Not even remotely interested in selling BMS. There's a good reason EM3ev, Luna, and others stopped selling BMS 6 or 7 years ago. Many buyers haven't a clue as to how to handle or install. Many good BMS were returned for warranty when they were probably killed by a n00b.Those bms need to be tested to know if full working and safe
Nope not in this lifetime. I offered to picture the labels. The labels can be translated with Google.have a nice time testing bms's![]()
I have them because we insisted UPP give the shop replacements in order to be able to send them out to purchasers if we suspected a BMS. Additionally when Rechie came to the shop he brought a few more for me to use when I was still messing with battery build/repair. I can't match the quality of EM3ev. In the end I just buy a complete battery. I will be offering the building tools and supplies in the next month or two as I sell off all my specialty bike and ebike tools.
see response to batteryGOLDTomjasz did you buy all those bms's or they come off a old packs.
They areThey look brand new ?
I'm not selling BMS, I'm sorry if I mislead you.And how much they cost ?
One? Meaning you. And perhaps a large cross-section here. But as legislation slowly creeps into our hoppy better protection and protection circuits and balancing will be needed for finished battery UL certification. UL certification seems to be the direction prebuilt eBike batteries are moving.That's why all one really needs is a good BMS with overvoltage protection and undervoltage protection.
I think all were from UPP. The shop I worked for sold UPP batteries for over a year and because of the high failure rate we insisted in a stock of BMS for warranty replacement. In the end, we decided encouraging kit buyers to make a repair was not a good business plan.Looks like you have a heavy duty one on the far right you didn't buy that from UPP did you ?
