  • Dumbproof
Great battery. Thought I fried it with my ECM and signals doing some wiring. However the built in module saved the battery and the built in “restart” or jump feature brought it back to life to charge. Super light. Bike fires up instantly. Would be again.

  • Great fit
Great for and performance for my 2022 BMW R1250RS , less then half of the weight from a stock battery, I highly recommend, I’m happy I made the right decision

  • No shims or spacers
So far so good. Can't give a real accurate review till it's been a couple years. I like the features and power it has. Cranks my bike over right now. Just wish it came with some shims to customize the hight/width and spacers to bring the terminals to a flush mount like the stock Harley batteries. Other than that giving me a frustrating install cause of the placement design for a Pan America. For the price I should have a reliable product for years to come. They seem to have a good reputation. You get what you pay for and hope it's not a really expensive turd. ... show more

  • Great battery.
Great battery for the money. Fast shipping. Charged battery as directed in the instructions, installed in my machine and it worked like a charm. In fact, it worked much better than the factory OEM battery.

  • Dies 6 months in with charger attached and unused.
I installed this battery on my 2011 Sportster and was initially impressed with the performance. It would quickly start the bike with ease and seemed to be working fine. Then I left it on the lithium specific charger over winter and now it doesn’t even have a charge. The charger doesn’t recognize it as a battery at all and it has completely failed. I purchased this battery less than a year ago. Never again. ... show more

  • This battery is the business!
Starts my Triumph Bonneville with authority, and saves quite a bit of weight doing so. I haven't used the Restart feature yet, and I hope I never have to. The peace of mind knowing that I have it though, justifies the additional cost.
