Warning
- If you want to use this protection circuit board for a battery that is less than the rated drain, you must add additional protection device to protect the battery itself. Such as: proper rated polyswitch.
- You must be professional in Lithium battery pack to buy the protection circuit board. Misusing may cause battery damage or explode.We are not responsible for any damage caused by user.
