Anyone else hate their Fatshark batteries? I have two of the newer style ones and they both are horrible. Really high internal resistance, IR, from the start. So I finally got around to creating an 18650 version of the fatshark battery mods. Why 18650? While they are Lithium Ion they are listed at a 4.2 max. They are readily available. They are cheap. What more could you ask for? In a slightly bigger package I am cramming 3400mah versus 1800mah… and a better IR.
So let’s get started, what do you need?
- 2x 18650 cells (I used Panasonic NCR18650B)
- 1x 2.1mm Barrel Plug
- 1x Balance Plug JST-XH**
- 3x Balance Terminals**
- 3x colored 26 awg wire
- 1x 2S Battery Balance LED
** When you buy from DigiKey I suggest ordering more. I also suggest ordering some 2S, 3S, 4S and higher plugs so that you save on shipping.
