3S 15A Li ion Lithium Battery 18650 Charger Protection Board
The typical lifespan for a lithium battery is two to three years. A good rule of thumb is that once it can hold only 70-80% of its original energy storage, the battery should be replaced.
1. More than 3A current discharge products rate is more than 3C Ratio calculation formula.
2. 1C rate of the battery, 2000 capacity is equal to 2AH 1 2A maximum working current.
3. 3C ratio battery
4. 2000 capacity is equal to 2AH * 3 = 6A maximum working current.
5. In use battery heats is ratio is not applicable to
6. This kind of situate can’t use for a long time. In accordance with the diagram wiring 0 V, 3. 7V (b-) (B1) (B2), 11. 1 V , 7.4 V ( B + ) don’t deliberately short circuit
1. After connected line need to recharge.
2. Just can have output
3. 3 series battery, please make sure that each set of battery voltage, if not, please separate with each set of batteries in series. Discharge test , the battery voltage drops quickly is a bad battery
4. Don’t put the good cells and in bad! Three groups of battery capacity / internal resistance as close as possible! ( 2 + 1 good battery , the use effect of poor battery = the use effect of three bad battery )
