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.

It works well!
Style: Skin Saviors 4 Piece Set, Style: Skin Saviors 4 Piece Set
My fiancé was breaking out. His whole life he has just been cleaning his face with regular bar soap. I bought this for him after reading the ratings and I’m impressed. His face looks a lot clearer and it’s only been a week. He said he likes that it doesn’t make his face feel dry like the bar soap did and his blackheads and pores have also gotten so much better. There’s quite a difference! For the price of this, I’m impressed. This comes with the 4 products as shown and a sample of the beard oil they make as well.

Complete intro to skincare
Style: Skin Saviors 4 Piece Set
Cleanser: Gentle for daily use, but still leaves me feeling fresh and clean. No noticeable scent, easy to lather and rinse. This is my current favorite cleanser. Scrub: Too harsh for me. I feel like I’m raking it across my skin. Even compared to the Turbo salt scrub they make, this facial scrub feels harsh. I use it sparingly: maybe once a week. No noticeable scent, easy to use. I’d much rather exfoliate with the Glycolic ash mask or multi-acid peel pads they make. This product is not something I’d buy again; it’s good, but they make better exfoliators. SPF moisturizer: Feels very clean and light, and combines the moisturizer and SPF into one quick step, which is always nice. No noticeable scent and absorbs fast. I usually go with a different moisturizer with higher SPF though. Lip balm: Nice and simple formulation, moisturizes well and stays protecting for a good long time. The SPF is a must, and I have several tubes of Jack Black lip balm for this reason. The mint one that comes with this set is too strong for me, but at least the mintyness dissipates relatively quickly. All together, this is a complete skincare routine made up of good products. Cleanse, exfoliate, moisturize+SPF in one step, and an SPF lip balm with a minty scent to top it all off. I’d get a different exfoliating product (Jack Black glycolic mask is my favorite). If you want a complete intro to skincare with quality products in one complete set, this is a good place to start.

Love it
Style: Skin Saviors 4 Piece Set
I got this for my fiancé who didn’t do any skincare prior to me purchasing this. I got this for him and it’s been really good, he has been using it consistently. In his words “it’s a great stepping stone for people who wanna get into skincare”. It’s got all the very basic essentials of skincare so it’s simple, quick and easy to stick to. Definitely would recommend!
