Non CM rom/kernel with MHL & Fastcharge?

HI - posted this in the question thread, but didn't get any help;

I have an i9505 and have rooted it to use with a Pioneer Appradio and ARunchained

All works perfectly, except MHL drains the battery faster than it charges via a 2A charger. I've been pointed towards a fast charge kernel as the solution to my issue, but the threads for the head unit online are all a couple of years old, so the kernels and roms are all now out of support.

Can anyone point me toward a kernel and rom (if a rom is essential too?) that supports MHL and fastcharge? (i've been warned away from Cyanogen because of MHL issues)

Thanks!

ROM/kernel recommendation

I was think of flashing a new ROM and kernel and im not sure which one to choose. What stable ROM and kernel would you reccomend for signal, performance, and battery life (in order of important).
