Lithium-ion batteries are the best option available. Maintenance free these batteries can produce around 5000 – 7000 cycles making them a great long term option.
With Lithium, you won’t even know it is there, with little to no maintenance is makes it the easiest autonomous option that is also one of the most environmentally friendly batteries available.
Lighter and Smaller
Lithium-ion batteries are lighter and smaller than Lead-Acid batteries, roughly a third of the weight and half the size they are better for those who are limited in space.
Slim and Sleek Design
They are much better looking than the Lead-Acid batteries which are bulkier and look like car batteries. High-end Lithium-ion batteries like the variations that Tesla produces look futuristic.
Lithium-ion has a Depth Of Charge of 80% unlike Lead-Acid which has 50%, they can discharge completely without losing amps.
Lithium batteries can average around 6000 cycles making it a great long term solar storage option, take a look out the PylonTech battery that offers this.
Consistent Discharge Voltage
On discharge, the voltage is inconsistent with Lead-Acid batteries, Lithium-ion batteries stay consistent throughout the discharging process making it a better and safer option, protecting the electrical components.
Better Long Term Option
Although the initial cost is higher the return on investment is better. The lifespan and ability outperform the Lead-Acid option.
