The 12V lithium battery must have at least 3 18650 batteries, and if you customize the 12V large-capacity lithium battery, you need to connect more (Section 1-3). The rated voltage of 18650 was 3.7 volts, but we directly measured the voltage of the 18650 battery to 4.2 volts. Many people are tangled, do you use 3 sections 18650 and 4 sections 18650?
18650 is a type of battery, a cylindrical lithium battery with 18 mm long 65 mm. It usually has a rated voltage of 3.7 volts and saturated voltage of 4.2 volts. It usually uses 2000 mAh, 2200 mAh, 2600 mAh, 3400 mAh, etc. Essence
The rated voltage of the 18650 lithium battery is 3.7 volt, and the charging volume is 4.2 volts. The manufacturing of the battery pack is based on the rated voltage, 12/3.7 = 3.24. In this way, 3 verses of 18650 lithium batteries can generate 12 V battery packs in series
When manufacturing large -capacity battery packs, the capacity of 18,650 battery packs must be calculated. For example, a 18650 battery, which has a capacity of 2000 mAh, can make a 12V20AH battery pack.
20 AH requires 10 batteries to get the required power in parallel. In the end, to obtain a voltage of 12 V, 3 series are required. The last battery pack is a 10-3 string battery pack. A total of 30 knots 18650 battery packs are required.
