Should i be concerned if my volt cells are 0.01 diff when discharged ? With spim08hp they were 2v diff. And i balanced the spims every cycle

Can’t find Chris’s spreadsheet do you have it bookmarked by chance? Has anyone here made anything like it? Its awesome I'm going to make one on google sheets and share. People can contribute.

Yes check out my youtube video. https://youtu.be/A4ayry1iSeU AZ lithium added a metal strap to resist bulging. Not sure what the full pack has for this. The module dropped right in. I am very happy with it. Ive never balanced it in 5 years. I get 0.01 v diff at 50v and 0.001v diff at 67.2v. I...

The gen 1 volt are a tad low on energy density and volume, but could be okay for razor dirt bike.i have a Gen 2 60v 16s 3.1kwh i got for $550 shipped from AZ lithium i think he still has a few of them. I agree a full pack will be best bet. Ive seen some under $2k gen2 on car-part. Id make some...

Looking for LG chem or other name brand pouch cells li-ion with low miles (car packs) or low cycles. Looking for pouch cells Tested Matched (similar IR and capacity) often case with cells from same packs / modules West Coast USA preferred but anywhere else in US okay too. $100 kwh...

Thanks for advice. Where do you measure temperture from? I hear people say measure at the axle if your controller does not have a temp probe inside of it. I measure mine on the phase wire where the motor connects to the controller. Probably too far from the motor to get an accurate reading of...

I never thought of that next time I ride I'll check that out. I've been measuring temperature at the phase wires near the controller and I stay bellow 50 Celsius. You think I can push it up to 60 Celsius if my hub motor is still under 65cel/150F?

Hey where do you have your probe mounted externally? Would a non contact IR type be a good idea attached to the swing arm pointed straight at the windings with a few mm gap?

What diameter is your hub motor on your scooter/moped? Mine is 8” on 10” wheel. I can only run 7kw for 15 minutes before the phase wires are heat to 60 celcius. Im thinking of some 0w oil in there or maybe glue on some ugly heat sinks as a last resort. I can achieve 80kph @67v with flux...

@ Dui I’ll look for some grade 12.9 m4 bolts and seal it with silicone. I was amazed when I opened it and there was no rust after 10 years with frequent rain riding. Btw I posted a question to your moped thread.

Sorry to revive an old thread, but I'm worried about the silicone being too weak. There is a lot of sheer force going through eighteen 1/8" screws. Is there a strong glue for this purpose? Silicon is pretty soft. Something between silicon and jbweld would be perfect.

Just left scorgforge looking for the apk. Now I know it needs to be manually compiled. So you've both managed to edit and upload a profile? Can you download one too? I really could use this. Please apk and bluetooth tutorial. Id pay for the effort to avoid forehead surgery, and furniture...

Went with your advice and got a 2016 chevy volt gen 2 16s pack. Its been reliable so far. I need 18s or 20s module or multiple 6s modules for more voltage and top speed. Right mow I rely on my controllers flux waakening speed boost but it kills my range. With the 16s module I see 0.05v...

Eee291 Did you disassemble the pack yourself? If so how did you keep the tabs fully intact? Thanks.
