Cold temp lithium battery replacement/ bendix problem?
« on: May 29, 2020, 07:46:04 PM »
2017 sherco 300ser. I do ice racing in the winter in New York where it it sometime -10F degrees. Summers also can get up to 90F degrees. What are my best options for a replacement litium battery I could run all year long? Also can anyone describe the symptoms of the failing starter bendix? Part is kinda pricey and I dont want to replace it unless I know I have to. Thanks

You won't find a reliable lithium battery for -10 degrees. If you really want a lithium battery, you'll need to keep it warm somehow until you have started the bike.

Thats kinda what I thought. I can manage to keep it warm. Do you have a recommendation a lithium battery in general? I read that some guys had bought litium batteries that wouldnt turn their bikes over.

My '19 factory 300F comes with a Lithium, but I have no idea what brand or size it is. I only see it sitting in the bottom of the airbox when I do the filter.
Previous bike was a Husky TE310 and I ran an SSB powersports lithium in that. It was 140CCA and seemed to do the job fine. You can get 230CCA versions in the same physical size now.
If you get a lithium, make sure the CCA is at least the same as a Lead/Acid, preferably a step more.
The thing I didn't know and killed a couple of lithium's early is they do NOT like a normal lead external charger. Specifically, the disulphate bit at the start. Like you get from a good CTek charger. A plain old dumb charger that pumps out 13.4v 1amp is better but the bike's alternator is best.

The best way to check the bendix is to pull the stator caver off and pull the piece out. I didn't know mine was bad until i pulled it out and found that a large number of teeth were chewed pretty bad. Back then Clay was selling the updated part for a very discounted price, but not sure how it works now.

I use a lead acid battery in the winter and I haven't had any problems. I only just switched to a LiFePO4 for summer use. When the bendix fails you will hear the starter just free spinning and not turning the bike over.

I've been running the SSB 220cca in my KTM & sherco for a few years now, my batteryologist said 220cca was the best  size ;)
