Battery capacity and external charging
Re: Backup Battery
I'm struggling to understand what the capacity of our battery is. I get 353Wh based on the 4 x 12.8V modules at 6.9Ah for each module. But people are claiming one full charge from a hover board battery and the carvepower 36V x 4.4Ah is only 158Wh!
the other confusing bit is that OW charges in supposedly 20 minutes from dead. this means 58V x 3.5A for 1/3 hours is just 68Wh!
seems to me the rated capacity on the pack is much larger than what it accepts during charging.
anyone have any sanity checks here?
I think the battery is closer to 2200mah..
You can charge at higher amps, I've been charging at 5amps for quicker charges. I heard sonny was charging at 9amp for 15min recharge time..
where did you get 130Wh?
