BOS Lithium Extension Battery LE300, hybrid battery for marine systems, high efficiency and longevity - Optionally with 2-block, single module, 4-block

The LE300 is the first lithium battery that turns the existing lead-acid system into a hybrid battery system. It is only connected in parallel to the existing lead-acid battery bank. This makes the most of the advantages of both systems in the marine sector. The lithium technology has clear advantages in the charge cycle stability and high efficiency, a lead-acid battery has advantages at low temperatures and short-term very high power requirements.

With the use of the LE300, you can thus extend the life of the overall system up to 10 years and more. You have flexible mounting options and can implement the latest technology without having to rebuild the entire charging system. You can retrofit additional LE300 modules at any time. The LE300 also monitors the lead-acid battery bank and automatically recharges it when needed: ideal for extended periods in port without shore power.
