So I rode if 7.5 miles, but it seemed a little anemic - battery reading > 50volts after the run so the pack seems good. Please review here!

QUESTION - please review the functions of my resurrected Faraday - is this how it should be working? My concern is the throttle setting does not seem to matter, and despite 50 volts at the pack (after an 8 mile ride), its still feels sort of slow and barely assistive... Youtube Video of my...

I got my 48v water-bottle battery ($172 @ Amazon), drilled holes for the cage, soldiered up the power cable and it all lit up, motor started spinning with pedal action!

…and I got my waterbottle battery pack, drilled some holes for the cage, soldiered up the power cable, turned on the pack, the controller and headlight lit up! Moving the pedal and the front motor started spinning…

Okay, I got my waterbottle looking lipo pack, drilled holes to mount it, soldiered up the cable and it worked!

And even more - peeled the aluminum pipe apart. A network of wires between the cells is in play to make the 24 cells into an 12s2p in this 3x8 pattern

Corrections - tube is about 20” long - about 8 x 65mm, so its still 24 cells! Crazy wiring likely required to get 12s2p in this 3x8 form factor.

Btw, I cracked open the battery - looks like 3 cells per row. Broke the BMS hidden in the far end. Picks below

After mulling it over and convincing myself the battery is bricked, I took started taking it apart. first step is to drill out the punched- in dimples holding the ends And then some knife edge, screwdriver and big pliers And the top pops off to reveal 3x batteries per cell Drilling and...

I left the stock battery on the charger overnight with a Kill-A-Watt to see how much was going into the charger. A consistent 3 watt draw with all red-lights solid on the controller, 20ish Watt-Hrs burned. No change to the performance with charger unplugged - everything still dead. Assuming I...

Should I crack open the battery case and check the individual cells? I am poking around with multimeter, get nothing except continuity between 1 pin of the triple connector and one off the quad connector (I assume a ground)

Controllers are pretty stable then vs battery? What guys do batteries out there. -T

Thanks I will check out “Grin”. Yes, I expect to swap out all the electronics. I was hoping to find an Arduino sitting there with jtag pins on the controller, just sealed boxes and proprietarty parts :(

Hey thanks - Faraday is/did run overvolted, battery is well over 36v

I am looking at swapping out the suspect electronics and battery on a dead Faraday I purchased. Assuming the motor 8Fun is a Bafang and works, looking for parts - was hoping there was some consensus on standards or parts to get/avoid...
