High definition 20kw Solar Battery - HUIZHOU RUIDEJIN 280 Ah 12V Energy Storage Lifepo 4 Lithium Batteries 3.2V Rept 280Ah Lifepo4 Battery Cells – Ruidejin

Short Description

3. Third, the cycle life is long. Under the same operating conditions, the cycle life of the lead-acid battery is about 500 times, while the lithium iron phosphate power battery is used according to the standard charging (5 hours rate), and the cycle life can reach 2000 times. Lead-acid batteries of the same quality are “new half a year, old half a year, maintenance and maintenance another half a year”, while lithium iron phosphate batteries are used under the same conditions, and their cycle life is several times longer than lead-acid batteries.

4. Good high temperature performance

The electric heating peak of lithium iron phosphate can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. The working temperature range is wide (-20C–+75C), and the electric heating peak of lithium iron phosphate with high temperature resistance can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.

5. large capacity

It has a larger capacity than ordinary batteries (lead-acid, etc.). It can be known from the capacity density of the battery. The energy density of lead-acid batteries is about 40WH/kg. The mainstream lithium iron phosphate batteries on the market have an energy density of 90WH/kg. kg or more.
