The battery mod integrates its charging circuit directly into the PC Engine GT, thus preventing the battery from overheating during charging. This secure battery mod also includes the "Charge & Play" function, allowing you to play while the console recharges.
The battery offers at least 8 hours of battery life. It recharges via the DC port using the provided cable, which plugs into a standard 5V USB charger. It is also possible to add a USB-C port to the side of the console for easier charging. A red LED, visible in the battery compartment, lights up during charging.
This mod replaces the original batteries and voltage regulator, thus improving the power supply.
