The TP4056 1A Li-Ion Battery Charging Board with Type C and Current Protection is a compact solution for charging single-cell 3.7V Li-Ion batteries (1Ah or higher) like 16550 cells without built-in protection. Featuring the TP4056 charger IC and DW01 protection IC, it provides 1A charging with automatic cutoff when complete.

Additionally, the protection IC disconnects the load if the battery voltage falls below 2.4V, preventing excessive discharge. It also offers protection against over-voltage and reverse polarity, where it may self-destruct to protect the battery. Ensure proper connections during the first use.
