4S 40A Lithium Battery Charger Protection BMS Board Li-ion Module 14.8/16.8V

4S 4 Series String 16.8V Lithium Battery Protection Board 14.8V / For Power Tools Drill Straight Diy

4S 40A Lithium Battery Charger Protection BMS Board Li-ion Module 14.8/16.8V

SKU:012746
Regular price $4.99 USD

 

 

 

 


 

 

The protection board uses a mature 4 string dedicated lithium battery protection chip, with high integration,
high sensitivity characteristics, through the detection of the battery voltage, charge and discharge current
and ambient temperature and other information on the battery overcharge, over discharge ,
Discharge over-current, short circuit, charge over-current, temperature protection and other real-time protection,
but also through the external circuit to achieve the adjustment of the parameters.
The protection board program design mature, worry-free, is your trusted product.
