Hey all, I've tried finding info on this but to no avail...

I currently have a Shorai on my Multi but due to moving to a bit colder area, I'll have to use heated gear. At 2-3AM, due to the cold, my bike will barely kick over. I'm wondering if adding the additional load from the heated gear will tip it over the edge...am I better off replacing it with the stock Yaesu?

As you can tell, I don't know a lot about electricity...sorry.

Thank you!!!

Well, once it starts, you are running off the alternator. As for the warm up below 30 degrees F, Shorai recommends that you turn the key on to let the headlight shine for 30 seconds - "to warm up the battery", whatever that means, so I think you will be ok with the accessory heaters. Good ones have fuses,..

The Stock battery lasted for how long?
5 years is a good battery life and I change them out for peace of mind rather than letting them die an untimely death.

Hook heated gear up directly to the battery, with appropriate fuse, (with controller)
No problem!
I will shut down the heated gear a couple of miles before destination, again for peace of mind, and may even run the bike a bit before shutting down (3000 rpm will make lotsa juice to charge the battery ???)
Hey you can even get a battery (pocket size ) for walking about with the heated gear!
Gerbings has whatever you will need. They make heated gear for the military (so I have heard)
Battery technology has jumped leaps and bounds!
Stock is still very OK.

This is what happened to the Shorai in my dirt bike. Had one in my wife's F650GS also, and replacing seems to have fixed some intermittent stalling issues. I'm not likely to buy another one

Ouch. How old was it before it did this? Any luck having Shorai reimburse you? This makes me a bit wary of the one i have in my monster.

I have been using Shorai batteries in my Tuono, Multi 1200 and TNT 1130 for the past 4 years without any issues, we get down to close to 0 deg C in Tokyo in winter, and they will crank a bit slow then but turn on the light for a bit or crank over then wait a minute before next try and they always work fine. No problems with heated gear so far

Probably 18mths old. They suggested it was caused by overcharging. Not sure how a 450 dirt bike could do that

Bad voltage regulator. Japanese bikes seem to have a lot of problems with regulators, especially Honda.
It's neither a Honda or Japanese but the regulator could be. In any case the new (AGM) battery hasn't given me any issues (yet!) so I'm happy and hoping it stays that way 😉

Let me just add that I realize it could be a one off, or it could indeed be a problem with the bike overcharging. I don't want a battery under my ass full of lithium and whatever other chemicals are in that mix, which could burst like the one in the pic is threatening to. As far as I know, AGM batts are no risk of covering your ass in chemicals from overcharging?

With Lithium, it's not the chemicals that would hurt, it's the explosion and fire.

Cheers!

Im not really a fan of the shorai either, not sure i would buy another. I had one in my multi and once the cooler weather come on it would not start in the morning ever. The "warmup" procedure did nothing. leaving it on a tender did nothing as well( i suspect i need their special one). I ended up pulling it out and put a stock replacement battery in. That one works a lot better for me.

I have on in my TW200 as well and same deal with that bike although that one the battery will go dead in about a week of sitting in the cold. when i say dead i mean stone cold dead, wont even light the headlight or dash lights. Thankfully i have a kickstart on this bike, i have needed it quite a bit with this shorai. There is no current draw on this bike so its def the battery, i have gone as far as unhooking it and same deal. The other TW we own that my girlfriend rides can sit for a month or more and the Exide AGM that it has in it will crank it right over. I plan on getting an exide for mine too since it seems to be a lot more reliable.
