A must-read for buyers before purchasing
1. Charge correctly with a charger of the corresponding voltage and volt. A charger with too low voltage cannot charge
If the battery is charged at an excessively high voltage, it will burst the lithium battery.
When lithium batteries are used in series and parallel, new and old batteries must not be mixed. It should be based on the same capacity and electricity
The pressure and internal resistance are connected in series and parallel. Inconsistent series-parallel operations can, at the very least, damage battery life, and at worst
Then there are potential safety hazards. Remember!
3. Do not reverse the positive and negative poles.
When the battery power is about to run out, please charge the lithium battery as soon as possible.
