It was a faulty BMS. For some reason the ghetto charger didn't work (I adjusted the pot on the stepdown board to get 4v with no load but once connected to the cells it didn't seem to be charging) so I ordered an Imax B6. By the time that arrived a few days had elapsed and the low group were...

Yes, it's a basic 42V 2A li-ion charger. I got the Samsung cells and Vruzend kit from nkon.nl, who have a good reputation this side of the pond, and the BMS, which does have balance wires, from Amazon. I plan to charge and monitor the low group as fechter suggests once the stepdown board...

Thanks for the reply. I'm fairly hopeless with electronics but figured the resistor is to reduce the 5v to 4.2v? But I didn't understand how it would not just reduce the current. So I found an adjustable step-down module cheap on ebay and have ordered that. I don't have a voltmeter as such but...

Hi, I've just got back from my first ride on my first e-bike, which was curtailed because the BMS cut power from the battery after 2 or 3 miles. The battery is a 5P 10S I built using a Vruzend kit. Disconnecting and reconnecting power to the controller got me going again but the same thing...
