I've obtain the spec for this motor from QS, it looks like the rotor from your video illegalbike does not look like what they show in the specs... a bit strange.

I can see it now, great video. What adventure does the encoder has over hall sensor?

Video does not show...

does not look like that encoder is water proofed, how's the general water proofing?

???

I'm betting my house it's nominal lol

Understood. In parallel it IS one big cell. Please tell me they are Lithium -Ion, NOT LIfePo4, like I am assuming, and the inherent 4.2v charge voltage vs the 3.65v charge voltage of the two different chemistries. Please eas my mind. I may be wrong.. but.. I have installed over a hundred...

They are Lithium Ion :).

I meant for each cell, not for all of them. In any case, I do not have anything the can remotely provide 50A :)

OMG that made a massive difference! Now it's pulling 10 amps! Thanks.

So here's the scenario. I have 5 50Ah cells in parallel. They can do 1C of charging which means they can pull 50amps. Currently they are at 3.69v When I set the PSU to 4.2V CV and hook it up, they draw only 2.5AMP. If I momentarily bump the voltage higher they draw more amps. This...

I've got a lithium-ion battery that can do 1C. It's rated with 50Ah capacity so in theory it can handle 50amp changing. When I hook it up to a charger, or a lab power supply and feed it with 4.2v it only draws about 3amps (being at 3.6V at that moment). I don't quite understand how fast...

Hey all, I've upgraded my SurRon with a far drive ND72530 controller and I'm hopping to preserve the original speedometer. However, I don't think it uses standard signal. The controller has two wires for speedo connection, Phase wire and analog wire. Phase wire can also be configured as a...

I have a 60v charger and a 72v battery, can I use a DC to DC booster to charge it? Wouldn’t the charger get confused thinking the charge is finishing?
