I've been looking for a 2nd battery for my Super Soco TS1200R, the big struggle for me is that the original battery of the super soco very expensive is. I've found a cheaper and bigger battery on some sites.
My question is, are there people who have a not official battery in there Super Soco TS/TC? And how did you guys did that with the cables etc.
You need to add 2 wires to the controller (+ and -). If you want to use 2 batteries at the same time, you need to make sure they have same voltage. I also recommend using batteries with the same capacity. You can buy original and non-original batteries on taobao (fits perfectly), good luck.
