TP5000 Charging Board Lithium-ion Battery Lithium Iron Phosphate Battery 1A Charging Board 3.6/4.2VItem NO.: TP50003.6V4.2V

TP5000 Charging Board

Features:

The entire version uses precious metal ceramic capacitors, with X7R temperature characteristics, performance, safety, and stability far exceeding tantalum capacitors!

Copper strip 5A high current small volume inductor, fully closed magnetic low loss and low interference!

Single sided machine mounting, overall 4mm ultra-thin, small area with good heat dissipation, and copper exposed on the back for easy installation and heat dissipation

Based on DC-DC voltage reduction, the efficiency is much higher than that of linear charging circuits, and the heat generation is also much smaller. The charging current is 1A, but the input current only needs about 0.7A to be sufficient

Optional lithium iron phosphate battery or regular lithium ion/lithium polymer battery, can be set with just one jumper

Compact size, the size of a dime, 1A charging without additional heat dissipation

Equipped with overheating protection, overheating will automatically reduce the current to prevent burning out

Full page high-precision resistor, full volume 1210 precious metal multilayer ceramic capacitor X7R stable temperature characteristics

Full automatic stop, dual color charging status indicator light
