Important Precautions

1. This lithium battery protection board should not be used with lithium iron phosphate batteries or specific electronic devices such as hernia lamps or electric drills.

2 . Ensure that products requiring a discharge current of over 3A have a discharge rate exceeding 3C.
3 . The multiplier formula indicates that a battery rated at 2000mAh capacity will yield different working currents based on its C rating (e.g., a 1C rated battery provides up to 2A).
4 . Prolonged use under high load may cause overheating; avoid extended operation under these conditions to prevent damage.
