For the rechargeable (generally refers to the lithium battery) from the protection of the integrated circuit board. Lithium battery (rechargeable type) so need protection. As the lithium battery itself determines the material itself can not be overcharge, over discharge, overcurrent, short circuit and ultra-high temperature charge and discharge, so lithium battery lithium components will always follow a protective resistor with a sampling resistor and a current fuse. Note: Please allow 1-5mm errors due to manual measurement. Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.

Precautions:

Strictly according to the diagram wiring: 0V(B-)3.7V(B1)7.4V(B2)11.1V(B+), Do not deliberately short circuit. After the line is connected, Need to charge first, then have output. When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteries and then use. Do not mix the good battery and the battery. The capacity of the battery internal resistance is closer will be better. Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buying Note: Due to different producing batches, product details might be a little different. If you minding the difference, please buy it carefully. Please allow 1-5mm differs due to manual measurement.
