Re: XPD: open-source keywin e-bike lab replacement

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.

Re: Xingyue X1/SeeyesDMB09A moped LiFePo4 pack build

I would recommend keeping an eye out for Chevy Volt cells. Zero cells are awesome, too, but rare. "Salvaged EV cells index, Leaf, Volt, Tesla, etc" https://endless-sphere.com/forums/viewtopic.php?f=14&t=89680 Went with your advice and got a 2016 chevy volt gen 2 16s pack. Its been reliable so far. ...

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

Re: Throttle dead zone fixes

Another simple solution is to open the throttle and glue some rubber stopper on the return stop ledge. Takes some testing with the wheel in the air. Ive been running it two years with no issues. Ive also adjusted the magnet positions inside for less throttle twist range. Avoid the $5 throttle. The m...

Do the sellers of these bms provide the android app or is hosted somewhere online? I've tried Google search and Play store with no luck.

Re: Chevy Volt Gen2 Batteries Los Angeles

Thread closed: bought a 2016 module from ebay. $16 per cell including shipping.

Advice: if you see a good deal or on carpart get it. I lost my chance. Packs are scarce now. Some were $10 per cell. One had only 5000 miles on it.

Re: Recent buy Chevy Volt battery module concerns

I plan to replace the threaded rods holding it together and add a handle at which point I'll inspect the pouches. How thick should the cells be? As far as condition, I just received the module so I have no real idea. The only thing i know is that it was from a 2016 Volt with 26k miles. I am trying t...

Re: Recent buy Chevy Volt battery module concerns

Attached. Bulge is 4.3mm/.17" on side in photos and 2.4mm/.09" on the other side. I think it needs more compression. When they are assembled together in the Volt pack the middle modules compress against each other. This must be one of those middle modules. Should I add thick insulated plates with th...

Recent buy Chevy Volt battery module concerns

Do the gen 2 Chevy Volt modules have a natural bulge to them on the ends? or is this a sign of internal damage? Just recieved a module and would like to test it, but don’t want to risk possible further damage if the cells inside are compromised. Seller claimed 24k mikes on the car. Voltages were 3.9...

Re: Chevy Volt 2016 or newer modules or cells

They use LG chem pouch. They are automotive grade so they need to maintain at least 70% for 100,000 mile warranty. Originally I wanted to use the leaf cells but they were too big.

The representative told me the peak discharge is in fact 2400A but he would not tell me the voltage drop at said discharge or at constant 60C
