Product Description

Manufacturers Custom Wireless Camera Battery 6V 4Ah


1. Lightweight and compact: For battery packs with the same voltage and capacity, the volumetric mass of lithium iron phosphate batteries is only about 1/3 of that of lead-acid batteries

2. Ultra-long life: the cycle life of long-life lead-acid batteries is about 300 times; while the cycle life of lithium iron phosphate batteries is more than 2000 times

3. Safe to use: Lithium iron phosphate battery completely solves the safety hazards of traditional lithium batteries, and will not explode or catch fire in the most extreme test environment.

4. Stable discharge characteristics: at the same temperature, using different rates of discharge current, its discharge point output characteristics are very stable

5. Good start-up at low temperature: Lithium iron phosphate battery can start normally at -20℃, while traditional batteries can only start normally at -10℃

6. Green and environmental protection: Lithium iron phosphate battery does not contain any heavy metals and rare elements, no matter in the process of production or use, it is non-toxic and non-polluting

7. Long storage time and small self-discharge: monthly self-discharge of lithium iron phosphate battery is only 2~3%, and monthly self-discharge of lead-acid battery is 4~5%

8. Accepts high current and fast charge and discharge: can receive 3C charge and discharge current
