Yep to Dick and Josey,
I'm not familiar with the intellect pack. I'm happy with my small battery pack from NoBS Batteries so far. They are low impedance and can be used for ignitions. There is always room for improvement. Where do I find the intellect packs?
I have not used the lipo/reg combination because of reasons stated by Dick Hanson. I would go with the 4.8 and instead of a regulator put the money toward a optical kill switch (option). IMO..... Bill
