Yes it says Batt 7.2 V on the PCB

Thanks for your reply. The car is this one https://www.matcotools.com/catalog/product/MTCRCCAR2/AMPHIBIOUS-RC-CAR/ It is indeed a basic toy RC which I'd like to experiment on and definitely not worth spending lots of money on. Your guess is correct, it is a combined receiver and ESC. Car takes 9 AA batteries (1.5V), no clue about the motor. I would avoid messing with the motor if possible as it seems to me it might be expensive and more complicated than what I can handle but perhaps it's worth looking into. I was hoping to fiddle around with voltage/battery/electronics to get some more oomph out of it as it's quite slow while sucking a lot of battery.

Many thanks for the prompt reply! I'll definitely look into the third option, it sounds like something I could handle (I'm still a beginner in the RC world but like to expriment with stuff). The crawler is this one https://www.matcotools.com/catalog/product/MTCRCCAR2/AMPHIBIOUS-RC-CAR/ It's just a basic, entry level RC that I bought for my son (who's 5 years old), but I'd like to pimp it up a bit... Now I should find out what battery pack this thing can handle but no idea where to start from. It takes 9 AA batteries (1.5V).

Hello everyone. I'm looking for advice on how to upgrade an RC, I hope this is the right place to ask: I would like to to make it go faster, however I don't know much about pcbs and batteries (but I definitely know how to handle my soldering iron lol). I've attached a couple of photos of the crawlers' inside for your reference. I'm guessing I should buy a more powerful battery pack (not sure about voltage etc.) to go with a new pcb that can handle more voltage perhaps? If anyone could point me in the right direction that would be much appreciated. Many thanks
