[IMR or only li-poly]

Hmm, my 2s Boxer DIYkit is about to drop in (when it finally gets through customs), so I'll have to build it twice, once now without the protection and then rebuild it when I finally get the protection board. Hope it'll still fit in there

A question: what would happen when 1 battery's installed incorrectly?

[IMR or only li-poly]

Xavier, don't go on the colors used in Cisco's diagram. On the balance connector he means bottom black to GND, then red to 1, black to 2 and top red to 3. Guess he assumed everyone would read it like that. If you use a connector there you can switch between a lipo and imr pack Optionally you can bridge - to GND and + to 3 on the board and only connect wires 1 and 2 to the bridges on the sled. Be advised that any 3*1s setup should wait for the specific extension board to provide single cell reverse battery protection.
