Antigravity Batteries© AT7B-BS RS Lithium Ion Battery w/BMS and Re-Start Technology - Fits All Ducati© Panigale Models - Replaces YT7B-BS, YT9B-BS

I have neglected this battery on three occasions, completely dead. I use the restart feature, before plugging it into my optimate. It has come back to life every single time. Amazing battery, it may cost a bit more, but I am used to buying a new acid battery every year after winter. And because its Lithium it charges fast and is very light on my bike. Fits in my DRZ400SM like a glove, easy to connect. If you're like me and fail to use trickles sometimes, this may save you some money in the long run. Cheers

Liked the feature of restart system, also liked the weight savings over the OEM battery ( -3.5lb ) Nice.

I installed this in my Ducati 2020 Streetfighter V4 when the OEM battery died. I was skeptical at first - the battery weighs nothing and I was thinking "how the hell is this going to turn over that big high compression V4?". My concerns were unwarranted - the bike started right up and has been working flawlessly for several months now with no top up charging required between rides - winter time here in NC so not many opportunities to ride at the moment. It's expensive for sure but it's amazingly lightweight, a perfect fit and does it's job well.

The Good: It's a great idea (also, fitment was 100% perfect) The Bad: This battery just doesn't work. The battery arrived dead. Given that the company claims "low self-discharge" seem this should not be the case. Not checking the voltage, I just installed it into my Yamaha TTR250 (which fit perfectly). I did have the issue noted by other reviews that the connection bolt is a larger diameter and I had to drill-out the ring connector. After the battery was installed I hit the starter button on the bike. Nothing. So I pressed the 'restart' button. Still nothing. It was a this point I figured I would need a volt meter, and my charger. When I looked at the voltage across the terminals it was way under voltage (see image). So, I hooked it up to my NOCO Genius 10 battery charger (by the way, NOCO makes super awesome chargers!). I messed around with the charger and battery (pressing the re-start button) for some time trying to get the charger to "see" the battery and then finally was able to set the charger to "Lithium Mode". So I let the battery charge. After disconnecting the charger, and re-installing the battery, I still could not start the bike. Battery seemed dead. I was able to get the headlight to turn on and off momentarily, but there was not enough juice to crank the engine. I checked the voltage on the battery only to find it around 8.7v! I've simplified this review a ton. I did end up spending a couple hours trying various combinations of installing, un-installing, pressing the 'restart button' and attempting to charge the battery. All to no avail. I would not recommend this battery. You are going to have 100% more reliability from a standard AGM sport battery. Update: Still no response from Antigravity. I ended up going with: Yuasa YT7B-BS AGM Battery
