Some do but it's only because they don't understand the terms.

Well, I have been out of the loop for a while now with respect to newer bikes. Examples? I'm thinking they would likely be sport bikes where weight and size makes the biggest difference.

It would also be interesting to know if their charging systems have been optimized for the different battery chemistry.

They are great and some day all bikes will come with amazing powerful and light weight batteries like Honda's CFR1000 which comes stock with a HY110 ELIIY POWER LEP battery...

Of the aftermarket batteries I have looked at, Speed Cell seems to use the highest quality methods in their construction. Their customer service is also tops. Example: I bought a lightly used Speed Cell Legacy 5.0Ah. The seller had used it in his 2015 R1 for one race season before pulling it and setting it aside. It was on a shelf for nearly a year, not connected to a charger of any type. After I received it I sent it to Speed Cell just to double-check that things were okay. They ran it through their tests and I got it back in a few days. I have yet to hook it up due to our rainy season.

LiFePO4 batteries have very low self discharge rates, so sitting on a shelf for a year is unlikely to be a problem for them (unlike lead acid). However, the mAh capacity at low discharge rates is significantly lower than lead acid of the same "rating", so a parasitic draw will kill them significantly faster.

True. I've also read that when starting in cold conditions, manufacturers will recommend that you switch on your ignition for 10-15 seconds or so before actually thumbing that starter button.

Something about getting those electrons up and going...

They're certainly a little sluggish in the cold.

What I remember reading was a recommendation that you crank it a little, wait 30 seconds, crank it a little.

The battery needs heat in it if you want it to work well. When just running lights, the internal resistance of the battery is a very small % of the total resistance. When running the starter, the internal resistance is a significant % of the total resistance.

When it's cold, it'll crank harder the second time than the first, and even harder the third time.

Whoa... Speed Cell has come a long way since their first LEP batteries back in 2009...

Speed Cell size and weight comparison...

I've had a Shorai in my ZX14 and my KTM 450EXC for several years. No problems at all. I do have the Shorai charger, In fact the KTM is sitting up at my house with the charger hooked up in the "Storage" mode right now.

Interesting.

Do you know if the VRR is the same as previous models with lead/acid batteries? Or is it a new VRR designed specifically for lithium ion batteries?

No worries here, I didn't think you were.
in this cause I think it was just a bad unit. Anti-gravity warranty it, but did have to fight for it.

My bike needs me plan and simple... who else will spend the time and patients

there's not enough RC45s world wide for them to bother with... so it's up to my
