Sorry, no images but its very close to you mod Thanks you for idea, i did similar mod for my BF888 battery Cut the wires even and solder them together, (respecting their polarity) to the top battery contacts and tuck the wires carefully in the small spaces next to the springs, don't tuck it behind the battery. Use your multimeter to double check the polarity of the usb board while its plugged in, the battery and the contact labels on both the top and the bottom of the battery.ĥ. Once you are sure everything is set, don't worry about gluing it or taping it, there will be enough pressure between the tape and the board to keep everything together.Ĥ.
DO NOT force anything here or it will not work!ģ. Play around with fitting it, It should just barely fit behind the usb plug and between the contacts on the top if there is any pressure or it doesn't fit right make sure you adjust the board. Now that the board is secure and your wires are ready, make sure there is nothing exposed on the cell, the entire thing is positive and it must be completely covered in tape or else it might rub off on the board and short circuit!Ģ. Also I'm willing to assemble a pack for anyone not willing to do it themselves for a reasonable price, just let me know in the comment section and I will try to get in contact with you.ġ. If anyone reading this finds errors in my work please let me know. If a lithium battery is punctured it can catch fire almost instantly, but can be extinguished by dumping sand on it. One suggestion is to work on a non-flammable surface and keep a small pail of sand nearby. You may want to make sure the battery is dead before you do this or it might explode badly. Nor will it modify the radio itself, everything will fit inside the removable battery and can be swapped out on the flyīe 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. This mod will not remove the ability to recharge on the standard base. 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. Recharging with a USB hub took two and a half hours. The radio is rated at 500ma so any standard USB charger will give it enough current.ĭischarging the battery completely by leaving the radio on (with flashlight) and battery saver enabled took three and a half days. This is a relatively simple mod for a Baofeng BF888s model UHF HT radio to allow recharging its battery via USB.
