195mAh 4.8V (Internal) NiMh pack mod....
OK. Not that I'm fixated on these little buggers or anything, lol, but I went and installed a higher capacity pack I made.
Like LBRC, I got some 195mAh 1/3AAA NiMhs. Now, as I'm finding, 1/3AAA is more of name than a standard since these cells are a tad longer than your typical 1/3AAA's.

I had to hack (just a little bit, NOT!) the battery tray to allow this longer pack to be installed. The problem here is that you need to remove the two metal posts that hold the battery cover screws in place. Once you removed them you need to cut back the plastic a bit. See the pic below.

To say that it's a tight fit is a bit of an understatement but it DOES WORK!

Cool!
I used the metal tabs that came with the batteries to solder to the next pack. I then bent them over. I made sure I only used enough solder to main a solid join, then I removed any excess. You want to keep the overall length to a minimum, since it's gonna need space for the wires on the outter edge.
I got my 195mAh nimhs from a local mob in Aus.

You fellas should be able to find similar ones locally.
I haven't tested them yet. The batts are new so I'm giving them a few cycles on the charger first. I will test it against my other stock and let you fellas know in a day or two. We'll see...
The battery cover goes on still and sticks itself into place. I'm not really worried about not using the screws anymore. A bit of tape should do the trick.

Looks good. Seems like it may be possible to cut the top of the Battery Box for a little less weight? Either way I really can't wait now till Christmas to get mine.....even though I paid for half I am still trying.... trying to wait, ha.
Actually now that I look at it more you would have to add a screw then or keep just the screw holes humm..

meh, old news mate. you gotta hang at rippers for the micro-t info, all the in kids are anyways, lol.....
anyways, I've gotten a few runs now with this pack and I'm very happy. It's added an extra 3-4 minutes on the runtime and performs better for the life of the charge. the LOSI ones would dump quite quickly. I am running the largest pinion so that detracts from it as well in runtime.
All in all, I'm happy. Think I'll convert both my micro-T's over to this type of pack for the moment....

With the battery plate glued on the chassis remains fairly rigged. I originally planned on reforming the front battery plate edge by gluing a thin strip of plastic over the seam but haven’t done so since the epoxy I used seems to be holding up, JB weld good stuff, but not fast drying.ph2t wrote: ...I was thinking that as well, but my concern was rigidity. How's the chassis flex now mate?...
The opened up battery compartment makes it easy to try out different battery options, since it worked I went ahead and added a 5th cell to the 160 pack. For 5 cell 150 or 160 pack fans it’s not necessary to open up or cut through the whole side all you need to do is enlarge the hole you fit the plug through just enough to let the battery through too, leaving the bottom of the wall intact.
