Check the manufactures recommendations. I know my Shoria can as long as it's not decalsification/pulse charger.

Yes do some research...... I've seen a couple of video's on Google that explain the difference in the charging algorithm's between AGM and Li Ion batteries. They said you can use a normal charger but that it needed to be watched and also that some AGM smart chargers would 'think' the battery was fully charged or dead and not activate.

You're best off with a dedicated Li Ion charger - eg a Shorai battery has a 3rd plug designed into it's case for it's charger which has a function that balances the cells, and also keeps a stored battery at 60% (if I recall correctly). Li Ion batteries should not be stored fully charged or left on a battery tender as they may catch fire if one or two cells become over charged.

There's a video made by a bike riding electrician showing what happens to a cheap type Li ion battery with unbalanced cells on an ordinary charger (think boom and burn)......... (y) Maybe newer Li Ion's have addressed this cell balancing issue and it's no longer a danger........ :unsure:

I have several bikes and found this charger to be useful as I have lead acid and lithium batteries.
Lithium batteries can die on you over the winter if not on a tender and usually cannot be brought back to life with a trickle charger like the one I showed. You would need to put it on a 10amp charger for a very short period and it will come back to life.
