Would you like to expand the lifetime of your LTO cells?

Are you looking for a way on how to connect the cells
to ELERIX Cell Performance Monitor (CPM)?

Check our new video guide from GWL production where Petr (our Technical Specialist) describes the step-by-step process of how to connect YinLong LTO cells to ELERIX CPM.

Take care of your cells and keep them away from excessive discharge or overcharge.

GWL cooperates with EVLithium who distributes the goods to Asia, Oceania, South America, or Africa where the distribution from Europe takes too long or could be expensive.

EVLithium delivers the batteries by ship and specializes in intercontinental shipping outside of Europe.

South America takes around 3-4 weeks by ocean.

Africa takes around 3 weeks by ocean.

Australia and New Zealand take around 2-3 weeks by ocean.

Another YouTube Video is out from GWL production!

This time we took a closer look at well-known and reliable
12V ThunderSky Winston

You are going to find out:

• How to properly use the battery
• What types are on the market
• And for what types of applications is the best

Also, we have opened up the battery to see how it looks inside.

One cell is almost never enough for proper energy storage and therefore a stack of cells is needed to reach the desired capacity.

For such a case, we recommend using ELERIX Pack holder which was precisely designed for 8pcs of ELERIX EX-110 LiFePO cells.

All in one packing and our step by step manual makes this kit easy to set up just within a few minutes

The ELERIX holder features:

• Simple and safe manipulation with the cells, easy integration for various applications
• Mechanical readiness for mounting of the BMS components and additional extension modules (DIN rails and punched side plates)
• Full mechanical protection of cells against external mishandling
• Simple access to the individual cells and quick replacement of any cell and other components

Store the energy into reliable ELERIX cells. You power the life!

The YinLong battery cells are here even with more power now
- 45Ah types.

• Can be charged in 6 minutes
• Life-span about 30 000 cycles
• Very safe LTO technology - no ignition, no explosion
• Wide temperature range -50°C to 65°C

A few years ago we made a popular video about
YinLong battery cells.The video describes the usage and advantages of these cells.

You can watch the video here → YouTube video about LTO YinLong Cells

They are here! The new, high-quality LFP cells are available for purchase now.

ELERIX 110Ah & 50Ah cell excels especially in:

• Well tested high quality = high production for long lifespan
• The practical size and weight
• Diverse suitability: electric vehicles, lightweight application, energy storage

Why do we recommend ELERIX Cells?

GWL always tries to offer the best, our company-tested products for reasonable prices. One of the successful outcomes that came out through our precise testing and deep analysis is the new brand - ELERIX. The cells labeled by this brand can assure you the highest quality for a good price.

Have you ever looked at your roof and told yourself: "Great! Now I'm energy self-sufficient...but I wish it looked better on my roof" ?

Our elegant full black version of a solar panel could help you out in this case and get you rid of this thought.

With a combination of the black color of cells (mono), black frame and black cover of busbars, the solar panel makes an attractive full black design which looks great on a house roof and gives the panel a nice “neutral” look.

The full black design of panels is then the opposite
of the classic poly design, where the poly cells, on the other hand, create a blue-ish look.

Well, just look at the picture, where you can spot the differences :)

Vs

• Fast charging and discharging - max. charge/discharge rate 10C (this means 400 A)
• Wide working temperature range - -50°C ~ 65°C
• Long life time - over 30,000 cycles (with DoD 80%)

Introducing DC powered off-grid energy solutions: DC/AC Inverter Steca XPC 2200 with charger and backup function. The Steca XPC 2200 can be connected both to the battery pack and have the AC grid as the energy backup. The inverter has been tested to work with LiFePo4 battery pack of 24 V. This inverter has high power rating for peak supply and over load capability. This inverter is recommended for off-grid/hybrid installations with the typical supply up to 1600W.

We have increased the offer of various models of the small capacity cylindrical LiFePO4 cells. These cells are ideal for low energy equipment and for many energy applications where tradicional round cells are used. We now carry the 3AH, 5AH, 8AH, 10AH, 15AH and 20AH models.
