24V100AH Rechargeable Lithium Battery Pack Light Weight , Lifepo4
Battery Pack Fast Charge
The battery pack support Bluetooth communication function. Through
Android and IOS APP, can read the battery status and information.
Especially due to the Android system’s openness, different smart
phone manufacturer will have their own different Bluetooth hardware
version and customized feature Android systems. So the APP may not
work well on some smart phones(with Android system) due to
compatible issue. It is necessary for the customer to confirm
whether the phone is compatible for the APP.
