1) I plug the original battery into this male xt30 wire: To view images REGISTER or LOGIN for full access.
2) I connect the same wire to a screw connector or something similar, like this thing: To view images REGISTER or LOGIN for full access.
3)I connect the screw connector to a female xt30 wire: To view images REGISTER or LOGIN for full access. at this point the connection from the original battery to the circuit board is simply connected trough a longer piece of wire.
4) I connect a t type wire to the external battery with this wire: To view images REGISTER or LOGIN for full access.
5) I get another screw connector and a longer piece of wire to simply extend the t type wire and pull it trough the frame.
6) Shove the extended t type wire into one side of the first screw connector, double penetrating it. (maybe I find a Y or T shaped connector so I dont have to double penetrate, but the idea is the same)
I suppose I am leaving out the car fuse people usually put in, but why is it even necessary? The original battery doesnt have such fuse in the wire. If its really necessary, I suppose I can connect that with one of those screw connectors too, as the fuse holder comes already with a wire attached.
