A new external pack expansion port for the FTB Solar Generator. This is an external 100A/h battery pack to use with your generator. Whenever connected, it functions as if you had three internal batteries. Outputs will now drain the external pack first. Once the external pack is empty, it will immediately switch to using the internal battery. When charging, your unit will fill its internal battery first. When the internal battery is full, it will immediately switch over and start charging the external pack. Do not try to charge the external pack separately from the generator without using the designated charger provided by Lion Energy.
