[QUOTE=steamer861]I ordered another one myself I'm anticipating putting a DNA75 in it, with an 18650 battery sled I plan on modding the back cover with some magnets, I will be settling for only 75 watts but gaining the convince of a replaceable cell I don't regularly vape over 50 watts But really like the big watt preheat punch from the DNA200. I guess I will see how it works out with only a 75 watt board, when there available Sounds like a good idea. Do you think a dual 18650 battery sled would fit? You know two 18650 in parallel. [QUOTE=steamer861]Right now I'm going to try older Firmware to see if I could get it to operate normally, If not I will get in touch with Evolv to see If they will RMA it [/QUOTE] Nothing happened with older firmware, eh?
