Overkill uses Jiabiada (JBD) BMS's, they aren't actually made by Overkill. You can get them elsewhere for cheaper, but the advantage with OK is that Steve tests them all out before shipping, keeps them in the U.S, and offers a warranty.Hi Amy, long time no see.
Anyhow, concerning the BMS. I have never heard of any complaints from Steve's at OVERKILL.
Not that I keep checking. But of all the BMS makers. His is the only one without complaints that I have seen.
Looking forward to you being more successful in your adventures and starting anew in the USA.
Wow, I did not know that. I thought Steve made them himself. Thanks for the info.Overkill uses Jiabiada (JBD) BMS's, they aren't actually made by Overkill.

I have 5 different JBD units (not from ok), and all of them work flawlessly. Two are even the EXACT same unit OK sells.
Amy,Thank you all.
We decide to arrange few quantities of JDB 150A and 200A BMS to Houston warehouse to have the 1st try. If many customers want to buy JBD BMS and ship togther with our batttery cells that will be good choice.
Thanks again
Amy Zheng
Loving mine, (16s at the top) little 300ah addition is great, thanks @Amy Zheng now @ 1002 ah of 51.2v, joe.Received my 280 AH cells yesterday and the last package today, all cells are sitting right on 3.30 volts each and appear to be brand new with the barcodes intact. Nice job Amy and thank you, I am considering duplicating that order in the near future.
I noticed on the Gyll modules you parallel them at a busbar rather than daisy chain them. Have you found that works better than daisy chaining?Loving mine, (16s at the top) little 300ah addition is great, thanks @Amy Zheng now @ 1002 ah of 51.2v, joe.

Each gyll is already 48v, no need to series them. If your talking about going from Gyll to Gyll, they are supposed to each go to Bus Bar like in the rack they sell and yes the Soc remains constant this way, Joe.I noticed on the Gyll modules you parallel them at a busbar rather than daisy chain them.

Ok thanks. I have seen them paralleled both ways, but i thought all the power in a daisy chain pulled through the master was not as efficient, but the manufacturer's seems to build them like that.

Ok thank you AmyThank you.
Currently, We also can sell 8S 24V BMS from China. The BMS ship by air also very fast, just the shipping cost a little bit expensive from China.
