Buying a bike with a lithium battery. I know they can be more finicky than lead batteries. Any opinions on the trickle chargers? Recommendations?
 
Not really needed for the most part. How long do you plan on not riding? Lithium cells discharge much less than lead acid
 
I like the optimate brand. I don’t leave it on the battery, I charge it up once a month or so, take em off the charger after it tops off. I read some where that lithium ion batteries don’t like constant recharging, but my guess is a specific charger for lithium ion batteries, it would be fine to leave it on a charger. I got the $40 lithium ion specific charger, but they have fancier ones if you want to spend more money.

I agree with R3DS!X. If you ride the bike a couple times a week, you probably won't need a charger. The Lithium battery in my FZ-1 is now 8 years old, holds a charge fine, and has never been on a charger. It gets ridden one or two times a week.
 
Lithium’s are great for sitting, their self discharge is incredibly low compared to lead acid
 
I have a generic lithium battery tender for my earthx battery, i think the shorai batteries void the warranty of you don't use their charger. Bikemaster is the brand of mine, I only leave it on until the status light comes on at full charge, and that is only every couple of weeks.

From Shorai
LFX™ batteries should be recharged whenever voltage drops to 13.1 volts, or sooner. If you have a vintage, custom, or off-road vehicle which has NO draw on the battery when key is OFF, then you should only need to charge your LFX™ battery once a year. However, most modern street bikes have a draw even when key is off, to support clock, computer, alarms, or other devices. This draw will eventually drain the battery, which is damaging and could void your warranty. So if you are not riding twice a month, then you should charge the battery every few weeks. “Smart” lead-acid chargers with automatic cutoff may be used for periodic charging, but will NOT work as a tender/maintainer and should be disconnected immediately after charge has finished. Older lead chargers without automatic shut-off should never be used. Improper charging is dangerous and will void your warranty. A Shorai BMS Charger - with Store Mode - is highly recommended for anyone who rides less than twice a month. Alternatively, you may disconnect the negative cable from the battery for storage, and charge once per year in that case.
 
I broke down and bought a Shori dedicated charger. No battery problems since I went that route.
 
I am using generic charger tender I got 15 years ago. About 9 years ago I switched to lithium batteries and no problems. One on street bike, one on dirt bike.
Basically you dont need tender unless you plan non riding for a long time
 
Yeah same here. I use a cheap generic tender on my lead acid and lithium batteries, but only if I dont ride for a while.

The lithium batteries seem to not lose any power at all even when sitting for 1-2 months. I have a Bikemaster one in my Ninja 300.
 
I talked to a shorai rep at a show and he said my battery tender jr will work on it and ive had no problems
 
All energy packed in storage presents some risk and Lithium-ion batteries
have about seven times the energy density of traditional lead-acid
batteries, which means you can get much more power from a much
smaller-and lighter-battery pack. As with any new, unfamiliar
technologies, lithium~ion batteries have spawned various alarmist
views but used properly, they're superior to their old lead-acid
predecessors.
