Description
Tips: We can provide wholesale if you need large quantity, please contact us. Thanks.
Feature: Battery charging, overcharge and overdischarge protection circuit, high efficiency boost one. The thumb cap size, compact: about 25X18X7MM, the output voltage, the error of 3%, full SMD technology, ceramic multilayer capacitor microampere static current (measured about 200uA, different output voltage difference, 20uA, not the so-called stand data theory validation), can withstand higher temperature.
Details:
BOOST asynchronous rectifier, different output voltage boost efficiency and different. Between about 80-95%. Standby current: 200uA@3.7V depending on the output voltage, there will be differences The protection circuit is charged to 4.25V, the discharge cut-off is about 2.5V, regardless of the charging time, no matter how many batteries are connected in parallel The charge interface input is MICRO USB, 5V B+ connect the battery positive electrode, B- connect the battery negative electrode, must not be connected, or directly scrapped. There are two indicators, one for the red, one for the blue discharge Charging: resistance current limiting + lithium battery protection circuit overvoltage open circuit, measured charging current below 500MA, the specific value depends on the battery voltage and internal resistance。
