Re: 60V E 300 Hub Motor Project Underway

Mine arrived slightly damaged and missing brake cable and throttle plug was incompatible with controller plug. Bought it from vendor on AliExpress and fortunately got a partial refund because Ali does cover your ass. Haven't had a chance to hook it up yet but was finishing the fab on the frame today...

Overvolt OK?

Greets all. I'm getting ready to build a batt for my Hyper Racing scooter. Currently its a 16s which gives me a max V of 67.2. Hyper advertises these as 60v. Would it be ok to overvolt to 17s or would I possibly damage the controller or motor

Re: Novice batt builder question

It already has a 16s4p - or that's what I'm guessing since its rated at 13ah. Stock batt is 11x6x4 and ive got 12.5x10x4 to play with. Based on my new calculations I would be able to get 12-13s in there if I hot glue the cells. I might sacrifice some ah and go with cell blocks so i can get some cool...

Re: Novice batt builder question

OK, I'll try... If you take 20 batteries, each with 3500 mAh and wire them in PARALLEL, you essentially get the equivalent of 1 giant battery with a capacity of 20 X 3500 mAh = 70000 mAh or 70 Ah. But it is still only 3.7 volts!! You would need an additional 15 of these same giant batteries wired i...

This is the 36 cells colored in - I know they are going to be 65mm high but the footprint seems really small (i know I need one more negative in my series connections)
