Product Description
Blue Carbon 12Volt Deep Cycle Lithium ion Batteries Pack 12V 300Ah Lifepo4 Battery

Product Advantage
Small Size & Light Weight
1.Blue Carbon products use lithium iron phosphate batteries, the depth of discharge can reach 80%, and the depth of discharge of lead-acid batteries does not exceed 50%. which means 25-50% more usable capacity compared to the same size lead-acid battery, but typically 1/3 weight.
2.The circuit is designed so that the charging current will not exceed 0.2C, which ensures normal operation
even under the climate conditions of Hailar (minimum daily average temperature -27°C).
Multiple Protection BMS
1.The lithium battery features an elegant BMS that provides multiple protections to keep the battery
operating safely:
2.Overcharge protection function -Overdischarge protection function
3.Over current protection function -Over voltage protection function
4.Temperature protection function -Short circuit protection function

Long Cycle Life
1. The durability of LiFePO4 Battery is powerful and consumption is slow. The time of charging and discharging is more than 2000times. After 2000times circulation, the capacity of the battery is still more than 80%.
2.No matter the LiFePO4 Battery is in which conditions, it can be charged and discharged whenever you like, no need to discharge totally then charge for it. 3.LiFePO4 battery passed the strict safety testing, with higher safety performance.
Wide Application
1.For no city power areas, the battery pack can be charged by solar panels and used for night lighting;  2.For the areas that city power is expensive, the battery pack can be charged during the electricity valley value period, and used at the peak power period;  3.For the areas which power off from time to time, the battery pack can be used as UPS, to avoid information loss caused by sudden power outage.  4.The battery pack is applicable to commercial lighting, industrial lighting, home lighting, outdoor lighting, camping tourism, farming, planting, the night market stalls, etc.
