# 1. Overview #
Powerbank based on FP6277 boost converter with 5V and 3.3V output up to 3A. Choose a good 18650 Li-Ion battery with a low internal resistance which is capable of delivering up to 7A!
This is a almost exact copy of the TP4056. The only difference is that this board has a better protection IC. Basicly it has a better protection sistem.
The TP4056 module is made for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. In addition to safely charging a lithium battery the module also provides necessary protection required by...

Li-Ion battery charger, protector and 5V/3A booster. Use unprotected Li-Ion batteries with low internal resistance which are rated for a discharge current of at least 7A! Connect the battery with short wires of 20AWG or thicker! Attach a heatsink on the back side of the PCB when drawing more than 2A of current continuously! Use a slide switch that can withstand a current of 6A!
Li-Ion battery charger, protector and 5V/2A booster. Use unprotected Li-Ion batteries which are rated for a discharge current of at least 5A !
TP4056 18650 Li-Ion Battery Charger, this is for charging four 18650 batteries at once. Circuit can be used for just one module, just create a new PCB.
Rx_3 set to 2K to limit the charge current to 580mA.

# 18650 Charger & Regulator
Low-cost 4-cell 18650 charger use TP4056 charger modules, each output of the TP4056 modules can be connected to MT3608 and/or LDO (HT73xx/HT78xx) to get a regulated voltage.
Voltage and current checkpoints are provided to easily monitor the voltage and current of each battery, a 2.45mm slide switch can be soldered on the current checkpoint.
Furthermore, it is fairly...
This is the second version of my TP4056 based lithium battery charger module.
In v1.xx i used a linear voltage regulator (LM7805CV) which got very hot and limited the potential of the module a lot.
In v2.10 i replaced LM7805 with a switching counterpart (XL2011) which resolves most of the input issues allowing for a full range of 5V (via USB) and from 8-45V via the screw terminal or DC-Jack.

*Sorry for my following english language (En français plus bas)*
- Energy self-sufficient, solar panel charge battery with TP4056 and systeme is low-power managment
- Check luminosity with solar panel and open or close the door (no RTC)
- Geared-Motor AC is drived with specific H MOSFET bridge IC
