TP5000 rechargeable board lithium ion battery lithium iron phosphate battery 1A charging board

Lithium ion battery only need to connect a 5V power supply, output B + B-connected battery can be. Charging red light, full of self-stop, charging green light finished. For lithium iron phosphate battery 3.6V, just soldering iron solder between the two solder pad can be. If you want to change back to charge 4.2V lithium battery, solder pad can be used to solder back. In switch buck mode, the efficiency is higher than the linear charging circuit, heat is also much smaller. Charging current 1A, in the constant current full charge to maintain 1A. With overheating protection, overheating will automatically reduce the current to prevent burnout. No additional heat dissipation, reducing the impact of heat on the charging current. Lithium ion battery reduces the charging time. Optional lithium-ion lithium polymer battery or lithium iron phosphate battery, just a jumper can change the settings.
