Brent, what advantage do you get from the 580 vs the std 710? I get headroom of 32% on a TP 5s 2800 battery with my BA 710's pulling a 65oz plane with plenty of power. More than I can use. How much extra battery with the 580 and is the power that much better?

Here is a little info on the topic of advantages and challenges of the Li-ion 6S 2600/2800 versus the Thunder Power 5s LiPo 2800 battery. This is info from my reading on the topic and pestering of battery makers like Dane, and inquiring with the vanguard of guys using these in stunt, ie Paul Walker, Chris Cox, Joe Daly, ect
Advantages:
- 6S punch
- Weight is about the same +/- 10g or so
- You get, potentially, a thousand charge cycles per pack.
- You can discharge much deeper without damage.
- Discharge curve is flatter and longer than Lipo.
- Somewhat lower chance of burning your house down vs LiPo.
Li-ion Disadvantages:
- Packs harder to source
- DIY may be required.
- Limited to fewer mAh options. 2600,2800 in 18650 Molicell or 4200,4500 in 21700.
- Li-ion runs a bit warm, so adequate cooling must be part of the design.
- Li-ion has higher internal resistance, which may or may not matter all that much.
- Li-ion is not for ultra high amp draw use like FPV racing. Control line stunt really doesn't tax these very much, especially at 6S.
- Li-ion charges at a slower rate than LiPo. 1C charge rate (-ish)
