During the past year, I replaced a lot of batteries at home with a lot of batteries and replaced them with Li-ion batteries. Lantern radios, Led lantern, Hand broom etc …
One of the radio lanterns was a 6v battery and the other one was a 1.5v pen pile. One of the two Li-ion batteries was enough battery power for the Li-ion battery + strike tip serial 1n4007 diode connected to 0.7v voltage loss I made a simple rule with the problem did not make a problem ..
Led flashlight 6v battery 1 Li-ion battery is enough Bleached batteries 3 serial Ni Mh batteries connected 3.6v in it 2 Li-ion pliers connected in parallel
The mini SOT-23-5 I use for the radio and led flashlight charging circuits is able to power 500mA on the MCP73831 is used with an external circuit element. I used the 5V adapter as the power source for the circuits I put into the devices
I also placed the bubble charging circuit in the adapter when the vacuum cleaner is running, if the MCP73831 charging circuit is connected. In the case of MCP73831 R1 resistor is used for current setting, I use 2.2K, 500mA 2K, 240MA 4.2K, 160MA 6.34K, 130MA 7.87K, 100MA 10K capacitors in 10K input and output will be poleless.
MCP73831 Li-ion Battery Charging Circuit Diagram
I needed to use a separate power supply for each of the TP4056 modules. There were a few high power SMPS cards in the box, but it did not save them. I’ve been trying to repair a 1.6A 5V SMPS adapters and have used it on my device, but the SMPS adapters are waiting for a long corner repair. I also used the defective SMPS adapter box for boxing.
I installed the 3-Li-ion battery socket on the box and soldered the modules to the solder modules. I cut the box part of the box to see the charge status and added red mica …
If you have a high-power SMPS adapter, you do not need to use separate power supplies for TP4056 modules.
The current of the TP4056 charge integration can be adjusted. TP4056 modules are usually equipped with “Prog” resistors for the highest output current The TP4056 can be set to 130mA …. 1000mA by changing the resistor connected to Pin 2.
If the power supply in your hand is slightly above the power charging current, for example, if you use a 5V 1A adapter, you must set the TP4056 module current at your hand to 800mA or less, or your adapter may fail or go into protection.
