Ric, that extension tube would be very useful and I think you would sell many to those who already own the BTU Shocker.
I created a survey that gained a lot of interest but you never supported us. Why not? Can you please make this happen for us and start making the extension tubes and 6 x 18650 carrier?
Here’s a pic with stacked BTU battery tubes.
