Review on CHENBO 10 Pcs 5V Micro USB 1A 18650 TP4056 Lithium Battery Charging Board: Efficient Protection Charger Module by Christopher Shavers
Perfect for completing my project!
Compact size, easy to read labels and good price, not sure what more could you ask for. This was intended to equip the ESP32 board with a motion sensor so that it could discharge when power is lost or interrupted. Soldered 5V wires, battery and output with no problems. The battery output leads were about 4v when first checked, then 4.1, then 4.5, then 4.2v, tested about every half hour then stayed steady at 4.2v. I'll update if anything else appears, but if He doesn't have a short life, that's a good option.
- Connect the battery to B+B- into the mobile phone USB charger, the red indicator is charging, the green indicator is full.
- I vaguely remember
