Hi I've just been setting up new Kelly controller and for some unknown reason it's drawing aprox 6a from battery when motor not moving but it's locked firm in place. I've obviously screwed something up in the settings. Any 1 able to send me the default settings so can go back to that and see what's ...

Re: How to choose a hall sensor?

Does it even make a differance what hall sensors you install?
From motors I've done it doesn't seem to as long as they are all the same type they seem to work fine

Re: E-S Stealth Electric Bike Owners

I built a 20p 12s battery pack for one of these stelth's aprox a year ago using cells from a Tesla Model S battery pack. I had to file off a little from battery opening and it bulged past the side of the frame aprox 5mm each side but didnt look out of place. It made the bike very heavy but from full...

Re: Dual battery system Li-ion & LeadAcid powering house

Yes that was the plan for the PW2 to not get up to max voltage (54.2v) hence why I increased it to be a 13s battery. If was a normal 12s battery then the lead acid ones not be able to get fully charged and I know that's not a good thing. I have an ant bms fitted to the PW2 that can be seen in the pi...

Re: Dual battery system Li-ion & LeadAcid powering house

So im right in theory then, I can hook them together providing they each have their own charge capability's that's great, its quite confusing when some sources say yes its possible yet others tell you no its defiantly not. The 2x inverters are paired together (one master and 1 slave) with an add on ...

Dual battery system Li-ion & LeadAcid powering house

Hi all, I currently run my house on 48v battery system (lead acid) and recently got hold of a damaged Tesla PW2. I have repaired the PW2 and modified it to be a 13s config rather than the original 12s it came out the factory with. Its inverter has been completely removed so because of that its essen...
