Battery Protection Module Durable Practical Small Lithium Battery Protection Board For Battery 5 Cell

Battery Protection Module Durable Practical Small Lithium Battery Protection Board for Battery 5 Cell Specification: Item Type:Battery Protection Board Type:3 Cell/4 Cell/5 CellOptional Continuous Current Capacity:20A Instantaneous Current Capacity:40A Battery Voltage:3.7V Package List: 1 x Battery Protection Board Note: B line C line apply thick wire connection and ensure that the positive and negative pads of the pad and the corresponding device are soldered correctly. Before installing the protection board the battery must be well matched the voltage difference between each battery is not higher than 0.05V the internal resistance difference is not more than 5m Ohm the capacity difference is less than 30mAh and the protection board each batteries as as the battery voltage is too high or too low the board can it. The better the battery consistency the more durable the entire battery and the better the performance of the protection board. A single battery must be connected in parallel with the required number of battery packs and then used in series. When connecting three batteries in series make sure that the voltage of each battery is the same. If not fill each battery separately and use it in series. In the discharge test the battery with three greatest voltage drops is a bad battery. Do not mix and bad batteries. The capacity of the battery pack should be as close as possible to the internal resistance. This protective plate cannot be used for lithium iron phosphate batteries. It is strictly forbidden to use the lithium battery protection board in series.
