cycle life of the battery. |
This is the latest version ---LF280K, 6000 cycles. In the same battery pack, we do not recommend mixing "N" series and "K" series.
Application areas
1. Motorhomes, caravans, electric bicycles/motorcycles/scooters,
golf carts/baby strollers,
2. Solar energy system, wind energy system, household energy
storage system, backup system and UPS
3. Modal equipment, consumer electronics, power tools and engine
starting batteries,
4. Flashlights, LED emergency lights, solar street lights,
decorative lighting, yachts, lawn mowers, etc.
Advantages of lithium batteries: (the reason why lithium batteries are used instead of lead-acid batteries)
1. Longer cycle life than lead-acid batteries
-At least 2000 times-8000 times 40% DOD
2. Half the weight of lead-acid batteries
3. Fast charge-charge to 99% in 2.5 hours, while lead-acid batteries require up to 13 hours.
4. Can accept high charging rate (100A)
5. No maintenance required
6. No battery memory
7. Almost no temperature derating affects 8.95% energy efficiency
