4 Series 40A 18650 Lithium Battery Protection Board 14.8V 16.8V with Balance for Drill Motor Lipo Cell Module
The Successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 cannot start the drill!!)
Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit.
4 Series 40A 18650 Lithium Battery Protection Board 14.8V 16.8V with Balance for Drill Motor Lipo Cell Module
This product is a 4 Series 40A 18650 Lithium Battery Protection Board with Balance for 14.8V to 16.8V batteries. It is suitable for lithium batteries with a nominal voltage of 3.6V or 3.7V, such as 18650, 26650, or polymer lithium batteries. can charge the batteries with a voltage range of 16.8V to 18.1V and a continuous charge current of up to 20A. It can also discharge the batteries with a continuous current of 40A and a balanced current of 100mA.18650 Lithium Battery Protection Board has an auto-recovery function and uses 10 low-resistance MOS tubes. It is ideal for electric drills, sprayers, LED lights, or low-power inverters with a starting current below 80A and a power below 135W (with balance). It has a compact size and can be easily installed on the battery pack itself.
Note:
This product is a protection board with balance for 4 Series 40A 18650 lithium batteries. It works with lithium batteries that have a nominal voltage of 3.6V or 3.7V, such as 18650, 26650, or polymer types. It can charge the batteries at a voltage between 16.8V and 18.1V and a maximum current of 20A. It can also discharge the batteries at a maximum current of 40A and a balanced current of 100mA. It has a self-recovery feature and uses 10 low-resistance MOS tubes. It is suitable for electric drills, sprayers, LED lights, or low-power inverters that have a starting current less than 80A and a power less than 135W (with balance). It has a small size and can be easily attached to the battery pack itself.
Features:
This is a lithium battery protection board with four strings and 16.8V 40A. It has an auto recovery function.
It can be used with lithium batteries that have a nominal voltage of 3.6V or 3.7V, such as 18650, 26650, or polymer lithium batteries.
The product weight is 9.3g for the standard or enhanced version, and 10.3g for the balanced version.
The charging voltage range is 16.8V to 18.1V. The maximum continuous discharge current is 40A, but it should be reduced if the cooling environment is poor.
The maximum continuous charge current is 20A.
The balanced version is suitable for drills with a starting current below 80A and a power below 135W.
