The LG INR21700-M52VT is a high-capacity lithium-ion cell in the 21700 format, designed to offer significant autonomy while maintaining a continuous discharge current of up to 15 A. Thanks to its INR (NMC) chemistry, it offers an excellent compromise between capacity, thermal stability, safety, and service life.
With its 5200 mAh capacity, this cell is ideal for custom batteries designed for electric bikes, high-capacity power banks, powerful lamps, portable energy systems, or technical projects requiring extended battery life.
This version is supplied without built-in protection (unprotected), making it suitable for systems equipped with an external BMS or a suitable management circuit.
