It’s a question of how long it’s useful. Sitting voltage versus the sag voltage. While TommyDee has proven with his many tiny IH designs, you can make something very useful with less battery power, 3 - 18650’s give a decent amount of use before you need to recharge. 2 batteries or less, the more you will be recharging. This of course is directly related to the batteries AMP rating. A lot of IH’s are using LIPO packs too. Bottom line if you care about less time before a recharge, keep an eye on the overall mAh rating of the pack and it’s ability to deliver the needed power. TD can add....Flux delux uses three batteries. Flix plug in.
Is the idea possible for an induction device to work only using 1-2 batteries or 1-2 batteries simply isn’t powerful enough?
I’m not a continuous smoker That’s why I’m wondering.
