To make an extension to fit on the existing tube we still need to increase the diameter buddy. It has to go at 18mm
I can see how that would increase the diameter of the device. In lieu of a telescope. would it be possible to instead make an extension accessory tube to allow for the extension to a 14650 battery for those who do not mind a longer PV? This would allow for the diameter to stay within specs for the Penelope, meet the need for the 14500 crowd and also allow for the use of the 14650 for prolonged battery life for those who do not mind a longer form factor?
