Product Introduction:
This product is suitable for DIY, it should be the smallest and thinnest product with the same function (compared with other similar products much smaller, also thin 0.6mm) is very important for the modification of small electrical equipment. And half hole positioning, easy to fix.
Scope of application:
1. diy lithium battery charging;
2, small electrical magic;
3. Add charging ports to tablets.
Product characteristics:
■ Small volume. It's smaller than its peers.
■5-6V power supply, suitable for single lithium (parallel unlimited), default current 1A.
■ Suitable for all types of 3.7V lithium batteries, including 18650 and accumulator batteries.
■ With overrush and overdischarge protection, overdischarge protection 2.4V, charging cut-off voltage 4.2V/ 4.35V optional!
Function introduction:
When the charging current reaches the final floating charging voltage and drops to 100mA, the charging cycle will be automatically terminated.
▼ When the battery voltage drops below 405V(roughly corresponding to 80% to 90% of the battery capacity), the charging cycle starts again.
When the battery voltage is lower than 2.9V, the battery will be pre-charged with 100mA current.
With protection plate, over voltage protection, over discharge protection, over current protection. Overdischarge protection value: 2.4V; Overcurrent protection value: 4A.
Tip: The first use needs to connect the power supply to activate the protection board!!
Usage:
The connection is marked according to the figure above (the part with the same color is physically connected). Port C input or connection input can be used. The battery cannot be connected in series, but can only be connected in parallel. The thread needs to be welded, the thread should not be too thin,Otherwise it won't work properly. Batteries cannot be reversed.
Product Features：
1. Small volume. Smaller than similar products.
2. 4.5-5.5V power supply, applicable to a single lithium battery (unlimited in parallel), with a maximum of 1.2A. It can be used to stabilize 1A current as required.
3. Applicable to all types of 3.7V lithium batteries, including 18650 and aggregate batteries.
4. With overshoot and over discharge protection, the over discharge protection is 2.9V, and the charging cut-off voltage is 4.2V!
5. When there is no external input voltage, it will automatically switch to the output mode, supporting small current, output 5V, and output about 450mA. If 1a is output, the voltage will be about 4.9V-4.5V according to the power situation.
6. Automatically switch the input and output, and charge the battery when the external voltage is input. Otherwise, when discharging, the charging green light flashes, the full green light stays on, the light does not light when discharging without load, and the blue light is on when discharging with load. Standby power consumption is about 0.8mA.
Product Features:
★ This module uses a very mature charging chip TP4056, the peripheral circuit is simple, good protection performance, high charging precision.
★ This module is completely mechanical automatic processing, all SMT parts manufacturing, each module will be tested before shipping, high reliability.
★ The current of this module can be adjusted by itself. As long as the fixed resistance in the circuit board is changed, the output can be changed to 100mA-1000mA, which is very convenient.
