Is there an electronic wizard able to explain why, if a lithium-iron battery is able to cope with being charged by a motorcycle’s electrical system, it requires a special mains charger?
Charging Lithium-iron

Correct me if I am wrong but AFAIK, the main problem is a mains charger with a "recondition" function which "pulse" charges at 16 volts.
This is too high for a lithium battery and will cause overheating and possible fire.
Most bike lithium batteries have an inbuilt Voltage (or charge) Regulator to drop the bikes output down from 14+ volts to 13.2 or something like that which is ideal for lithium batteries.
To the best of my knowledge, a standard (non multi-stage) old fashioned battery charger should be fine if the lithium battery has an inbuilt regulator.
I believe that even the inbuilt regulators in the lithium batteries cannot handle the "recondition" function.

Ah! Thank you Macka and ARKNT. That makes perfect sense. Thank you both for taking the time to reply. I am alright, as I bought my battery charger in 1972.

I have a Litium Battery on my bike and there's no problem with the bike's charging system. Don't use a modern smart charger as the "Sulphate mode" will destroy the battery. Just use a real old fashioned charger or one where you can turn off the "Smart charging".

I have one of these battery tenders that handle both, but as John states above, it's the sulphate mode that is the problem.
