Aug 1, 2025 · Features of the Product: 72V 40AH Samsung 21700-50S Cells Lithium Battery with 6A Charger 5C High Discharge Rate Cell ANTBMS 200A support Bluetooth APP Battery Size:
A 72V 40Ah lithium battery is a powerful lithium battery with a 72V voltage rating and a 40Ah capacity. Using a single 72V system is more efficient than connecting six 12V batteries in a series, saving space and contributing significantly less weight to your devices. On top of that, 72V 40Ah lithium batteries are popular for the following advantages:
The 72V 100AH Lithium-Ion Battery provides high safety through circular cells in Lithium Phosphate technology. 72V lithium-ion batteries are supposed to be a cost-effective replacement for lead-acid batteries, with a quadruple energy density for the same weight and size.
A 21700 battery is a high-capacity, rechargeable lithium-ion cell designed for superior energy efficiency and performance. With a standard size of 21mm in diameter and 70mm in length, these batteries were developed as a next-generation improvement over 18650 cells, offering increased power output, extended runtime, and higher energy density.
Protected 21700 Batteries: Feature an integrated protection circuit to prevent overcharging, over-discharging, and short circuits. These are slightly longer than standard 21700 cells. Unprotected 21700 Batteries: Designed for battery packs or high-performance applications where external battery management systems (BMS) handle protection.
With a standard size of 21mm in diameter and 70mm in length, these batteries were developed as a next-generation improvement over 18650 cells, offering increased power output, extended runtime, and higher energy density. They are widely used in electric vehicles, industrial equipment, flashlights, and renewable energy storage.
Capacity: Ranges from 3000mAh to 5000mAh, depending on the chemistry and application. Discharge Rate (CDR): High-drain cells available with 30A, 40A, or even higher CDR ratings for demanding power needs. Cycle Life: Designed to last 500 to 1500+ charge cycles, based on proper usage and maintenance.
