Our Client's Endorsements

This was my first order with a Chinese business and I was most impressed. They were clear and willing to answer any questions or vary the product if necessary and took care to make sure they were supplying a suitable product. I am going to explore the possibility of importing more batteries for re-sale in the UK so hope this is just the start of a happy business relationship. Thank you.

I purchased three of these to use as the house batteries bank on my boat. Typically they would need to be carefully charged to up a matching voltage before connecting them in parallel. I was very surprised to find that the voltage of all three matched exactly right out of the box. I suspect that Polinovel selected matching cells in the assembly process to make these match so well.

Great product and excellent value. The company produced them in a fast time and used very fast global shipping. The batteries look like they are high quality and the LCD display works great!

The person in charge is kind and the product is of very good quality. The batteries purchased three years ago has the same performance as a new batteries. Great!
