| mini powered mp3 speaker battery replacement??
i got a small mp3 powered speaker i run in my scaler. it only lasts about 2 hours on a charge. anyone know if i could crack it open and hook up a 3 AAA holder to replace the 3.7v li ion battery,and run 3 rechargeable AAA batteries i tried it on the first one i bought using a single 1000mah 25c gen ace lipo cell, and all the smoke came out of the board in the speaker. to much battery maybe? |

MAybe a BEC set to 3.5 volts ran off of the main battery. I am not sure the BEC will go that low, but it might be an easy way to power it, and if you run a big battery in your scaler, you probably would not even notice the loss
