I agree with your friends was right about trickle chargers for lead batteries.
you use one provided it has no desulfation stage and has a charging voltage which goes above 14v. You should also disconnect it once the battery is charged which is quick with the general 2.4ah capacity LFP’s fitted to bikes.
An lfp charger would have better stages as kidnplay listed.

cell balancing can only be done on batteries with BMS which is often omitted from charger brochures. Fortunately most curre generation batteries have it. Shorai is a different story and cell balancing is done with their dedicated charger.

BMS reset is nothing more than forcing the charger into action even if there is 0v at the battery terminals. You can do the same by connecting a spare battery in parallel before attaching the charger

If you have a lithium battery there is no need for a trickle charger. If your battery is dead, the trickle charger you normaly use to charge works just fine (just like you don't need to switch out your bikes alternator). But unlike lead acid batteries, which leak over time and like to be stored at 100%, this is not true with lithium batteries. Optimally they are stored at more like 60%, but it would take a couple years for them to leak to that level, if at all. I've had my shories since 2011 and they are still working perfectly, I've never had to charge either on e of them (track or road bike). Don't worry about it.

Question:
Is trickle charging good for a Lithium battery? An informed friend tells me it's not.
What has been your experience with these batt's? I suppose owners of '17 and '18 SP models from when they were released, should have a few years of experience they can share..?

I like the USB connector btw, prolly going to buy one for my iPhone.
The correct Lithium battery maintenance charger will work plugged in 24/7. (y)

I have 2 Optimates - 1 for the Super that has a Firepower Featherweight battery and on for the street bike with the OEM battery.

Both plugged in 24/7 and they cycle through their maintenance modes automatically.

Unfortunately the SC77 and newer digital bikes will be a disappointing drain in the battery if not ridden regularly as just sitting at Starbucks (or at home entertaining yourself) cycling through the TFT dash menu options repeatedly and showing your friends all the features without running the bike can be enough to knock the edge off the battery charge.

Get the battery below about 11.2v and all sorts of electronic fuckery starts occurring. ;)

You really do need to keep these bikes on proper maintenance trickle charge if you want a flawless ownership experience (y)

Definitely. And more so for the UK and Euro bikes with their H.I.S.S (Honda Ignition Security System) immobiliser which does place a permanent drain on the battery. Like many, I wouldn't leave my bikes without hook up to battery tenders, with the consequence being that I am a major drain on UK's national power grid!! :eek:

Ah, our friend @bonjo sounds as if he has a degree in electronics and circuitry! I can't even use a multi-meter:(.
Your educated guess is correct(y). We are not all perfect. I still don't understand fareinheit, feet, inches pounds, onces, etc,etc,etc:)
Honda HISS is quite clever, I measured the drain on mine and after 24hrs and 0.1v drop on at the battery; I think it shuts down until the ignition ON cycle. If you have an LED HISS blinker, set it to off or like me OFF after 24hrs

A dedicated LFP charger would stop charging and the monitoring alogarythm is different lead bat chargers

I have literally ridden maybe 40 miles in the last 3 months between 3 bikes. All have Lithium batteries, and I am still pleasantly surprised they fire up almost like reading my mind - seems like the momemt I touch the switch, they are on.

Enjoy it while you can ;) Spend more time in the dash menus mucking about and watch those happy 12 volts diminish pretty quickly :ROFLMAO:
