Not sure I understand this suggestion as the ESCs are cheaper than that on HW's website. $39/$47 respectively. Am I missing something here?While i mostly agree with this, i would go a slightly different route. Look for a Redcat Racing rebranded HobbyWing ESC. They are listed on eBay as the WP 10BL60-RTR ($45 or less) and WP 10BL120-RTR (around $58).
8.36 is the voltage of both cells together. Maybe I couldnt see the orders of the wires correctly. a 2S lipo has a max voltage of 4.2volts/cell or 8.4V for a 2S pack. So that lipo is pretty much fully charged. If you play around with your multimeter on the balance plug 2 of the readings will be 4.x V/C and one is going to be both cells together which is the 8.x V/C. You dont want to discharge lipos down past 3.2V/C. ESCs will have whats called an LVC (low voltage cut off) you can set to make the car stop running when the bettery reaches a certain level of discharge so you know its time to charge the battery. This keeps the lipo from getting damaged.View attachment 135333
@Greywolf74 i have the correct charger that came with the car, basically have everything it came with here. The battery voltages are;
Red/black 8.36v
Blue/Black 4.16v
I guess that’s a problem?
Also the battery is in a plastic bonded case, it MAY be very very slightly pushed out at the centre but that could be how it came for all I know as it’s so slight I could be just imagining it! Is it worth popping open? Or is that a bit dodgy lol
In order to tell if theres any slight puffing lay the lipo on a flat surface and see if its flat or if it can rock side to side. If it can rock side to side its puffed and should be safely disposed of.
It is a cheap RC and will cost a minimum of the ESC and receiver to get running. That being said the state of the motor and the servo are still unknown also unless you have a servo tester? Motor is probably fine but if Bigman was right about the motor being hard on ESCs then Id get the 120A ESC. Its only a few bucks more.I get the feeling this may not be worth the money it will take to fix it, if it needs new battery, esc and receiver especially when I’m trying to sort the two nitro cars I have already haha starting to see how this hobby gets expensive lol
Up to you whether you want to put the money in to fixing it or not. Its true that its a cheap RC but in teh overall scheme of things it wont be that much to get it up and running again and it will at least have a better ESC in it. Even if you bought a HW ESC and motor combo, receiver, and a cheap servo in it you'll liekly be less than $125USD in it and it will technically be better than it was when it was new. At least from an electronics stand point. Could be a good learning experience but then again you might just want to put that money toward a proper hobby grade rig too. That is totally up to you mate!
I would not count the cost of a new lipo battery toward what it will cost to repair this rig as the lipos can be used in any RC and, to me at least, is a cost in and of itself. At least if you plan on owning more electric in the future.
