Did you replace your BMS with an Ann Power?

Ann power BMS I found have always been good better still if one gets one with a switch, sadly though they don't (or didn't) when I wanted one make a smaller 12s one . One reason why I tried the acronimic BeMuchSafer brand.

Good point about the switch - it's weird that on the ANNPower store...

...there are no 36V 10S BMSs above 20A which have anything other than a temperature switch, but a switch can be fudged using the temperature switch wires, as shown by "The Battery Doctor" on the 40A. Maybe Sur-ron owners never need to switch their bikes off, because of constant need for speed or something.

You can put your own switch on wherever you want. You can put it on any of the sense wires, which makes a good test that the BMS is actually working too.
