Product Description:
3 string 12.6V 40A lithium battery protection board
Hardware preparation:
Prepare 3S 12.6V 40A lithium battery protection module, battery, power supply, high power load resistor
The figure below shows the module discharge diagram. The battery is 3 strings. The connected battery needs to meet the 40A discharge current. It can be realized by paralleling the battery or purchasing a battery with a large discharge current. For example, if the battery is 2000mAH and the discharge multiple is 10C, then only 3 strings of 2 are needed and the discharge current is 40A.
The figure below shows the battery charging diagram. The charging voltage is DC12.6V~13.6V. The charging current depends on the battery connected, and the maximum is no more than 20A. The module has a balanced charging path, and the equalization function works only when the battery performance is not much different.
4 string 14.8V 16.8V 40A lithium battery protection board
The figure below shows the module discharge diagram. The battery is 4 strings. The connected battery needs to meet the 40A discharge current. It can be realized by paralleling the battery or purchasing a battery with a large discharge current. For example, the battery 2000mAH, the discharge multiple 10C, then only need 4 series 2 and the maximum current can reach the discharge current 40A, stable discharge requires 4 strings 4 and can be, and need to pay attention to heat dissipation, the discharge battery power will drop rapidly.
The picture below shows the battery charging diagram, 4 series of batteries, the actual full charge, voltage 16.8V, charging voltage DC17V-18V, charging current depends on the battery connected, the maximum does not exceed 20A.
