I have switched over to LiFe batteries and they are superior to all other types in my opinion. Steve at NoBS is an expert in the industry, there is a difference between A123's and LiFe type batteries. Here is the question to ask; is my plane worth the extra cost of good batteries?

Just a refresher: LiFE batteries do not have as much energy density as Lithium Polymer. If you are talking about batteries to power your motor, you need more cells/weight with LiFe to achieve the same power output. For those of us that fly 'large' electrics, LiFe batteries do not make sense to use for power other than Rx power.
