed overvoltlage protection Error 07 on display for a while - not persistent,
Battery drops from 2/5 pieces to zero after doing nothing with it for 2 hours.
Battery was charged again to full, put back and display is shown EMPTY battery.
Motor is doing still only 1/4 of turn.
Description on the internet is that it has 48V battery. I have also tried set P14 (
overcurrent protection) from default 12A to 14A but cant help.
What is wrong? Thanks a lot
