What Our Clients Say

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!

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 battery 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.

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

One of the best transactions of my commercial career (49 years long). The level of service from my Polinovel representative was exceptional. Despite the vast cultural differences her help and knowledge were exceptional. So far I have only undertaken a visual inspection of the goods but the workmanship appears to match the quality of the sale service.

I just wanted to let you know the batteries are very nice. I am very impressed with how they work. I can use them very hard all day, 12 hours-14 hours of fishing using my Lowrance Ghost 24volt trolling motor. When I get off the water I still have 85% battery life. The most I have used power-wise is 16%. On average its 10% battery use for a full day. These are amazing batteries, I can’t say enough great things about them, Thank you!
