Anyone here running a lithium batter in place of the OEM Yuasa on their Hyper’s? Specifically a 2016 & up 939SP? Looking to upgrade & not sure if I want to go EarthX, AntiGravity, or even WPS. Any firsthand experience? I had a Shorai on my Speed Triple 1050 but I only used it a few months before I sold the bike.

I have EarthX on three bikes and have had no issues! Light, high output, faster cranking

I have an AntiGravity in my Panigale 959. Very strong with near triple the CA of the OEM Yuasa.
Only criticism is their claim that it's a direct replacement to the OEM. This is not true.
Although the new battery has the same dimensions as the OEM, the Anti Gravity's terminals are positioned further inwards where the cables do not reach.

I live about 15 minutes from Anti Gravity’s HQ...I think I will pay them a visit. Send me a couple pics of your Pannigale & I will bring it up to them. Which model Anti Gravity do you have?

The Model is YT7B-BS LIGHTWEIGHT LITHIUM-ION ANTIGRAVITY BATTERY 320CA (Ducati Panigale 959 OEM replacement)
I was finally able to get the cables to reach the terminals but only after removing the rubber insulation boot from the Panigale's battery cradle and using a lot of profanity. The main bike cables are both out of view in the close-up photo as the negative is in the shadow and the positive is out of sight and under the white battery tender cable.

Did you see this discussion here:
Hyper 1100 New Battery <img src="http://www.ducati.ms/forums/images/Ducati_ms_2015/smilies/tango_face_glasses.png" border="0" alt="" title="Nerd" class="inlineimg" />
Yep but I was looking for someone who has one in a watercooled Hyper as the battery is in a different spot & it’s a tight fit.

Ah, makes sense.
I wonder if this could be a solution on where to put the Rapid Bike EVO or PC5 (utilizing the space savings of the smaller battery).

Maybe with a really small one but most are similar size case to OEM.

I just ordered a WPS Featherweight Lithium battery for $115 shipped. Suppose to have a BMS built in to balance the cells. Not sure what type of over or under charge protection but my plan is to check the voltage before install & then just see how it does without charging & just monitor it via the LED gauge & the dash reading. Much cheaper than EarthX or an AntiGravity so I figured I’d test it out for the team:)

I've been pretty fascinated with the EarthX tech and they're local to me. Just haven't taken the jump yet.

How's the cold-weather cranking on them? Any issues similar to the lithium ones in cold weather?

I worked with the owner at Antigravity to develop a "soft" case around their battery to fit my 749R. Great battery and great customer support. If they are local that's just another reason to buy from them. Good luck.

Why are the numbers so different for the same battery?

I am Shorai on the 748S (~3 years) and BikeMaster on the 910R (~1.5 years). Both are on standard mini tenders. No issues. Both highly recommended.

The antigravity is lithium and the other is an AGM battery. The physical dimension are about the same. There is another battery from antigra it that has the exact output but is quite a bit smaller. The difference between the smaller one and the one I have is the protection circuit. The one I have has a "jump start " feature that turns off the battery if it gets below a certain voltage. The battery maintains just enough voltage to start the battery when you hit the bottom on the battery to reactivate it.

My Shorai died while it was on a Shorai charger. It was my third Shorai, all of which have died premature deaths while using the dedicated charger. which is $80 and only charges Shorai batteries.
I have a ST4S which does not seem to have charging issues. The Shorai always worked fine on trips. On one trip to Oregon/Idaho, I lost my clutch and had to go about 900 miles without one. The Shorai had enough juice to start my bike in gear which I had to do when I caught a light I could not run or make a right turn at and it was slightly or more uphill, so no Flintstoning in neutral to pop it into gear to start it.
My latest solution was to buy an Antigravity Battery with the jump start feature which I find appealing as it allegedly protects against over discharge.
I have an antigravity in a race car which is 3 or 4 years old and sits between seasons for six months but after that six months with no trickle charger, it fires up a 3.4 liter high compression Porsche race motor as though it just came off a charger. However, there is zero draw on the system when main electrical is switched off. The ST4S has some draw, the LED light on the dash blinks when the bike is off which I believe signifies the immobilizer is on.
I do use the Optimate charger at times, their trickle charger, .8 amps for Lithium batteries is about $58.00 delivered from Amazon. Unlike the Shorai charger, it will charge any lithium battery and serve as a tender.
I just put an antigravity in my KTM 500 EXC based on my experience with the car. It weighs 1.5 pounds but has twice the cranking power of the Yuasa that came with the bike.
