For Sale here is a link new LiitoKala electric bike 36 volt battery with a total capacity of 10 Amp Hours. This battery came off an electric bike I built for a friend who only used it a few times. He just upgraded to a new controller and 48 volt setup. I just tested the battery with my meter and is putting out 41.8 volts which is near 100% new capacity. I don't remember the BMS it has onboard but I suspect it's a 20 Amp. This includes a soft battery mounting bag with velcro straps and also a 36 Volt 2 Amp battery charger.
As per the label battery, this is a 10 series 3 parallel batter (10S3P) consisting of 18650 cells with 3350 mAh capacity, hence the 10 Ah capacity of the battery. There are a lot of mislabeled eBike batteries out there but I have used quite a few of this brand and they are good quality. In regards to what will this battery will power well, this was used on a 350 watt rear wheel drive electric bike. It would power a 500 watt motor fine, anything bigger, you might not get a tremendous amount a range. I also have a few other 36 & 48 Volt eBike batteries for sale here. Thanks for looking.
