Is there a limit to how many battery extenders you can use???
Are you talking about the extension cable or the power expander? You can only have one power expander (You know, the thing that lets you have two batteries) but you can have any amount of extension cables to my knowledge.
ok i needed to know about the extension cables.
There’s no limit
If you’re talking about the Battery Extension Cable, then you are allowed infinite (although I would never see why you would need more than 2), but if you’re talking about the VEX Power Expander, then you are only allowed one
