What is the behavior of a LiFePO4 battery at low winter...

Comes winter, most of you are interested in what is the battery capacity in lower temperatures, what is a discharge and how to charge your battery. We will try to sum it up for you and will start with battery capacity.

If the temperature in the place where your battery is stored reach

LITHIUM BATTERIES: WHICH TYPE IS SAFER? - LiFePO4 vs LTO vs...

Li-Pol (LiPo) are widely used in nearly all cell phones and other home electronics. Yet, they are unstable and dangerous.

In our test, we compare LiPo with available LFP and LTO technologies. You may not recognize the danger sitting in your pocket, but consider the danger for projects involvin

FAQ: Transporting empty lithium cells

Question:I need to transport the batteries by air. Is it possible that I discharge the battery (LTO, LFP, etc) to zero volts, transport and recharge back after reaching the destination? This way the battery will have no energy stored and will not be dangerous. What do you think?

We are sorry t

The CPM improvements in progress

We are working on improvements for the. The modifications of the firmware will allow improved settings and communication with theCell Communication Module.

We have also madethe RF (radio frequency) emissions teststo make sure the GWL Modular CPM board is withing the EMC requir

What is the “Charge Booster”?

The“Charge Booster”is acharging converterbetween the regular car starting battery (usually lead-acid – SLA) and the auxiliary board battery (often the LiFePO4 – LFP).

It also works as a separation between these two batteries. If the starting battery gets

A photo shows a complete mobile installation for a Mobile-home (Caravan). This installation is based on the 12V battery pack using the LiFeYPO4 cells from Winston Thunder-Sky.

We will be showing more details about this installation and the components used.Stay in touch!

How to build and choose a battery for a sailing yacht

A lot of the questions about batteries are related to changing the old battery for the new one, or building a new project as building the electrical system on board.

The optimal solution for this case is to use LiFePO4 cells which aresuitable for electric boats, cars, and other EV applications. It is due

Battery charging from a generator on boats

FAQ: Battery charging from a generator (alternator) – on boats

Question:I have a boat with the gasoline engine. The gasoline engine moves the boat and charges the mainboard battery. When I replace the battery with LiFePO4, how should I operate the charging? If the battery gets full the alte

Winston cells and mechanical shocks (for automotive or for...

Question:Can the Winston battery sustain the mechanical shocks and constant movement that exists in boats on the open sea?

Yes. We have customers who deploy the Winston battery cells in various applications that have constant shocks. We have customers from the marine industry – see brief r

FAQ: Is there any limit on the maximal capacity of the Winston cells?

No. There is no limit. The maximal size of the commercially available cells is. (The 7000Ah andare not available for public sales). You can putto increase the capacity of the battery bank. In this way, there is no theoretical limit.

FAQ: Is there any limit on the maximal capacity of a battery for a sail-boat? (For example, some kind of safety regulation limit, etc.)

No. As far as we know, there is not a
