Product Description
XTAR 21700 5000 mAh 3.6 - 3.7 V Li-Ion battery with protective circuit
The XTAR 21700 Li-Ion battery with 5000 mAh is a versatile power cell equipped with an integrated battery management system (BMS). The protective circuit (PCB) protects the battery against overvoltage, undervoltage, short circuit and reverse polarity, making it particularly suitable for torches, laser pointers and other demanding applications. The built-in industrial cell-a Samsung INR21700-50E-was developed for areas such as industry, mobile energy, electromobility and LED technology.
Note: Due to the integrated electronics, the cell is larger than a standard 21700 cell without PCB. Please check the dimensions before purchasing, as it may not be suitable for all applications.
