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.

Please note that the LE300 is not waterproof and will need a waterproof casing (battery box) if installed in a wet/damp environment.

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 resistance. 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 Celsius.

doesn't open can, leaves aluminum shavings
could not cut through rim of can at all, it barely even grabbed on even after trying on multiple cans. Just spun almost in place and left small aluminum shavings and slivers from the can on the counter. the mechanism does not compress and bit into the can enough to get through, just enough to tear it up

Excellent Can Opener – Safe, Effortless, and Smartly Designed!
I’m so impressed with this electric can opener! From the moment I took it out of the box, it was incredibly easy to use—just one touch and it does all the work for you. What really sets it apart is how it opens cans with a smooth edge, so there's absolutely no worry about scratching yourself or dealing with sharp, jagged lids. That’s a huge relief, especially for someone like me who cooks often and has had accidents with traditional openers in the past. The design is compact and sleek, making it easy to store in a drawer, and it feels solid and well-made in the hand. It’s also surprisingly quiet while running. I’ve used it on all types of cans, and it works like a charm every time. Honestly, I didn’t expect to love a can opener this much, but it makes such a difference in the kitchen. If you're thinking about getting one, this is 100% worth it!

Effortless Can Opening – A Game Changer in the Kitchen!
I absolutely love this Automatic Electric Can Opener! It makes opening cans so much easier and completely hands-free. No more struggling with manual openers or sharp edges—this gadget does all the work for you with just the push of a button. The smooth edge cutting is a huge plus because it keeps my family safe from accidental cuts. It’s lightweight, easy to use, and works perfectly with just a couple of batteries. I especially appreciate it when I’m multitasking in the kitchen because it saves so much time and effort. Honestly, it’s a must-have tool for anyone who cooks regularly, and it would be a great gift for seniors or anyone with hand pain or arthritis. Highly recommend—it has truly made my kitchen life easier!
