You will be delighted to hear after nearly a FULL year of using your batteries, there has not been a single problem. Doug Herbert was super impressed at Romaniacs last year. He left the bike to help someone up a really tough section. Electric Fan was running full on for ten mins, and after he needed to start 6 or 7 times to get up the section himself. Was super happy about your battery, he is renting a bike organized by me again for the special 10th Edition of Red Bull Romaniacs and specifically asked if I can get an EarthX battery for him and Sean Clarke. Both riding 2 stroke Husaberg Te300/250 cc models.
I was especially delighted when one bike I keep for ”Pro competitor rental only” that was in storage for 7 months, early autumn to late spring, started second press of the e button. Now that’s is super impressive for a dirt bike. Never seen that before !!
Your earthx battery has been also twice used by Paul Bolton of extreme hard enduro fame and has got him onto the podium twice.
