Safety Test

No fire, no explosion

Charing to 3.7v and do nail penetration test, there is no fire, no explosion, no any other obvious changes.

Nail Penetration Test and Overcharge Test

After testing, no fire and no explosion, that is definitely approved than our lithium batteries deserve you.

4. Circuit Protection

The batteries are supplied with a LiFePO4 Battery Management System (BMS)that can monitor and optimized each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge, short circuit. Overall, the BMS helps to ensure safe and accurate running.
