Golisi 21700 3750mAh 30A Battery Spec:
It's generally safer to use an external battery charger if you as using a device with 21700 batteries. The reason for this is that you protect against wearing out your micro USB port and most external battery chargers deliver more balanced charge which prolongs the life of the battery and the device.
Always ensure that you never use damaged batteries in either your device or separate charger as battery wrapping protects the device.
If your device uses dual or triple battery configurations make sure you use the same brand of batteries with the same level of charge.
