July 2, 20169 yr Just curious, since one seller of the same 48v battery gave me a 48v charger and the other seller gave me a 54,6v charger. Will one of them work better? Or is one actually bad for the battery? Let me know please! Thanks.
July 2, 20169 yr My Gtech charger is 41v, battery is 36v.. I think the battery has a built in controller to avaoid overcharging or damage. Maybe the higher voltage charger will charge it slightly faster?.

So, for current to flow into a battery (and charge it) the charger must be at a higher voltage than the battery. Sent from my HTC One_M8 using Tapatalk
July 2, 20169 yr Makes sense, we look for 14v/ 14.5v charge rate on 12v SLA motorbike batteries. Thinking about it the 48v charger would be next to useless on a 48v battery?.

There's a similar inaccurate naming thing with lithium batteries, commonly referred to as 24 volts and 36 volts to stay with the convention of those with earlier chemistries. In truth they are 26 volts and 37 volts, the first commonly having 7 cells of nominal 3.7 volts (=25.9) and the second having ten cells of nominal 3.7 volts. .

And the 10 cells charge to about 4.2 volts each or 42 volts overall.
