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.

No challenge for a M/L dog
Color: Pink
Too easy for my 30 pound shepherd. The puzzle moves around easily. It’s fun for him but he goes through it quick, not enough working through it time.

My cats are too lazy for this
Color: Pink
I bought this in hopes that my cats would find it entertaining, as they've never had to work for treats before, they unanimously decided to simply meow and look cute. THATS all it takes and poof! They get a treat.. (It gets me every time). It is an interesting well made item and seems sturdy and intriguing, my cats are just spoiled Lil stinkers who don't want to "struggle" to get a treat...lol

Perfect puppy starter kit and gift! Perfect for plane rides and kennel!
Color: Neutral, Color: Neutral
Perfect puppy gift! We use the kennel as her safe haven, and for potty training . This heartbeat tool is amazing and helped our puppy get acclimated to her kennel. She goes into her kennel and sleeps with it on her own. It calmed her down on the plane completely. We had a 6-hour flight and she did fine with the heartbeat toy. At home innthe kennel, the whining was very very minimal the first couple days, then it stopped. As you would hear and see her snuggle up and fall asleep. I think it is a bit pricy, but not too bad for the benefit. The heartbeat is seperate and is putninside a pouch on the stuffed animal. The blanket is soft, beautiful and perfect size. Good quality fabric. Both chew toys were loved by her.I do notice my large breed puppy prefers the rope and small tennis ball type chew toys. However, she plays with these too. Haven't used the heating packs yet, they go inside the pouch with the heartbeat item. I am sure we will because my puppy does love to be in front of my small heater under my desk to keep my feet warm. The packaging was extremely nice and fancy and was complimentary to the items inside.

Best Idea for Puppy's First Day Home
Color: Pink
I was a bit reserved on purchasing this kit because it was a bit expensive. After a month now with my pup at home, this was the best investment for us and our GSD. On the first night, we used the heart beating snuggle puppy and blanket. She slept the entire night without an accident or a cry. The heartbeat in the snuggle puppy and the heat pad was the best idea. Our puppy never felt alone (just fyi, her crate was in the room with us for the 2 weeks). A month later, she is so protective of her snuggle puppy. We only used 1 heat pack to soothe her during the first week. The heat packs last a while. Our GSD now uses the snuggle puppy as a pillow or an object to be close to while she is in her crate. Any new puppy owner could definitely benefit from using this. Of course, with all things puppy, it does require a bit of time to correlate toys as a positive thing. We exclusively keep the snuggle puppy in her crate and make it a part of her secure place. My GSD puppy did really care for the teething heart toy. Even after freezing it, she didn't care for it. She also outgrew the small toy. She will chew it from time to time but it doesn't entertain her much. I found the kit, overall, very helpful with our puppy's adjustment to our home. She sleeps through the night since 8 weeks old and now at 12 weeks old. We've never had an accident in her crate overnight with the help with the snuggle puppy.
