Features:Three series of lithium battery protection board.Automatically cancel protection after protection conditions restore. With function of overcharge protection, over discharge protection, short circuit protection, over-current protection.Suitable for lithium battery pack of 11.1V, 12V, 12.6V.Fine workmanship and durable.Quiescent current 30uA, so power consumption is small.Specifications:Model: 1#:HX-3S-01, 2#:HX-3S-FL10-A Size: #1: 50 * 16 * 1.0mm/1.97 * 0.63 * 0.04inch#2: 53 * 17 * 4.0mm/2.09 * 0.67 * 0.16inchMaximum operating current: 6-8AMaximum transient current: #1: 9-10A, #2:10-13AQuiescent current: 30uAInternal resistance: 100mWorking temperature: -40~+50Storage condition: -40~ +80Effective life: >30000hShort circuit protection: Yes, delayed self recoveryThe component included:#1: 1 pcs S-8254AA protection chip, 4 pcs AO4407#2: 1 pcs 2110-cb protection chip, 2 pcs AOD472Notes:1. Higher than 3A current discharge product, the discharge rate of battery discharge is above 3C.2.Multiplier calculation formula: 1C battery, 2000 capacity is equal to 2AH * 1 = 2A maximum working current.3C ratio battery, 2000 capacity is equal to 2AH * 3 = 6Amaximumworking current.3.In the process of use, if the battery heat, the battery power is not applicable. This situation cannot be used for a long time.Otherwise, the battery will soon be damaged.Package Included:1 x PCB Protection Board(have assembled)
