The short answer is you shouldn't use a charger which has a desulfation mode like the C-Tek (I have one of them too which I now only use on lead-acid batteries)
A charger like the 'Battery Tender' brand which does not have a desulfation mode is ok and my mate uses this on his bike with a Shorai LiFePo4 battery.
The problem is that if the battery does not have its own Battery Management System (BMS) which is a set of circuitry that is able to monitor while charging the individual cells of the battery to prevent over charging, over discharging or short-circuiting then using a standard tender like the 'Battery Tender' brand of chargers will be OK but will not be able to balance and monitor the charging to the cells individually as your just sending a single current to the battery (which is what your alternator/rectifier is doing anyway).
That is why Brands like Shorai have their own battery charger which is a BMS whereas some brands have this built into the battery (cant remember which ones as its been a long time since researching this topic).
I had my shorai on a 'Battery Tender' for over a year with no problems before I bought their BMS charger as it was on sale.
If you tell me what brand of battery you have I may be able to help you further.
