TP5100 Single 4.2V / Dual 8.4V 2A Lithium Battery Charging Board Review Test Tutorial
What is TP5100?
The TP5100 is a single lithium battery charge management module with a step-down voltage of 8.4V/4.2V. It has over current, under-voltage, and short circuit safety built-in. It also protects against overheating and reverse battery shutdown.

What is TP4056?
The TP4056 chip is a single-cell lithium-ion battery charger that protects the cell against overcharging and undercharging. It features two status outputs, one for charging in progress and the other for charging completed. It also features a 1A charging current that can be programmed.
Because the functional input voltage range is 4V to 8V, you can charge batteries straight from a USB port. However, keep in mind that a USB port's maximum current is 500mA.

TP5100 vs TP4056: Conclusion
Both the TP5100 and the TP4056 are charging and protection modules that can do their jobs rather well. However, the TP5100 module outperforms the TP4056 module in terms of power and functionality, while the TP4056 module outperforms the TP5100 module in terms of cost and availability.
What is TP4056 used for?
The TP4056 is a complete constant-current/constant-voltage linear charger for single-cell lithium-ion batteries. Its SOP package and low external component count make the TP4056 ideally suited for portable applications.
How do I use the TP4056 charging module?
The TP4056 module is powered by a 5V supply from a micro USB cable or the IN+ and IN- solder pads. For the charger to correctly charge a battery connected at the output terminals, a current of at least 1A is necessary. Connect the B+ and B- connections to the cell you want to charge.
Does TP4056 have protection?
The TP4056 chip is a lithium-Ion battery charger for a single cell battery, protecting the cell from over and undercharging. It has two status outputs indicating charging in progress and charging complete.
Can I use TP4056 to charge LiPo?
Single-chip solutions are now widely available for Li-Po battery charging.
Does TP4056 have protection?
The TP4056 chip is a lithium-Ion battery charger for a single cell battery, protecting the cell from over and undercharging. It has two status outputs indicating charging in progress and charging complete.
