شارژر میکرو USB باتری های لیتیومی 5 ولت 1 آمپر به همراه محافظ
Micro USB 5V 1A Lithium Li-ion Battery Charge Charging Module + Protection Board, PCB Circuit Module Cas 18650 Battery 4.2v DIY
Features:
1. Charge the module Linear charging.
2. Current- 1A adjustable.
3. Charge precision- 1.5%.
4. Input voltage- 4.5V-5.5V.
5. Full charge voltage- 4.2V.
6. Led indicator- red is charging Green is full charged.
7. Interface- micro USB input.
8. Work temperature- -10 to +85.
9. Inversed polarity- NO.
10.Size- small about 26mm x 17mm
With MICRO USB femal socketcan be connect directly with mobile phone charger for charging the lithium battery. Input Voltage5V, Cut-off charging voltage 4.2V +/- 1% Maximum charging current 1000mA Battery over-discharge protection voltage 2.5V Battery over-discharge protection current 3A
NOTE:
1. Ampere meter can only be connected to 5V input end of the module.
2. It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAh, current of 400 is enough.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. If the input voltage is too high, like 5.2V, the current will be less than 1000mA, it is normal. It is protection function, auto-Subtract the charging current to avoid burn damage to the chip.
6. NO Reveral polarity.
How to use:
1. Micro USB is connected to the phone charger
2. Li-Ion battery pole is connected to B + and B-
3. Electrical loads such as lights, toys, mobile phones, etc., connected to the OUT + and out-, so that over current protection and over-discharge function. When bypassed directly to B + and B- The protection function will not work and could potentially damage the Li-Ion battery.
Tips: The current recommended input cas about 37% of the battery capacity. When the battery was about to be charged with a capacity of 1000mAh, charge current 400mA input is enough.
