ITEM NAME:4S 100A 12.8V w/balance LiFePo4 LiFe 18650 battery cell BMS protection PCB bo ME 100% Brand New and High Quality 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. Size: 70 * 60* 8.5mm Overpressure voltage range: 2.5V ± 0.05V Overcharge voltage range: 4.25V ± 0.05v Upper working current: 100A Upper limit instantaneous current: 120A Quiescent current: less than 30uA Internal resistance: less than 150mA Charging voltage : 16.8V Charging current : 10A(max) Short circuit protection: protection, delay self-recovery. Operating temperature: -20 -- +80 ℃ 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. B- = Battery negative P- = Output/discharge negative C- = Charger negative C+ = Charger positive P+ = it equal to Battery positive = discharge positive Include: 1 x 4S 100A 12.8V w/balance LiFePo4 LiFe 18650 battery cell BMS protection PCB board.This product is 4 string 12.8V LiFePo4 Lithium iron phosphate battery power protection board. With heat sink. Upper working current: 100A. Products with 10 MOS tube, powerful cooling aluminum, continuous current limit of 100A.
