Want to put 2x 9v in it but curious if it could handle it. Anyone ever done it and do u think it's a good idea ? Or is there anything else I should do to it.

It's explained in here.. Along with several other modifications.

This ^^^ - I was just about to do the same thing - so I'll take it 1 step further:

Yes this is how the mod gos together so don't ask why do I connect the reds to the black and vise verse. If you do it as I tell you then there wont be any issues.

This is a very easy mod to so its very hard to screw up.

There has been some cases where this mod has fryed a board but I have had nothing wrong so far. I don't know what the dude did to this mod to fry his board all I know is he did. If you fallow the instructions as I made them then you shouldn't have any issues with this mod.


--------------Parts you need--------------
- Three 9v connectors (radio shack $5 for 5)
- Heat shrink (radio shack or just use electrical tape)
- solder iron (maybe but if your don't know how to then just skip this)


Cut the heat shrink into two 1 1/2" pieces. Slip the 1 1/2" heat shrinks on one of the connectors. wire up the the connectors like so\/ making sure that the top one has the heat shrink on it.

Solder the connections together. Slip the heat shrink over the newly solder connections. Use your soldering iron and heat up the heat shrink so it gets smaller. DONE!

The other way to do this is just twist the wires together and tape them up but this is the cheap and easy way and most of the time it will come undone.

Test this in your halo to see if you have done a good job if it works then you are good if it doesn't then redo the mod.

On another note, it has been said multiple times that the 6AA batteries in a Halo actually last longer than the 9V set-up. Just more food for thought.

[theblindchicken]

I think that the two 9v batteries would allow for an overall weight reduction, but will not last as long as the original 6AA batteries.

If you used rechargeable 9v with a higher amperage (in excess of 1000mA), this may allow for the lighter setup as well as having the batteries last for a longer period of time.

But, the larger amperage may also cause issues (such as frying your hopper's board).

I bought a mod that action village used to sell, and it works awesome. 2 9v lasted me ages...like changed batteries once a year.
