another newb battery question

[rdhemi]

i recently bought a mmgt and have been running the rx battery block w/ 4 duracell rechargables, it seems to be kinda lagging. After looking at the rechargables they are 1.2 volt 2650ma aa where the regular duracells are 1.5v, should or can i get rid of the battery block and solder 5 of the rechargables into a battery pack making it 6v, is this dangrous to my truck or are there any potential problems I'm not seeing as of now? thx for your time

Just buy a hump pack from traxxas or something they only run like 20 bucks i think.

You can make your own out of AA's. However, the 2/3A cells in the packs that are made for RC allow for a higher current flow. Which is good for 1/16-1/18 rigs that run off the pack. For servos and such, rechargeable AA's do just as good with the necessary current flow.

Also, you will need to run 5 cells for NiMH vs 4 cells alkaline. NiMH cells do allow for more power transfer than Alkaline cells. So you still should notice a speed/holding power improvement out of a 5 cell AA NiMH pack vs a 4 cell AA alkaline pack.

I run a homemade pack in my savage and my jato. The one in my aftershock is a typical 1400mah 2/3A cell flat pack just because it fits nice.

Now if your running more than one digital servo, you may want to stick with 2/3A type packs. But for standard servos (and one digital) they seem to get just as much power/speed out of an AA NiMH pack.
