Product description: This is a new type of integrated charging and discharging charging boost power board module, which not only solves the limitation of only charging or only discharging, but also has a compact and lightweight design, is easy to install and use, and is worthy of your choice

scope of use
Lithium battery charging DIY
Small electrical appliance modification
The tablet computer is equipped with a charging port
1: Small volume. Smaller than congeneric products
2:5-6V power supply, suitable for single lithium battery (unlimited parallel connection), default 1A current
3: Suitable for all types of 3.7V lithium batteries, including 18650 and aggregate batteries
4: With overshoot and overdischarge protection, overdischarge protection 2.4V, charging cutoff voltage 4.2V/4.35V

How to use
C port compatible with direct input or wiring input. The batteries cannot be connected in series, only parallel Connected. The wire needs to be welded, and the wire cannot be too thin, otherwise it will not work properly. Electricity Pools cannot be reversed

Function introduction
When the charging current drops to 100mA after reaching the final float voltage, the Automatic termination of the charging cycle
* When the battery voltage drops to 4.05V (approximately corresponding to 80% to 90% of the battery capacity) After that, the charging cycle starts again
When the battery voltage is lower than 2.9V, 100mA of current will be applied to the battery Pre-charge
* With protection plate, over-voltage protection, over-discharge protection, over-current protection. Over-discharge protection value : 2.4V; overcurrent protection value: 4A

Attention:
* The first use requires a power activation protection board
1. The battery cannot be connected in reverse
2. The battery terminal voltage cannot exceed the purchased voltage
3. The battery cannot be connected in series, only in parallel, and it will burn in series
