FAQ - Frequently Asked Questions

What is the country of origin of your products? Where are they manufactured? I suppose, they are all from China, aren ́t they?

Yes, most of the products sold under the brand WINSTON, ELERIX and GBS are made in China. Let´s face the truth: actually, more than 80% of products sold in the EU are made in China. Production capacities, their technical background hand in hand with logistic infrastructure is high and more efficient then here in Europe, but more importantly: it´s already up and running. The manufacturers we are in cooperation have everything in order to produce high quality products: large premises with cutting edge technologies, experience and know-how in large scale manufacturing, just to mention the most important aspects. There is a number of different manufacturers and suppliers to choose from: we „just“ made that final selection of the best ones for us and for you

Why is the price higher than on the „internet“? Is it the yellow plastic that costs so much, or you are just trying to get a high profit?What do you specialize in?

If it were so easy business with so high profit, everyone would do it☺ In fact, even the application of the yellow or green packaging is not a simple task. Sure, it has its cost but in total, it is marginal. What objectively makes our prices higher are these reasons: first of all, the cells (and batteries that are made from) are an A-grade quality. Furthermore, it took us hundreds of hours in search for manufacturers, visiting them in person on sites, testing their products and fine-tunning them in regard to our requirements. Then there are costs related to the local warehouse (products are here, you do not have to wait weeks or months). Let´s continue with costs related to warranty extension, possibility to claim back either your money or a new product for a defective one as well as a possibility to consult the technical expert. And last but not least there are customs and tax fees. Saving you time, providing you comfort and peace of mind is something which is worth that extra money. The remaining part is profit.

Why is the price of the transport / delivery so high? Sometimes, it is as expensive as cells themselves.

Well, first of all, you have to realize that batteries and cells is a chemistry. Even though the fact that LiFePO4 technology is considered as a very safe one, it is dangerous. At least by the authorities point of view that set regulations for transport of goods. Therefore only specialized trucks and personnel can transport them, not a typical and omnipresent post delivery truck or pickup. It increases the price and yes, sometimes the transport fee might be as high as the cell or battery itself. Secondly, the packaging must be solid. We want to deliver your products intact and safely. A box made of cardboard is not suitable for every order, we have to use wooden boxes on palettes instead. That means additional cost, but we believe it is also in your interest. But hey: you can use these boxes for your plants, bottles of wine or just for storing some stuff in your garage.

Modular battery banks are fully configurable and repairable.
Thunder Sky Winston, GBS, and Elerix are ALL Modular

Whats in the Box ?

Good question - We know and will tell you whats in the box BUT Do you know know 'exactly' whats in your box ? If it is a sealed unit, it could be anything-
Did you ask ? If you dont know then you really should know -
Do you care ? Well, you should do as you are going to use it

If you are buying food in the supermarket you know where it comes from - same applies

If it is a MODULAR system - then we know - If it is a NON Modular system then we may know - please ask us
