at my charger end i have 27v, at the controller chargeport i have 27v but my battery wont charge more then 17.4v. does it mean my battery is stuffed ?
also because its a 17.4v when i multi-meter the throttle end i get .56v is this because the controller has detected voltage below 20v and shutoff power getting to the motor ?
The 0.56 Volt throttle reading could very well be due to the low battery pack Voltage and the controller's low Voltage cut off circuit.
I ended up putting the single 12v battery into a car charger for around 6hrs. then i put it back into the batter pack and then charged it again with the 24v charger. seems to charge now. and bike is starting correctly.
Ill have to do a load test but i think its ok.
I also tried this method on a few other battery and seemed to have bounced them back from the dead now.
hmm ok so i have a set of 2 x 12v 12ah on the bike after 3 days of nothing they are both reading 25v.
i then have a set of 2 x 12 9ah. both seem to be discharging by themselves. i took a readying 2 days ago and it was at 19v. today its at 7v.
im guessing the batteries are stuffed ?
