Just in case anyone was wondering. Factory battery vs Shorai lithium for yz250fx

[BOAB]

Are you surprised?  I'm not. ?

The lithium batteries are great for saving weight. If you're riding in cold temperatures, less than 40°F, they will not work.

Mine works just fine below 40

Mine doesn't. Power substantially falls off in cold weather.

So what is the best light weight battery? I don't ride a lot in cold, but I sure don't want to deal with that when i do. My factory battery seemed to be getting weakwhich is why I made the switch.

I've been using Anti-Gravity batteries for years... Never had a problem in the cold... I run two different size models, the AG-801 and the even lighter XPS SC1, both have 100s of hours on them...

Do the Shorai batteries still catch on fire ?

I bought a Tusk lithium recently to replace my lead battery in my KTM. Cost $70.  Light as a feather too.  Starting power definitely increased when it's 50-70 degrees.  Below 40 degrees it suddenly takes about 8-10 start cycles of a couple seconds each to get the battery warm and strong.  Then it fires up no problem from that point on.  The more you use the Les lithium batteries the stronger they get.  Recharge time is super quick too.

Melted cases is usually what happened.  We used to buy them from Battery's Plus Bulbs and they quit carrying them because of the return rate. They worked with another supplier to make a "safe" case, they now sell under their own brand.   Anti Gravity used to use the best quality lithium cells, Japan vs. China.  My advice with lithium is buy the best warranty and save all your paperwork.

My shorai is three years old and has seen 250+hours of use, including winter riding. It has always functioned perfectly and has never been on a charger. I don't ride in temps below 30f very often.

I bought a Shorai for my CRF 250X for this very reason and I'm really happy with the battery's performance too. If anyone is looking to shed a few pounds, this is the best way.
