I am seeing temps of about 120-125 deg normally. the problem with inducing external heat, is that you need to get into the cells. And that can take a while trying to push heat through the case and into the cell. think about cooking something. have you ever cooked thick burger on the grill at too high of a heat? the char the outside and leave the center raw. Same principle. can you add heat to the pack for a long time to bring the temps up sure, takes longer and....if you already charger your pack, then add heat, the voltage can creep up and cause other issues. But the cycle method generates here directly where you want it..into the cells. and voltage is controlled by the icharger so no creep. They say you need to leave the packs at 72 deg for 1-2 hours to allow the heat to become even for battery testing and comparison. If I check my IR at 80deg and you check yours at 65, our numbers mean nothing. for like for like comparing, you need to create a baseline env. Typically that is around 72.
