Description
-
100% depth of discharge & 10-year lifespan
Power Queen’s 12V 300Ah LiFePO4 battery offers over 4000 cycles and a lifespan of 10 years. In comparison, lead acid batteries only offer 200-500 cycles and a lifespan of 3-5 years. Energy from 1 x 12V 300Ah LiFePO4 battery = 3 x 12V 200Ah AGM batteries connected in parallel.
-
⚡ Powerful core and sustained performance
The Power Queen 12V 300Ah lithium battery consists of 8 automotive-grade cells. It is high-density, stable, safe for daily use and environmentally friendly. The 200A BMS allows you to connect more devices and supports a maximum charging power of 2560W, making life more convenient.
-
High energy density
Lighter and more powerful than conventional lead-acid batteries with three times higher energy density.
-
100% capacity
Unlike lead-acid batteries with 50-60% capacity, our LiFePO4 battery offers 100% usable capacity.
-
Intelligent BMS
Integrated 200A BMS protects against overcharge, overdischarge, overcurrent, overtemperature and short circuit.
-
Fast full charge
With a 14.6V 60A charger, a full charge takes only 5 hours. A 14.6V 40A LiFePO4 charger is also a good choice.
-
Environmentally friendly energy & Save 1/2 electricity fees
Compared to mains power, lithium batteries can save 50% of energy costs. Compared to using lead-acid batteries, the energy saving is 12% – 27%. The monthly self-discharge is about 3% for lithium batteries and about 15-30% for lead-acid batteries.
