I totally understand about going to 18 cells because it will be a bit harder on the controller having already burnt one already.
Running my G-Maxx, I have only used 18 cells.
I have done about a dozen runs or so. I usually run it full throttle especially when I am a big grassy area, dirt area or field.
Only times I couldn't was because something broke especially the pinions, LOL..
My last run lasted me about 4-6 mins because it was almost all full throtlle going around in a huge field. I am still waiting on my custom hardened steel mod 1 gears which I should have very soon. (I might try to get mod1 spurs made in a plastic but that is just a maybe)
(Before I start, I know that these figures are not nominal or avg but more peak or max)
I used to think that at 18 cells vs 16 cells (21.6 volts vs 19.2 volts) equated to 83.33 amps vs 93.75 amps which I thought at 18 cells it would run cooler. But I got an email from Plettenberg telling me that I wasn't thinking correctly regarding this. That at 18 cells the BigMaxximum would pull 1800 watts vs 1600 watts on 16 cells. So in regards to that, you were correct in thinking of 16 cells would run cooler than running 18 cells because it would have to handle less power, but then I thought maybe using 18 cells might be harder on the controller in one aspect but heat and amperage would be better distributed over 18 cells than 16 or less cells meaning it would be a bit more stable. Maybe I am wrong and soon I might burn a controller but I haven't so far and I don't even run a fan even if I do have one mounted under the Schulze hehe.
Anyhow from all the runs, I think it will hold up well with 18 as long as I don't gear it to the moon.
By the way I mentioned the 2230 only for the weight but I did say the 22 series which if you really wanted more powerful motors to look into the 2240s and 2250 which would pull over 2000 watts, I haven't looked at BK's/Lehner's site for specs.
I know Rene likes the 7XL and it is a good motor for the cost but I like my BigMaxximum. Did you know that the 7XL is a bit heavier and if you took off the fan off the BigMaxximum that its shorter than the 7XL naturally?
Titanium screws.. hehe.. I thought about that..
How do you like your Aitronics 358?? U know it is a great servo but I can't get over the fact that the HRS 5995TG that now I am using in my Juggy Project has twice as more torque with almost similar speed. Crazy!! But I did give my Juggy 358 to my G-Maxx which works very well tho I would like longer throws in my steering. Do you know if you can adjust end points of servos using the servo programmer on analog servos?
