  • Pylontech Battery Diagnostic cable

    Great kit. Nothing in this kit is "the cheapest part" that they could find. The USB cable is quality, the network cables are long, the USB drive is well built and the magic box is very nicely put together. I know I could have built a cheap kit for around £20, but the software and the quality of this one is well worth the asking price. Worked first time on old windows laptop. Excellent equipment all over. - Buyer:muppet.keeper (254)
