If money were no object, what hump battery pack that provides the best performance for savage xl that will fit? What starter box should I use regardless of budget for the savage xl? I also need a great battery charger regardless of budget. I want to get rid of roto start on the savage. Thanks for any advice.

If you want electric start, your pretty much stuck with a roto of some sort on the savage. Otherwise, it's pull-start. The flywheel isn't exposed for a bump start.
The best receiver pack type would probably be a 2S LiPo with a BEC that drops the volts down to 6V, unless you have electronics that can handle 7V+. Short of that, the cheap intelect 1600mah 2/3A hump packs work fine for me. If you go with LiPo, you will need a LiPo charger. If not, there's no need to go nuts with a NiMH charger as you don't want to really charge a receiver pack at more than 1A anyway. Either way you go, it's not a "money is no object" kind of thing because the packs are small, so they don't cost much and a charger that can charge either battery type at 1A or 1C also doesn't cost much.
There are quite a few traditional NiMH hump packs here:

Appears they include a few LiPo packs as well. I don't know what LiPo will fit, but pretty much any 2/3A NiMH "hump" pack will fit in a savage receiver box.
This BEC will have plenty of current to drive two servos, but it requires the $20 castle link to adjust the output voltage:

Remember though, a bec is only needed if your wanting to use a LiPo pack.
Or, you can go with a cheaper generic BEC that has a voltage pin on it. I use a cheap one in my stampede because the castle esc only puts out 5v. Something like that won't handle dual high power digital servos at full capacity.
A charger like these would work for either NiMH or LiPo:

Or you can find something more economical that is type specific.

I just bought some life packs.
https://hobbyking.com/en_us/turnigy-nano-tech-1700mah-2s1p-20-40c-lifepo4-receiver-pack.html
So far pretty satisfied. I gave up on NiMH hump packs.

Forgot about those. They have lower charged voltage than LiPo. Don't those charge to 7.2V when fully charged though? Still a bit hot for a receiver/servo that is built for 6V. Do you run a BEC or voltage regulator?

They only charge to 6.6v. I don't run bec or regulator.

I see. I thought they topped out at 3.65V per cell (7.3V for 2S), which at full charge would be a bit high for a circuit expecting 6V.
