FEELER POLL - Dilda "Hop-Up Kit"

I have a buddy working on machining an extension tube to allow the use of (3) cr2's in the standard Dilda, but still have no idea what they would cost in quantity, hence the feeler ... My goal would be to sell a complete kit with (3) 3.6v CR2 rechargeables and the extension tube so you could turn your Dilda into a 10+ Volt MONSTER easily and conveniently (at your own risk, of course) - if he comes up with some ridiculous number like $25 just for the extensions then screw it, but if they could be done low-cost, and people were interested, I could probably be shipping the kits within a week or so.

Hey Dale, what would all be included in the 'KIT' ? If the price is right, put me down for one, OK ? Thanks buddy. rob

The goal at this point would be to bundle (3) 3.6v rechargeable CR2 batteries and the extension tube so basically you would unscrew the tail, screw on the extension and insert the 3 batteries, then screw the tailcap back on and done deal - 10.8v Dilda! I'll keep you posted on the progress with the extensions (my buddy said he should have the first prototype done either tonight or tomorrow and then we'll figure out the cost, etc if it works as planned).

Bit of a one sided poll isn't it? What about outside the US?

Oops - didn't mean to exclude anyone, I just haven't done the research to know what the additional shipping would be ( the price difference would only reflect the actual extra cost).

Hey BCM...
   did you do any testing of the dilda with 3- 3.6V CR2s... :-?
If so... what was the "ON"/"OFF" timming (duty cycle)...

I've done a small test at regulated 12Volts input to the Dilda Driver and it (the driver and LD)
gets extremely hot real fast.. and 3- 3.6V fully charged CR2s IIRC will be at 3 X 4.2V=12.6V...
Not trying to shot you down... even knowing all this... I'd even get one of your extensions
myself..
Users might be a little safer with 3- 3.0V CR2s.... :

Jerry - until I get the extension prototype I haven't run the (3) 3.6v Juice in the Dilda, however I just took a minute to check the 6 batteries I have (all fully charged) and hmmm, looks like you might have saved me some trouble here, all 6 are at 4.13 or above (3 of them are above 4.3) ...

Hmmm, (3) 3v CR2's output at 9v (with extension), or (2) 4.3v CR2's output at 8.6v (as is) ... Kinda makes the whole thing not as spectacular, even with (2) at 4.13 thats still 8.3v so gaining less than a volt with the extension doesn't look so great.

Oh well, the prototype is on it's way so I'll do some testing with it in different configs and post the results anyhow, maybe theres still life left to this project!

We're a curious bunch.... so just keep us informed..

You say that 3.7 volt lithium batteries are 4.2 volts maximum, but don't mention how 3.0 volt lithium batteries are about 3.5 volts maximum. :-? :

I think you're right, Jerry, this will cook the driver board, and possibly overvoltage the 6V tantalum at the same time - but if the linear driver board were replaced by a Boost converter, it would give longer run times and less heat.
