I have been working on a replacement battery for a lawnmower(28.6V @ 6A)
I have built the battery (7S 7P) and everything works fine. I put the battery in the case and tested the voltages for and I am at 28.64V.
So all good.
Put the battery in the mower and test it, the mower starts fine and cuts my front lawn with no problems.
Take the battery out of the case and add BMS to it (25A rated) -https://www.aliexpress.com/item/400...earchweb0_0,searchweb201602_,searchweb201603_
Put everything back together and then test out the mower.
Mower starts up, then dies.
BMS seems to reset after 2 sec, and then the process repeats over again.
I am thinking it is a bad BMS, but maybe I do not know enough about BMS' and purchased the wrong one/style/model.
Any help would be appreciated.
