Model Number : lithium battery charging board 1A 3.7V4.2V charger module
Type : Module
Origin : Mainland China
Condition : New
atures:1.Use high-quality materials with guaranteed quality2.Ultra small volume, smaller than similar products3.Easy to use, with reverse connection protection at the battery end, the battery will not damage the charging module if reversed4.Stable performance, product with impulse over discharge protection, over discharge protection 2.4V5.Wide application range, suitable for various types of 3.7V lithium batteries, including 18650 and collective five batteries
Parameters:5-6V power supply, suitable for single cell lithium batteries (unlimited in parallel), default 1A currentWhen the charging current drops to 100mA after reaching the final float charging voltage, the charging cycle will automatically terminate.When the battery voltage drops below 405V (roughly corresponding to 80% to 90% of the battery capacity), the charging cycle resumes.When the battery voltage is below 2.9V, the battery will be pre charged with a current of 100mA.Equipped with protective plate, overvoltage protection, overvoltage protection, overcurrent protection. Overdischarge protection value: 2.4; Overcurrent protection value: 4A.Reminder: For initial use, it is necessary to connect the power supply to activate the protective board!!
Usage:According to the above icon, identify the wiring (the parts with the same color are physically connected), either the C-port input or the wiring input can be used. The battery cannot be connected in series, but can only be connected in parallel. The wire needs to be welded and cannot be too thin, otherwise it will not work properly. The battery cannot be connected in reverse.
