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.

These things are SO comfortable! I feel like I’m walking on clouds 🩷 I ordered this tan and a black pair and I’m glad I did! I wish more colors were available in my size but apparently I got the memo late 😒. I usually wear a size 8 1/2 women and I ordered a 9 based on reviews with photos. The 9 fits wonderfully, my fat feet have room to spread when I’m walking and they provide adequate arch support. The color is as pictured, the shoe itself is cute, and I am able to walk normally without any discomfort…. If you are thinking about it, go ahead and get them girl they feel like heaven. Just order a half size bigger.

Love these shoes!
UGG dupes! These are amazing! I love how comfortable these are. I have worn these quite a few times now with no issue. Definitely worth the price! I have seen a couple of complaints about the durability of these, but at the selling price I would gladly repurchase these over paying for the UGG brand. They fit TTS. I will definitely be ordering these in the lighter color!

Sooo cute and comfortable!
I have two pairs of these sandals in pink and a cream color and they are sooo freaking comfortable! I have sciatic nerve pain so my leg gets fatigued fairly quickly from standing but I find these shoes allow me to stand longer and more comfortably. I’m hoping they’ll have the black sandals in an 11 back in stock soon because I want those as well 😆 If you’re looking for cute and functional footwear for the summer you can’t go wrong with these.

Not it.
Size: 10, Color: Nude, Size: 10, Color: Nude
I ordered these and was highly disappointed. The first pair I got, the velcro pieces were coming off. The threading was either coming undone or just wasnt there. On both shoes. I sent them back, had them send me a new pair, hoping it was just a fluke, cause those do happen. The next pair was better, but the corners on the velcro pads were still coming up, and i just didnt trust it to stay together. I sent them back and got a refund. As for fit, the first pair fit great, my foot was a little to skinny I think, or the straps were too loose even pulled as tight as they could go while still being able to connect the velcro pieces. It was something I could have probably worked with, they looked cute still and I still wanted to love them. The second pair, however, straps were still too loose. That didnt change. However, I got the same size, but this pair, my toes were too long for. Like, they were up on the little toe ledge thats supposed to frame your foot. That was uncomfortable. So I feel like the sizing was inconsistent. Another reason I opted to send them back for a refund. The shoes are cute, and i usually dont have issues with this brand. I have a couple pairs of boots from them that I absolutely love. But these sandals were a huge disappointment, unfortunately.

Comfy but run large!
Runs large IMO. I originally ordered a 7 and they were much too big and the straps were way too long. I ended up returning them and ordering a 6.5, and I love them. They are SO comfy and they go with just about everything. I will say the top strap gets smudged easily, but I’ve just been wiping them with a wet cloth and the smudges are gone.
