Feature Request: Add 3500mAh Battery capacity about uv-k5-firmware-custom HOT 3 CLOSED

Are the ones available on Aliexpress? But they cost more than the complete radio; the radio can also be found for 17 euro including the 1600 mAh battery, the 3500 mAh battery alone (declared but you should check if it is real) costs around 20 euro. Of course everyone has their own needs but perhaps it would be better to buy the second complete radio, in order to have the second spare 1600 battery to take with you.

Plus buying the complete set, you get a spare dock and a spare radio handset! Though yes, each to their own, some people don't want to have to carry a spare battery and would just prefer one slightly bigger to carry around.

This was discussed in #130 and #266.

1. This is not a stock quansheng battery
2. I don't have one to determine the discharge curve
3. There is a good chance that one of those that are already available will be good enough, otherwise you have to modify or add a new one on your own:
