Which battery is most suitable for solar energy storage?

1,Useful capacity:
In contrast to lead-acid batteries, a LiFePO4 battery can use more than 100% of the nominal size. If you take a 100 Ah battery, you can actually only use 30 to 50 Ah of the capacity with lead-acid, while this is more than 100 Ah with a LiFePO4.
2,Longer longer cycle life:
Research has shown that 2000 to 5000 cycles can be expected from a lithium lifepo4 battery. These are theoretical results, but recent measurements show that this type of cell has more than 75% of its capacity after 2000 cycles.A lead-acid battery, on the other hand, will fail after only 300-500 cycles, with particular attention to maintenance and proper use.
3,Fast and efficient loading:
A 100% capacity charge can be done very quickly. Lead batteries require an absorption phase to load the last 20% of the capacity. If the charger is powerful enough, you can charge the LiFePO4 battery extremely quickly. Even within 30 minutes.If the battery is regularly not fully charged, this is not a problem. Unlike a lead battery, the Lithium will have no damage. This takes away many of the concerns that people usually have about the battery and makes it very flexible.
4,Little lost energy:
They charge with an efficiency of almost 100% compared to 85% for the vast majority of lead batteries. This efficiency is especially important when using solar cells and energy backup.
Climate resistance:
Both lead-acid and LiFePO4 lose capacity in cold environments. With the LiFePO4, however, this loss is minimal. For example, it has an ability of 80% at a temperature of -20˚C, whereas this is only 30% with an AGM lead battery. LiFePO4 is also the logical choice for use in extreme cold and heat, hence the high demand for these batteries in the professional world.
5,Easier to install:
Can be mounted in any position and, moreover, the room does not have to be ventilated. They weigh only a quarter of the enormous weight of their lead equivalent.
6,No maintenance:
They do not require maintenance. The "Battery Management System" ensures that all cells are being charge and in balance proportionally. The battery only needs to be charged, and it is ready for use. This charging can be done one hour before use.
7,Loss of stress:
The discharge curve is almost flat. Which means that a battery with 20% capacity can give the same output as a fully charged battery. And prevents many of the problems that lead batteries have during discharge. Another significant fact is the enormous peak load that a LiFePo4 can deliver, even if it is already fully discharged.
8,Weight and size:
The weight is only a fraction of their lead equivalent, and the dimensions are also considerably more favourable.
