The LE300 smart battery system is a lithium extension for 12V lead-acid batteries (AGM, GEL or wet cell).The integrated battery management system takes care of protecting and balancing the lithium cells while monitoring the lead-acid battery. The intelligent distribution of loads and capacity in the LE300 continuously keeps the lead-acid battery at a full charge and therefore extends the battery life.Plug & Play installation: simply connect the system to the plus and minus pole of the existing battery with no need to modify the circuit or the charging technology. The LE300 modules are light, compact and modular, and can be combined up to 24 in parallel, increasing the battery capacity to experience self-sufficiency.
