TESTMONIALS

The 150Ah battery is fantastic! Really self supporting during the whole holiday. I want to change the battery of the electric bike of my woman. Also in LiFePO4 if possible. Soon I will see want is insite of the battery an what space there is for the new one. Maybe you can advise me when I am so far.

Henk Goeman, from Holland

I received the batteries today and could not be happier!  I will definitely do business with you guys in the future after this initial production run. I appreciate how easy it is to work with you and how great, safe and dependable your products have been during my testing. Take care over there! You guys are the best.

Casey, from America

We are using your batteries, and all seems OK, thank you. Our possible customer asked about a “double capacity” pack. We would nee to double the current (2 x 11,6 A), keeping the same nominal voltage (29,6 V). I assume that we need a 8s8p configuration.
