SL-2440-4

● Light, powerful, and offering a very long viewing time, this Lithium-ion battery is particularly suitable for cyclic use, when batteries are frequently charged and discharged.

● Built-in BMS. 100% of the capacity is available for your needs, without voltage drop!

● Lithium batteries (Lithium Iron Phosphate) offer many advantages over lead batteries.

● They have a much faster-charging capacity, which allows you to use even the smallest amount of sunlight without being limited by the internal resistance of the battery.

● With lithium, you will charge with the maximum of what the controller can give.

● Unbeatable also when discharging, they easily withstand very fast discharges.

● Comparing the price per ampere-hour available (with lithium you have a very high depth of discharge) we can see that the price per Ah available is just a little bit more expensive than lead batteries.

● Service life at 80% depth of discharge (DoD) ≥ 3000

● Service life at 50% depth of discharge (DoD) LiFePO4 battery ≥4500
