5pcs Bms 5s 21v 18650 - Lithium Battery Protection Board Polymer Cell Circuit Charging Board Module

Opis produktu: 5pcs Bms 5s 21v 18650 - Lithium Battery Protection Board Polymer Cell Circuit Charging Board Module

The battery has superior with protecting circuit to prevent overcharge, over-discharge, over-voltage, and short circuit, extend life.This protection board adopts mature protection circuit, IC, high current ultra low internal resistance MOS and has perfect and stable charging and discharging protection functions.Small volume and current can be used in high current applications such as power tools and models.B-, C- should be connected with thick wires, and that the pads are soldered correctly with the and negative terminals of the corresponding equipment. installing the protection board, the battery must be matched (the voltage difference between each battery is not higher than 0.05V, the internal resistance is not more than 5m, the difference of the capacitance is less than 30mAh), the better the battery consistency, the the battery life, and the best performance of the protection board.This protective plate cannot be used for lithium iron phosphate batteries. Lithium battery protection board is strictly prohibited to be used in series.Colour:redMaterial:plasticPackage Contents:5 * BMS 5S 21V 18650 - Lithium Battery Protection BoardOnly the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
