So far so good on my Earthx ETX 24C.  I also picked up the Jump Pack.  With the Battery Management System not allowing a discharge below 9 volts, and the ability to give it a quick jump from the battery pack if I ever goof up and leave the bike on, I think I will be starting my ride for a long time.  Not a cheap solution, but neither is getting stranded.  I'll continue to test.

There are some Youtube videos showing Snowmobiles starting at -35 deg.  The Snow mobiles reviews are raving about the cold weather performance.

It looks like they only call for the ETX 18 for our connies !!

Are the earthx as light as the shorai's ??

It was so light, it almost seemed like an empty case. I didn't have a Shorai to compare. The weight is mentioned in another post and on their web site.

The website lists the base battery. I asked about options and got this answer.  I upgraded and the  ETX24C fit perfectly for the base and needed a bit of foam filler that they provide to make up some extra space on the top. This choice has double ah rating of the stock C-14 battery.

Thank you for you inquiry and the battery you need is the ETX18C, or if you want to upgrade, the ETX24C or ERX36C.

So far hows the performance in the cold ??

Rode four times so far with temps in the forties. Cranks really hard with no warmup needed. I won't be riding in the single or negative digits, but the snow mobile riders are saying this battery built with zero moisture works well in the cold. It does crank noticeably faster.

Awesome !! So i guess the only neg is forgetting something powered on and voltage dropping to 9V ??

Discharging any battery is a negative. With the Battery Management System the battery will turn off at 9 volts and will live on after a charge or a jump. This differs from the destroyed Lithiums that Cuda was talking about that get discharged and damaged. Lead acids also get damaged during a deep discharge.

I suggest reading though their website. This is not the normal lithium battery because of the advantages of the BMS with regards to dischrage, over charge, over cranking, and balancing the cells during charging.

Yes its sounds like a nice system. The Jump pack they also sell is not designed to jump these batteries, so i guess you'd need to remove the battery and have the optimate charger with you to get going again ??

AD, you are asking the same questions I had about this new battery technology. I researched before jumping into this just like you.

The Jump Pack will start the motorcycle when the battery drops into protection mode at 9 Volts.    That is the purpose of the Jump Pack, but it also powers and chargers USB devices as well.

For charging in that condition,  Optimate makes a model 471 charger that Earthx sells on their web site that is designed to work with the BMS system and reset the battery. Any charger will work, but the catch is, some chargers will not start charging a completely dead battery which is what the charger will see with the BMS Activated.  They provide instructions for using these standard chargers, and basically you need to put a battery in parallel (like the Jump Pack) for the charger to detect a voltage.  At that point the BMS will turn off and allow the current to flow back into the battery from the charger.

The Jump Pack in addition to starting the motorcycle, will also provide this voltage to use the charger. Like I said, the Optimate 471 will reset the battery automatically.

I asked this question also the same lines and this is what Earthx said:

Thank you for the question.
 
Yes, the EarthX Jump Pack would be able to start the motorcycle in the event your ETX24C is shut down due to an over discharge. That is an additional benefit of the use of the Lithium Iron Phosphate cell vs. the Lithium Cobalt cells our competitors are using. Our jump pack is at 13.3V and can start a motorcycle if needed whereas the Lithium Cobalt is only 11.7V and cannot do it.
