put some Fromeco Lithium Ion 5200 packs in the nose.. they are almost the same weight as the A123 pack.. you can charge them at 1C in the jet.. Have done it for years.. Thats my preferred setup with a regulator. High capacity, good Impedence. easy peasy to charge..
Call them and tell them what config and how long of wire and what plug.. I usually get them in a 2x2 long stick with 12 inches and a Deans.
No balancing required.
IFyou are not using regulators, then A123's or recently I started using BUDDY RC Life Packs.. you must balance charge A123/Life every time however.. If you balance charge and check them every time, you will be fine.. I did a lot and I mean a lot of testing on A123's back in the day.. they are insidious about getting out of balance due to the flat discharge curve..
Bottom line go with something you understand and are comfortable with..
I have to disagree with you on this one as Lions are about the only battery technology I won't use anymore. They simply have the lowest C ratings of any of the battery technologies that we currently use and take forever to recharge compared to A123s. I'm sure they would be fine for a jet as they don't draw nearly as much as a typical giant scale aerobatics plane but since they charge so slowly and I need to run such BIG packs in order for LIONS to cover the demands of a giant scale aerobatics airplane I stopped using them a long time ago..
