4S 100A w/Balance 3.2V LiFePo4 LiFe 18650 Battery BMS Protection Board 14.4V
This product is 4 string 12.8V LiFePo4 Lithium iron phosphate battery power protection board. With a balanced, same port 45A discharge. With heat sink.
Protection board with overcharge protection, over discharge protection, over current protection, short circuit protection, temperature protection.
Products with 10 MOS tube, powerful cooling aluminum, continuous current limit of 100A. Applicable to inverter, xenon lamp, solar street lights and other 4S battery pack.
T point Description: plus a normally closed temperature sensor switch can expand the role of temperature protection, need to remove the solder joint next to the 0R resistance.
Note: 3A current above the discharge products, the battery discharge rate to 3C or more.
Magnification calculation formula: 1C magnification of the battery, 2000 capacity is equal to 2AH * 1 = 2A upper limit current. 3C magnification battery, 2000 capacity equal to 2AH * 3 = 6A upper working current.
In the use of the battery will heat is Battery magnification is not applicable, this situation can not be long-term use, the battery will soon be damaged.
