That guy was smart. I did not realize the necessity of doing that. Now the damage is done. It may be worth replacing just those two cells. I need to ponder that seriously since Shunbin may not honor the warranty.

There is a long thread, link in my sig, It appears they have pulled their ads out of Amazon.ca I haven't checked on amazon.com. I have some electronics background and when I saw the BMS I immediately knew I had to get that out of there, my 3 year old could have done a better job. Ugh, don't wanna think about it.

Please goto Amazon and REVIEW your issue with the blown BMS & two leaking sells. (photo's too) and I think they may be more inclined to resolve the issue, they did refund me $300 USD for their screw up which barely covered the cost of the repairs.

You can swap out cells BUT you'll need to match then up and that may be a challenge to get. MIne are AYOUPOWER 174AH which they discontinued (no longer listed on their site) and the closest they have is 180AH now and don't retail. You'll need to find out what the cells are by locating all the markings and searching them out on the web, QR codes "may" be helpful.

I'm prepping to building two more packs with Deligreens CATL 200AH cells, 2x 24v/200AH packs of 8 cells in series with BMS8T bms. Unfortunately the Chinese New Year shutdown tossed a wrench into those plans for the moment.
