2S Applicable scope: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions) Product Size: 45*15*3.4mm (Standard), 48*20*3.4mm (Balancing) Charging voltage: 8.4V - 9.0V Continuous discharge current (upper limit): 20A (If the cooling environment is not good, reduce the load current use) Continuous charge current (upper limit): 10A Standard Edition: Suitable for starting drills with currents up to 25A below 50W, or resistive loads below 168W. 3S 3S 12.6V lithium battery balancer board Scope: Nominal voltage of 3.7V, full of voltage of 4.2V lithium battery (including 18650,26650, polymer lithium battery) Applicable voltage: 12.6V Product Size: 15 * 30 (40,50) * 2.4mm Balancer current: 100mA, suitable for 2000-4000mAh battery pack Note 1: This product can not replace the use of lithium battery protection board (no overcharge protection and over discharge protection) ; works is: the first full of a single battery discharge, waiting for other batteries filled. Note 2: strictly according to map wiring, then the wrong line may lead to burning board; balance plate work when the heat is large, please isolate the battery pack. Note 3: This product is used in parallel with the common lithium battery protection board, can achieve balanced charging function. Note 4: If the battery capacity internal resistance difference is too large, there will be a long time to balance or can not complete the balance of the situation, it is recommended to re-match the battery pack. 4S Description: Scope: Nominal voltage of 3.7V, full of voltage of 4.2V lithium battery (including 18650,26650, polymer lithium battery) Product Size: 20 * 30 (40,50) * 2.4mm Product weight: 3g Applicable voltage: 16.8V Balancer current: 100mA, suitable for 2000-4000mAh battery pack Note 1: This product can not replace the use of lithium battery protection board (no overcharge protection and over discharge protection) ; works is: the first full of a single battery discharge, waiting for other batteries filled.
