I have a tc4 with a sphere comp esc and a 4.5 motor what king of lipo how many mah and how many c is good. I have a venom pro charger
Instead of just throwing a bunch of dumb numbers and mfgs around to you...
How about MORE information on what you are racing (type of track) or if you are just bashing.
The 4.5 motor is going to most likely get the ESC very hot...you'll want to use HEAVY good strand wire on your esc, and keep it as short as possible...(Both to the battery and to the motor)
The TQ wire is probably the best available.
USE a heat sink on both the motor and speed control if possible (especially if you are bashing more than racing)
Use a SINTERED ROTOR in the motor
The "C" Rating can be important especially with the low turn motors. They pull a lot of amps, and that's where a higher "C" rated battery really shines.
The higher the "C" rating, the better the battery voltage holds its load.
Also, make sure the battery fits in your tray.
Some of the higher "C" rated packs, are also larger in size (usually taller)
There are lots of GOOD Lipos on the market.
You can shop by PRICE for your PRICE range, or by "C" Rating and mAh rating if you are looking for performance.
THUNDERPOWER has probably THE Best performance packs on the market right now, but there are lots of good choices....but it would be easier to get a good true reccomendation if people know what you are planning to do with it!~
