How to Add Another Battery to the Bluetooth, FM Radio
🔵 This video shows you how to install another lithium ion battery to the Bluetooth, FM radio to keep it powered and working longtime.
🔵 Also, installing another 3.7V lithium-ion battery to this radio will not damage its internal circuit components and will not change the voltage. Here, the device's battery and the additional battery that will be installed will be installed in parallel.
🔵 This gives a 3.7V value to the radio in both batteries and only the milliamperes(mAh) increase. No matter how much the milliampere(mAh) increase in the two batteries, there is no harm to the device.
