So is it safe to say that my DuraTrax Onyx 240 would not be appropriate for charging these types of packs then?
Would this hobbico.com/chargers/hcam3005.html not be a good item to have in my field box then sense peak charging shortens life span of batteries?
If neither of those chargers are good for what Ineed would it be better to ask this, based on my needs what battery pack would be best for the Hitech Optima 7ch Rx and what charger would be best (without breakign the bank on a nother charger and could MAYBE be integrated into my field box) to charge the suggested battery pack?

Hop im not being to difficult with all of this.
