i’m trying to find a cheaper battery option for vex, i’ve looked at cheaper NiMH batteries for RC cars. however, i am unsure what charger i should get inorder to match the vex power pack, or whatever battery i am using
unfortunately i doubt you’ll be able to find a suitable replacement for the vex batteries, at least not for a significant amount cheaper
remember, if you do find one it is very important to make sure it meets and does not exceed the current and voltage requirements
i suggest searching the following sites:
www.jameco.com
www.robotshop.ca
www.hvwtech.com

hope i helped! :D](www.sparkfun.com)
I agree. If you do find a cheaper set of (quality) batteries, please post back here with details.
You might want to read this thread started by stampede_dude. He did some analysis and found the Vex batteries to be higher quality than most, so they may be a better value than they appear based on price alone.
Here are a few options from Radio Shack for you to look at:
[LIST]
*]Transmitter battery & charger (9.6V, 1000mAH, NiCd, $16) 23-342
*]Transmitter battery & charger (9.6V, 1600mAH, NiMH, $20) 23-432
*]Robot battery & charger (7.2V, 2000mAH, NiCd, $20) 23-322
*]Robot battery (no charger) (7.2V, 3300mAH, NiMH, $25) 23-319
[/LIST]
I’ve used the first one on the list and it works just fine. The other ones look like they should work with Vex and seem like reasonable values.

thanks fro teh help, i think i’ll stop by my local radio shack for the 2 batteries, and hopefully save some money
Alternatively you can also assemble your own batt pack. For the vex microcontroller you can use 6 to 8 cells (Well the vex pack is 6 cells but 8 works too). Used to have some 10Ah D sized cells lying around…
I’m not sure I would use homemade battery packs, that sounds like a recipe for disaster…
yea never ever solder batteries
i’ve tried, its a recipe for disaster
