Product Advantages
Why Choose Lithium Iron Phosphate (LifePO4)?
1. Super Long Life
The cycle life of the LifePO4 battery is about 3000-5000 times. Low self-consumption, and long storage time.
2. Be Safe
The main component of lithium iron phosphate battery is iron, It is not easy to catch fire and explode.
3. High Energy Density and Low Weight
The same volume of lithium iron LifePO4 battery has 50% more capacity than lead-acid battery, but 70% less weight.
4.High-temperature Performance
LifePO4 peak electrical heat up to 350 ℃ ~ 500 ℃. Working temperature range in -20 ℃ ~ 80 ℃, But lead-acid is -20℃~50℃.
5. Save Postage
The same volume of LifePO4 battery weighs 70% less than lead-acid. Save your shipping costs.
6. Environmental Friendly
Non-toxic and non-polluting, in line with European RoHS regulations, used batteries can be recycled and reused.
