The price is for the price of the protection board. If you have a single battery, please contact us;
Lithium battery use common sense:
1, must use the standard lithium battery charger 4.2V charging.
2. Prohibit large current discharge (with protection board will automatically control).
3. Over-discharge is prohibited. The voltage of a single battery should not be lower than 2.5V (with the protection board will automatically control).
4. It is strictly forbidden to disassemble or short-circuit the battery, which may cause short-circuit fire.
5, the use temperature -20--60 ° C.
Precautions for use:
1. Rechargeable battery. Do not discharge. Discharge.
2. When the battery without the board is lower than 2.75V, it is forbidden to turn it on again. It must be charged. (Easy to over discharge).
3. When the battery without the board is fully charged, it must be taken down. Otherwise (easy to overcharge).
4. Please use a qualified charger to charge.
Charging limit voltage: 4.25±0.05V Cut-off operating voltage: 2.75V
Standard charging current: (0.5C) Maximum charging current: (1C)
Standard discharge current: (0.2C) maximum continuous discharge current: (2C)
It is best to carry out a complete charge and discharge cycle for each use, which is beneficial to prolong the life of the battery and maintain performance. Do not arbitrarily disconnect the battery during charging. For batteries that you want to use for a long time, fully charge the battery and keep it insulated. Charge once a regular time.
