This is a relatively simple mod for a Baofeng BF888s model UHF HT radio to allow recharging its battery via USB. The radio is rated at 500ma so any standard USB charger will give it enough current.

Discharging the battery completely by leaving the radio on (with flashlight) and battery saver enabled took three and a half days.

The problem is the with programming cable device driver. It is supposed to be PROLIFIC compatible but evidently is a bogus cable, so it won't work. I uploaded the Win7 Device drivers to the files section of the UV-3R Yahoo group, so join that group and they are there. The simple installation of USB cable drivers changed with operating systems after Win-XP. Vista, Win7, Win8 and Win10 all try to install a driver of their choice instead of one that actually works with.

With this mod the radio's utility expands several fold, now instead of being restricted to a 12V car battery eliminator (it will not recharge the battery) you can recharge the battery at the same time you use it in many different situations and not be restricted to the standard 120V AC recharger base.
This mod will not remove the ability to recharge on the standard base.
Nor will it modify the radio itself, everything will fit inside the removable battery and can be swapped out on the fly

Disclaimer:
Be warned you will be taking a lithium ion battery apart, don't force it, puncture it with a tool or generally abuse it or you may have a very bad time. Treat it like the bomb it is. You may want to make sure the battery is dead before you do this or it might explode badly.
One suggestion is to work on a non-flammable surface and keep a small pail of sand nearby.
If a lithium battery is punctured it can catch fire almost instantly, but can be extinguished by dumping sand on it.
