Backfire 346Wh battery with LEDz

the Backfire site sells a 12s2p with 21700 cells claimed 70 amps peak tho
wires are 14awg with xt60 connector. The battery has LED strips on both sides with a micro JST type ? 3 wire BK/Wh/Rd connector. It is on a DIY build and I would like to have the lights go on. What are the steps to connect it to a motor controllers 3 or 5v pins? I fine with wiring to an external switch, it does not have to be controlled by remote.
