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 was shocked by how much my daughter's puppy enjoyed this toy!
I've bought two of these — one for my grand puppy to use when she's at my house, and another for her to keep at her house. I was shocked that she actually seems to enjoy playing with this toy! She hunts out all the bunnies and then brings the carrot to me to refill. I refill it, and then she takes the refilled carrot back to her spot and hunts them all out again. If I can't find one of the bunnies (because it's gotten stuck in the couch cushion, for example), I ask her "where's the bunny?" and she helps me find it! This dog is a ferocious chewer but she doesn't chew these toys! It's like she instinctively knows they are for hunting, not chewing. As a result, they have lasted a long time and provide hours of quality fun. Great value!

My Iggies LOVE this toy. Buy it!!!!!
As a new dog mom to Italian greyhounds, I wasn’t sure if they’d like this, but it is their favorite toy!!!! They LOVE playing with the rabbits, chewing on them, squishing them, flinging them and chasing them. My one iggy likes to chew on the carrot and stick her nose in it when it’s empty. I find the rabbits around the house. So cute and seems to be well made. Definitely worth the cost.

Very cute and well loved dog toy.
I have two maltese rescue dogs. One if still a puppy and the other is almost 5 years old. The youngest one is a chewer and goes through toys removing whatever she can as soon as she can. This is a VERY cute toy and comes with the 4 cute bunnies inside. My older dog loves to take the bunnies and cuddle them in her bed. So far the chewer has not been able to take them apart and for that I am very pleased. Very well made, stiched well. I was reluctant at first to purchase because of price, but I believe this is good value for your money.
