    DISCLAIMER: This item is a sophisticated electronic controller. You will need skill and knowledge to install it and use it. You will need to have done research, some available on YouTube - search "eBike School" and "Jehu Garcia" by example to find out what a bms is, what it does and especially how to install it. Wiring diagrams and how to use the bms are found on this listing. It will not be possible to return this item once opened and used, but most especially due to use or damge caused by negligence or lack of knowledge.
    This bms is for a Lithium-ion battery. Not suitable for a LiFePO4 battery

3 Series 18650 battery
11.1V (Li-ion 18650 or li-ion battery rated voltage)
12.6V (Li-ion battery full charge voltage)
10.8V ( Lipo battery pack rated voltage)
The lithium battery protection board is not included the welding tabs.
 
BMS activate method : Use 12.6V Li-ion  charger to charge it.
 
NOTE:
1) This board is not suitable for high power electronic tools. If intending to use for screwdriver, drill or electric bike and 1W LED, please don't buy this. You need a higher powered BMS which we have. See other items

Balancer is a Auxiliary function, The balancing means when the battery charging,each series battery need with the same voltage.when ONE cell voltage get 4.2V, and the other cells not, the first cell voltage will discharge to wait for the other cells rising to the same level.

Note: battery internal resistance differences within 5 milliohm, voltage within 0.03 V voltage, capacity vary within 50 ma

Features:

1) high-accuracy voltage detection circuit;

2) terminal of the charger using high voltage device;

3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit);

4) MOS transistor can control the battery charge and discharge;

5) low standby current consumption.
