Communication Ports

The Rover Boost has a reactivation feature to awaken a sleeping lithium battery. The protection
circuit of lithium battery will typically turn the battery off and make it unusable if over-discharged.
This can happen when storing a lithium battery pack in a discharged state for any length of time
as self-discharge would gradually deplete the remaining charge. Without the wake-up feature to
reactivate and recharge batteries, these batteries would become unserviceable and the packs
would be discarded. The Rover Boost will apply a small charge current to activate the protection
circuit and if a correct cell voltage can be reached, it starts a normal charge.
