That's 12 amps.
The capacity of a single 18650 lithium battery is generally 2 Ah. When using 6 parallel, 6 single 18650 batteries are connected in parallel. Its capacity is 6×2 Ampere-hours equal to 12 Ampere-hours. When 6 sets of 12Ah lithium batteries are connected in series, only the voltage changes, but the battery capacity does not change. The capacity of this battery is therefore still 12 Ah.
A battery refers to a cup, tank or other container or part of a composite container that contains an electrolyte solution and metal electrodes to generate electric current. It is a device capable of converting chemical energy into electrical energy. .
What is the charging voltage of a 12.6 volt 3-string lithium battery with a cover plate?
Is each cell 2000 mAh? If this is the case, the voltageshould be 3.6 to 3.7 V, take 3.7 V.
When 5 are combined, the capacity is 5*2000=10000mAh=10Ah, and the voltage remains unchanged;
And then combine 5. There are three battery strings in the rear battery, the voltage is 3*3.7=11.1V, the capacity remains unchanged, it is still 10AH
Finally, the charger voltage is selected to be 11.5-12V, and the current is selected as 0.3*10= according to slow charging 0.3C 3A, if selected according to the 3C fast charging current, it is 3*10=30A
For reference.
The charging voltage of the 3 string lithium battery is 12.6V. If the green light on the charger appears and the charger is unplugged and the battery voltage does not reach not 12.6*98%, it means your charger 1) The charger is The output line is too small and the voltage drop is large, causing the main chip of the charger to measure the voltage deviation of the battery 2) Thecharger is not in constant current and constant voltage mode 3) Charger is rotating; the light current is too high.
