Korg Volca 18650 battery mod
Description
Making famous Korg Volca series even more portable. The removable battery tray is replaced by a two 18650 li-ion cell holders. The maximum output voltage is 8.4 which is perfectly fine for the Volca. (It actually can take from around 5.8 to 17 volts as input, with the stated 9V being just a median value). This mod will void any warranty as it requires disassembling the Volca, removing 6 AA battery tray and desoldering its connections from the board so it will require basic assembly and soldering skills. You have to have at least slight idea what you are doing and know a little bit about lithium batteries. I am not responsible for any damage you might do to your synth in the process. I would also recommend instaling a tiny (8x40mm) 2S BMS glued somewhere on the new tray. This way you will be able to actually charge your Volca with the standard 9V wall adapter without removing the batteries. The BMS can take up to 9V and have overcharge protection so you don`t need your power supply to be exactly 8.4V required for 2S. Tip: if you have installed everything including the BMS and the Volca won`t start - plug the wall adapter for a few seconds. This will unlock the BMS and the Volca should start normally. Repeat the procedure if you remove the batteries at any point. Have fun!
