Yes it can. I’ve had no problems with heat charging 2x18650 cells, or 2x14500 ones. Both times they come off at 4.21, and settle to 4.19/4.2. Slower than my 4Sevens (but that can only handle one cell at a time, and charges to 4.13), but I’m very happy - if it’s good enough for HKJ, it’s good enough for me.
