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.

I originally got the King set & loved it so much I ordered another in Queen size!
Color: Charcoal, Size: King
I didn't add a picture because the advertised picture is exactly what it looks like (and my beds not made at the moment, lol). It's so soft, comfortable, cosey and warm. It's thicker and fluffier than I expected, but still very lightweight. The price was great for a king size bed with 2 king sized pillow cases! I love it so much I ordered a second set in Queen size, just to have the cases for my smaller queen pillows that go in front of the King pillows and to have the extra blanket as a cozy throw. The only drawback is it does snag easily on rings, fingernails, etc. (also another reason I ordered the second one to lay across the places that I've snagged & a few that were already snagged when I got them). However, it's so cozy that I didn't want to go through the hassle of sending it back and having to wait for a new one! I'm very glad that it was suggested as an add on when I ordered the mattress pad & that I chose to add it on. I'd definitely recommend it to anyone!

Warm, cozy, soft, 💜 love
I don't leave reviews very often (yes that is cliche) I just don't have time. I have been debating for a few months one what I actually wanted to do with my bedroom. Spring is coming and the dark is getting to me and wanted to still get an elegant feel. I have some light baby blue around in my other comforter but I needed lighter brighter. I saw this and how SOFT is looked and I LOVE soft and cozy, who doesn't? I am so glad I took the chance. With that I also ordered the pillow....what I thought were pillows but didn't read very clearly they were just the covers so I ordered pillows then the picture I knew would still be elegant but be able to tie all the peices in and OFF the internet. Sometimes colors are not the same online as in person since monitors are always different shades of a color. Now on to this comforter. I didn't realize it came with the pillow covers. 💜 the set comes vacuum sealed but it is heavy when vacuumed. I undid the packaging a day later when I had time to wash. The cover flew out and I was perplexed, it's a pillow cover!!!! Awesome!!!! Ohhh there's 2, woohoo! Omg it's so soft. Oh I'm in heaven. Mmmmm hugging the pillow cover, I knew this was my kinda softness bed comforter. It is not LIGHT weight like say a throw blanket but it is light vs heavy bulky goose downs even though they say those are light. And when you wash it, its def not heavy if u spin the water out at super high setting on ur washer. I was able to carry it to the dryer fairly easy 20 ft away. This is by far the BEST comforter I bought in my life. I am a hoarder when it comes to comforters. Thinking if I'm ever homeless I'll have lots of somethings to keep me warm. For the price and the quality, (the batting inside doesn't shift when washing) this will be another purchase in the future in another color so I can start a soft collection. I usually give my comforters that I dont use ( the oldest but still perfect condition) to a friend or homeless. Great product!!!!
