12V 50Ah Premium LiFePO4 Lithium Battery Deep Cycle 691.2Wh BMS for Camper Boat
Item Description
Why Choose LiFePo4 Li-ion Battery?
•【Large Capacity】
The monomer can be made into 5Ah~1000Ah (1Ah=1000mAh), while the lead-acid battery 2V monomer is usually 100Ah~150Ah, with a small variation range.
• 【Light Weight】
The same capacity of lithium iron phosphate ion battery volume is 2/3 of the volume of lead-acid batteries, the weight of the latter is 1/3.
• 【Fast Charging Capability】
Lithium iron phosphate ion battery start current up to 2C, to achieve a large rate of charging; lead-acid battery current is generally required to be between 0.1C ~ 0.2C, can not reach fast charging performance.
• 【Environmental Protection】
Lead-acid batteries have a large amount of heavy metal lead, waste liquid, while lithium iron phosphate ion batteries do not contain any heavy metals, in the production and use of pollution-free.
• 【High cost performance】
Although lead-acid batteries due to its cheap materials, the acquisition cost to be lower than lithium iron phosphate ion batteries, but in the service life and routine maintenance of the economy is lower than lithium iron phosphate ion batteries. Practical application results show that: lithium-ion iron phosphate batteries are more than four times the cost performance of lead-acid batteries.
·【Long life】
Lithium-ion iron phosphate battery cycle times in more than 2000 times, the lead-acid battery cycle times are usually only about 300 ~ 350 times.
Features ▷Lithium iron phosphate core, mature technology, high safety, 100% DOD for normal use,Charge and discharge for more than 2000 cycles ▷Perfect replacement for lead-acid batteries, 40-50% lighter and maintenance-free ▷Built-in lithium protection against overcharge, overdischarge, overcurrent and overtemperature ▷Wide operating temperature range: -20°C to 60°C ▷Support for series use (subject to technical guidance from the manufacturer) Application Scenarios ▷ Solar street lights and lighting systems ▷ Electric two-wheelers, three-wheelers, low-speed vehicles ▷ Sightseeing vehicles, golf carts ▷ Energy storage systems for photovoltaic, wind, hydroelectric, household etc. ▷ UPS back-up power supply |  |
