I charge my IB4200 at 6.0A linear and 6mV delta peak.
I dishcarge my pack by zero-v mode on CTX-D before charge as Nexus recommended few page before. I think this way of discharging helps putting more capacity(200mAh+
) to my batteries!
It's winter here in Korea now, so I warm up my batteries before charging.
I made my own battery warmers that can store 3packs.
It is connected to Tire cooker of CTX-W. Maybe you guys could use your bar type tire wamers as battery warmers.
Then I move my battery pack to Warming Tray. (set 30~40deg.C on Cell master), then start charge.
My target temperatue when the charge terminated by peak cut, is 50~52deg.C.
You may feel some lack of power from new 4200 cells. But after 3-4 runs, power gets higher !

We just haven't tested or gotten any feedback on IB4200 setups yet, so we have not been able to list any on the site.
You probably can't go wrong with a linear charge on the IB4200. These cells apparantly have so much power AND run-time already. When it gets to the point where you have 200+ seconds of run-time left on a pack after a race, a CTX setup may not be giving you anything.
Perhaps Ryan Lee can give some insight on how he is charging his MMR IB4200 batteries
