4 reviews for NEX72S 72V 33.6Ah Battery for Sur-Ron / Segway Electric Motorbike

  1. Brian

    Best battery on the market. Only 72v thst fits and looks stock. Side charge ports, clear display and awesome range. Don’t buy anything else

  2. Benjamin Gates

    Absolute best battery available keeping the bike stock size and weight. I didn’t want a 50lb mass sitting in my bike and this was the perfect solution. No bypassing, can safely charge it in my house and capable of over 21kw dc! Dual charge port was also really cool being able to charge from either side or use both for quick charging.

  3. James Bowen (verified owner)

    I have had this Battery for a few months now and it has performed perfectly. It even fits inside the 4M Foundry Kit. Highly recommended!

  4. michael (verified owner)

    Very compact and powerful. Been using as a daily commuter, much more range than I expected. Cells barely heat up even when dumping amps.
