The passionate sailor Peter Reinmann extended his lead acid energy storage of his 9.30 meter long sailing catamaran with two BOS LiFePO4 Lithium modules. Peter is thus able to operate all the on-board electronics such as navigation, radio, light, refrigerator and gas heating. Because there was no room under the bench seat for a larger supply battery, a LE300 hybrid system was the perfect solution without loosing too much space. Now he is able to enjoy longer trips on the water without returning for recharge. A freedom that he no longer wants to miss.
Lithium Extension Battery
BOS LE300 Smart Battery System is a fully scalable solution to enhance performance and upgrade capacity of lead-acid batteries in solar or any applications with storage needs. They can be used with new or existing 12 V lead-acid battery systems. Easy to install, by simply connecting the LE300 in parallel to lead-acid batteries. Its capacity is very flexible and can be increased by just stacking multiple LE300 in parallel until you meet your system’s needs!

Works with any lead-acid battery and any application
LE300 Smart Battery System can be used wherever a 12 V classic lead-acid battery needs to be extended. The scope and application of the LE300 is such that customers often inspire us with new ideas and possible application areas. Right from solar home systems in Africa to mobile homes and boats in Europe, LE300 has touched every kind of storage application you can ever think of!
Lithium for cycling.
Lead-acid for basic load.
In pure lead-acid systems, batteries often fail within one to three years, as batteries get damaged by continuous operation at low state of charge. Pure lithium systems perform way better and show longer lifetimes but are expensive and complicated to install. LE300 Smart Battery System turns your lead-acid system into a lithium system with special features. And the best thing about it: It only takes a few minutes to install before it can make a real impact in your storage system.
Charging & Discharging Cycle
With the LE300 hook up, the lead-acid battery is kept fully charged, while the cycle-resistant lithium battery takes on most charging cycles and is preferentially discharged under load. The capacity and the performance of both batteries are used optimally, so you can look forward to a better performance and a longer life span of your batteries.
Longer Battery Lifetime. At Low Costs
The lithium battery takes most of the charging cycles while the lead-acid battery provides inexpensive backup capacity. The lead-acid battery is charged with higher priority, while the lithium battery takes all surplus energy. This process helps to increase the lead-acid battery lifetime to up to ten years.
Robust housing for automobile. Protected against bad terrains
An elegant design and robust housing keeps the lithium batteries safe, even when you are driving off-road or bad roads. Thanks to an optimised sizing and variable fixing possibilities, the modules fits even in smallest of the corners. Each module is E1 certified which allows them to be installed in automobiles as well.
Easy to scale up. All your needs are covered
LE300 modules can be easily stacked together to meet your individual energy storage needs. Up to 24 (7.8kWh lithium capacity) of them, on top of your present or new lead acid battery. As mentioned, all your needs are covered!
Retrofit or extend your lead acid battery. Hybrid technology
LE300 Smart Battery System can be connected to any new or existing 12V lead-acid battery. Thanks to the intelligent design, no additional charge controller or electrical wiring changes are needed.
Low temperature resitance. Works with any climate
All LE300 modules have an integrated cell-heater, so the lithium batteries are protected against cold temperatures and perform without any energy losses. At low outside temperatures, the heating can increase the cell temperature by 5 to 10 degrees celcius.
Plug & Play. Ease of installation
With the plug and play design, LE300s are easy to install and operate. They simply need to be connected with plus (+) and minus (-) terminals of the lead-acid battery. Installing lithium batteries was never this easy.
