I have searched the fourm and could not find any other thread that matches this topic. I know on the inspection sheet it says vex official batteries, but on certain items you can use vex equivalent items of the same type. So my question is can i buy other branded batteries other than vex that are the exact same voltage and capacity rating making them on paper the exact same.
No, the only legal batteries are any of the VEX 7.2V Robot Battery Packs.
