1、Stable Performance: The protection board adopts chips with high protection accuracy, low damage rate, high power, and low internal resistance to ensure that the lithium battery is safer and more stable. 2、3 Proof Glue: The circuit board is brushed with 3 proof glue, which is waterproof and anti static, and ensures your lithium battery's safety. 3、Open Heat Dissipation: The layout design of the protection board is very reasonable. The open heat dissipation can greatly improve the heat dissipation speed. After 25 minutes of discharge, the temperature rise is lower. 4、High Current: The lithium battery charging protection board is small in size, but the continuous working current is 70A high current, which is easy to use. 5、Strong Compatibility: The protection board is 3S of 12V protection boards, which can be applied to 12V or less than 900W inverter batteries, such as ternary lithium, lithium manganese oxide, lithium cobalt oxide, and lithium polymer batteries.
