Yup Wayne, respectfully, it was just my opinion for what its worth..

Most of my planes have A123/Life packs.
Yes Life's charge faster and are much more convenient, but if I have to bury the packs with a regulator, it is the proven safest power system.
If I had to bury packs without a regulator, then the 2300 A123 is a preferred. But I still like to be able to touch them for warmth, or smell them if they vent.. I have had about 6 cells vent over the years. but since I started using higher quality balance chargers, Life's have been perfect.

You pointed out the downsides of course.. everything is a tradeoff as you know.

If using Life's or A123's for buried packs, then suggest to Jetpilot24 to ditch the regulator, it isn't needed. Lots of ways to skin the cat, Thats why I really Like the Jeti CB200. and the spectrum Powersafe receivers..
