Lithium-iron phosphate batteries are better than lead-acid batteries.
Lithium iron phosphate batteries (LiFePO4 or LFP), what else is good?
1. Super-long battery life
Battery life, the above lead-acid batteries, long-life lead-acid batteries cycle life in about 300 times, the high is 500 times, and lithium iron phosphate power batteries, cycle life can reach more than 2000 times, the standard charge use, can reach 2000 times. The same quality of lead-acid batteries are mostly 1 to 2 years, while Energizer LiFePO4 batteries portable power stations used under the same conditions, the theoretical life will reach 10 years. Considered together, theoretically 4 or 5 times more economical than lead-acid batteries.
Non-toxic and environmentally friendly
One of the important reasons why lithium batteries are favored by the industry is environmental protection. lithium iron phosphate batteries used in Energizer PPS320 and PPS2000 Power Solar Station are generally considered to be free of any heavy and rare metals (NiMH batteries require rare metals), certified by SGS as non-toxic and non-polluting, in compliance with European RoHS regulations, with an authoritative " Green Battery Certificate".
Charging and use (memory effect)
If the battery is a nickel-cadmium battery, due to the memory of nickel-hydrogen, nickel-cadmium batteries exist, long-term not thoroughly charged and discharged, often under the condition of full not put, easy to leave traces in the battery, the capacity will quickly lower than the rated capacity value, this phenomenon is called the battery memory effect. Battery if the memory of the user's daily charge and discharge amplitude and mode, day after day this pattern is difficult to change, can no longer be a substantial charge and discharge. Lithium iron phosphate batteries do not have this effect, no matter what state the battery is in, can be charged as you go, no need to discharge before charging.
Small size, lightweight, high capacity
General lead-acid battery pack weight of 16-30 kg, larger volume, the same capacity of lithium iron phosphate battery volume is 2/3 of lead-acid batteries, weight is 1/3 of lead-acid batteries. lead-acid batteries to 12V/65AH for example, weighing about 18.5 kg, lithium batteries to 12.8V/63AH for example, weighing about 4.4 kg, lighter weight, smaller volume, lithium batteries than ordinary batteries (lead-acid batteries, etc.) capacity. Therefore, the Energizer 300W 320Wh solar generator weighs 4.1 kg, and the Energizer 2100W 2150Wh solar generator weighs 30 kg, which is more portable than the lead-acid battery.
