12v and 100A Ultimatron lithium solar battery measuring 355 x 175 x 188 mm Ultimatron ideal for solar installations in caravans and motorhomes
Lithium batteries are the most modern battery models, they can work for both isolated solar installations and self-consumption solar installations. This battery works at 12V but can be installed either in parallel to increase the capacity or in parallel to increase the voltage to 24V or 48V.
This battery has a charging capacity of 100 amps or 1,280W
Integrated Battery Management System (BMS)
Integrated Bluetooth 4.0 monitoring
Allow the control and charging of the different elements of an accumulator battery and protect it from overloads, overvoltages and overheating
Lithium iron phosphate (LiFePO4) has been widely adopted by the lithium battery industry. It is very stable, without risk of fire or explosion, even with an elemental BMS.
The lithium battery is also characterized by the large number of charge-discharge cycles it supports, around 3,000 discharges compared to a few hundred for most batteries sold (lithium or lead). It also has a particular characteristic, a kind of inverse memory effect: the lower the discharge, the higher the number of cycles, which makes it particularly insensitive to microcycling.
Finally, it tolerates extreme ambient temperatures quite well, from 0 ° to 60 ° C. With a quality BMS, it is a very reliable battery, capable of providing service for many years.
Lithium batteries (Lithium Iron Phosphate) offer many advantages over lead batteries.
They have a much faster charging capacity, allowing even the smallest amount of sunlight to be used without being limited by the internal resistance of the battery.
A lead battery, depending on its capacity, will be limited in its charging capacity. With lithium, it will be charged to the maximum of what the controller can give.
Also unbeatable in downloading, they easily support very fast downloads.
Comparing the price per available amp hour (with lithium you have a very high depth of discharge) we can see that the price per available Ah is a little more expensive than lead batteries.
