Battery guide

01





Are you fed up by having to recharge or change the batteries so often?
Try a type that lasts 10 times longer.



You've experienced this while using your mobile phone:

With each charge, the battery fills with energy, but as the energy is drawn, the battery essentially becomes clogged (solidified electrolyte settles on the electrodes).
You charge the battery with energy and then use it. But with each charge, the battery capacity drops slightly... and you get less energy. And after a few hundred charge cycles, the battery is completely worn out.

We all know this and accept it as a sad fact of life ... but you don't have to tolerate it any longer. (And feel guilty about the tons of old batteries ending up in landfills every day). At GWL, we have prepared a clever guide on how to choose a battery for your operation, cars, production lines, boats, buses, caravans, forklifts, etc. that will last ten times what the obsolete ones (which you probably still use).

It explains in detail how you can (with the help of just a smart electrician), replace the old type of battery with one that does not age so quickly (and will retain almost its full capacity, even after 10 years). It calculates your return on investment (and openly says when it is or isn't worth it).

And you can download the whole guide here for free.

Hundreds of thousands of companies and consumers have switched to these 10x longer lasting batteries over the past 15 years (and traditional manufacturers are trying to keep it quiet as they eat their profits away).

And after reading the guide (only 24 pages), neither will you tolerate excessive cost and unnecessary waste: In just a few days, you will be able to store, back up and draw energy for your company or home as reliably as you do today.

... but with a much lower cost and a better feeling that you are also protecting environment.

Is it worth it?

LiFePO4 batteries are a subtype of lithium ion batteries.
They are mainly used in electricity storage (households and power engineering), for industrial automation and selected types of electric vehicle. What are they made of and why do we choose them from the multitude of lithium batteries?

The selected LiFePO4 prism cells need to be properly prepped before assembly into a battery pack. This always involves first checking the voltage, polarity and overall condition of all cells. Only then should you initiate the recharging, arrangement, fixing in place and interconnection of individual cells.

We secure most battery packs with a management and control system (BMS-Battery Management System). This means battery protection against excessive discharge or overcharging. You can imagine this system like the emergency brake that you find in every single train carriage that prevents the entire train from accident. In practice, it is a simple electrical circuit which constantly measures the electrical voltage of each cell connected to the battery and alternatively the currents supplied to the battery and drawn from it. If voltage of a single cell within the battery exceeds the specified value, the BMS will disconnect the entire battery from the charger or load in order to avoid it being damaged.

Like the emergency brake on a train, disconnection components of the BMS cannot be the only precaution against a crash. A battery pack needs to have a routine method of charging and discharging, like a train’s regular service brake. Disconnecting the pack by BMS is an emergency event, not a piece of ‘information’ for a superior system. Sudden and unexpected disconnection of connected modules from the battery via BMS can cause irreparable damage. Likewise, a sudden outage can be considerably inconvenient for users (equipment ‘suddenly’ stops working, the lights go out…).
