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.

Excellent Rivals to Lovers!!
Format: Kindle
The tension and banter between Huntyr and Wold was delectable. I absolutely love the fallen angel and all of his flaws. Huntyr is amazing too being a badass FMC with some major trauma. The world building was great and I enjoyed the training aspect of the story. The writing was immersive and was in the story the whole time. The ending had quite a twist that I hadn’t anticipated and made my jaw DROP. Excellent job! I also loved the narration. Laura is one of my fave narrators!

Fallen Angels, fae, vampires, oh my!
Format: Kindle
Rating: 4.5 | Spice: 2 (but a good slow-burn) • Main Characters: Huntyr and Wolf • I couldn’t wait to read this book; there was so much hype about it! And there was no doubt why. I fell in love with the characters and the plot itself. This book is mainly plot driven more than friction driven but it’s easy to follow along with. The characters are fun, easily understood. The main setting is at an academy where both the main characters are going through trials and building strength for the final test, The Transcendent. There are fantastic side characters as well. I loved the camaraderie between Huntyr and her friends. But we don’t like Lanson. 😆 We do have some plot twists that come into play throughout the book. Secrets and betrayal to be seen. I did adore Wolf and Huntyr’s relationship. It was a classic slow burn trope. They didn’t hit it off fast, but in time their feelings grew. I loved their banter, so sexy. Wolf is your next book boyfriend; Huntyr is your next vampire assassin independent bad-a*s female. Themes include loyalty, trust, self-discovery, a true slow burn romance. Side note: book ends on a angsty cliffhanger! • Emily, thank you for writing this awesome novel and I cannot wait to devour Book 2, Blood So Brutal! 😍 • Happy reading, my lovelies! xo

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟 This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens. The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him. I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure. My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times. Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️ I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well. Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on. Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc? However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy. Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book. Overall ratings: Plot- 3.5⭐️ World building 3⭐️ Spice 2.5 🌶🌶 Main characters 4 ⭐️ Supporting characters 3.5⭐️

great book
Format: Kindle
I am really excited to meet the author at the book retreat this month. I really enjoyed this world that she built and most of the female main character Huntress is so awesome. She goes through a lot in this book and the ending; wow! I wouldn't have even guessed. I highly recommend everyone to read this book. I have been so lucky this year that almost all the books I have read have been, so far, 5 out 5 stars.
