Default Receiver Battery for HB D8, Recommendations

Im building my Hot Bodies Hara Edition D8 and I would like to know what type of receiver batteries people are running.
Im thinking of going with a Lipo battery but i haven't found one with a hump design and im also finding that they require a regulator to bring them down to 6.0 V.

a regular 5 cell NiMH hump pack will fit just fine.

for lipo the only one that will fit without modification is the Robitronic 1500mah lipo pack.

you dont have to use a voltage regulator if your servos are rated for high voltage use

i just use the nimh pack and it works fine for me

Orion makes a Marathon 1100 Mah 30c LiFe that fits like a glove. With LiFe, its 6.6v and no worries about regulators or dangerous puffing, fires, etc.

Personally, i use a 1.450mah long LIFE mounted outside of the stock battery box, but a friend has been using this Team Orion 1.100mah LIFE batt for couple months without problem, straight fit no mods required :

If you want LiPo, the Robotronic is a drop in: fits with ZERO modifications in the D8 battery box.

Here's a shot of it in my D8 (the other pack is a modified Common Sense):

LIPO or LIFE?

I find that hard to believe. Can you get the cover on with the 1900? Not saying it wont fit but do you have a pic? I have the Marathon 1600-1700 and the 1900. I would go out and try it myself but my 1900 is at a friends house.

i have had to drimmel the inside of the top lid.

you can test the top lid by trying to put it on the 1900 cell pack then drimmel some more.

I have also had to make a small hole in the tray for the cables to stick outside.

will take photo.s tomorrow and post

Can someone explain to me why Reedy Life batteries (6.6v) do not require regulators? If the servo's max out at 6.0 v, wouldn't the extra voltage cause damage?

from what I understand you do not need a voltage regulator using life packs. Only lipo with non HV servos
