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: Type(Optional): #1(9-10A), #2(10-13A) 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 * 0.16inch Over voltage range: 4.25-4.35v0.05v Over discharge voltage range: 2.3-3.0v0.05v Maximum operating current: 6-8A Maximum transient current: #1: 9-10A, #2:10-13A Quiescent current: 30uA Internal resistance: 100m Charging voltage: 12.6v - 13V Working temperature: -40~+50 Storage condition: -40~ +80 Effective life: >30000h Short circuit protection: Yes, delayed self recovery The component included: #1: 1 pcs S-8254AA protection chip, 4 pcs AO4407 #2: 1 pcs 2110-cb protection chip, 2 pcs AOD472 Notes: 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)
