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.
Mr. Ullmann

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!
Mr. Cobb
