I received an email back from Alan at Deree... it turns out that they were having having a web site issue... shipping is now free so I grabbed a DBS-T head, which comes with a pill... I decided on the "new" XP-G2 pill that hits full power with a single cell (1X18650) and I should also be able to use my existing neutral and warm pills with 2x18650.
The best part: the XP-G2 pill will be domeless and neutral!!!
My Dereelight CL1H-T & DBS-T lego set will not be the cutting edge of technology, but it will hopefully be fun to mess around with...
