What to do with the battery

I picked up a Li Ion battery which I love. Should I yank that thing and put it on my workbench in the house on the charger for the winter, or just hook up the charger in the freezing garage for the winter?

LiFePO4 hold a full charge for up to 12 months. Simply charge it, or not (charge it later, when ready) and keep it in a safe place until the riding season starts. No need to trickle charge it, these batteries are good - as long as you don't use a charger with de-sulphurising!

The worst thing about these batteries is if you let it get too flat - sometimes they don't recover. If you need to know anything else about LiFePO4 batteries, just ask...

Safest place is in the bike, right?

I'm curious as to which brand Li-Ion battery you bought, and how well it mounted under the seat. I have a couple of Shorai batteries in my modest collection of bikes, and have been very pleased with them, despite their higher initial cost. I was going to put one in the GRiSO, but due to that bikes unusual battery "clamp" I decided against it and stuck with the AGM style. As far as cold weather is concerned, I know the biggest complaint against Li-Ion batteries (Li-Iron, really, I think) is they don't like to crank over in cold weather. You have to "pre-heat" the battery with the lights on or similar for a few minutes to get the electrons flowing in the cold. Doubt if I would use one on a full-on touring bike that might sit out in the cold overnight on a trip somewhere. I did buy one of those small "micro-start" battery kits that I carry with me on overnights trips, just in case a cold snap gives me battery troubles. Here's the one I use: [You must be registered and logged in to see this link.] I just take it into my room on an overnight on a bike with a Li-Ion battery. They are pretty slick, and will even start a car! Cold thick oil and a cold battery can be a frustrating morning.
