SirGeraint Posted July 31, 2015 Share Posted July 31, 2015 There are 2 pairs of wires coming from the Ninebot's battery. Obviously the heavy duty one is for the motor to use. Anyone know what the other one (with a Yellow and a Black wire) is for?Thanks. Link to comment Share on other sites More sharing options...
esaj Posted July 31, 2015 Share Posted July 31, 2015 Probably charging, they should connect to the charging port. Link to comment Share on other sites More sharing options...

If it's watts, you can calculate the amperage by dividing them, as P = UI <=> I = P/U, ie. watts / voltage). Even pretty small wires and connectors can take several amperes without overheating.Edit: I recall seeing the voltage of a Ninebot battery being marked as 55V on the packs (15S packs instead of the usual 16S), so the voltage on the charger is probably smaller than 67.2V too.

It was the charging wires. Good to know. I unplugged them and plugged them back and the LED on the Charger changed from green to red.Thanks.
