Overheating shouldn't be an issue, if using a charger that can deliver the amps needed without the variac. In Mex's example, he is using the HF charger that has a 10 amp charging circuit. If using the BCI formula of 5% current, that is almost smack on for two 6v GC2 batteries and within the capability of the charger.
I use a variable autotransformer regularly. They can be used for other things too. Here's one I cobbled from a 240 double gang, I cut the shaft and made two 120v variable transformers:
