...your battery pic was a very low mah meaning run time...
A 3s 3300mah battery is almost an exact equivalent to a 2s 5000mah battery (actually you'd need 3333mah
). Feed them both to the same watt motors spinning at the same RPM and they'll run for the same length of time (actually the 3s would run a bit cooler, a bit longer). You can't look at mah and ignore voltage when comparing the work batteries can do.
For someone that just bought a stock Caldera, that battery is an extremelypoor recommendation
- Yes, it supports 5c charging.. but it would need 32.5a at 8.4v (full lipo, 5c x 6.5a)... or 22.75 amps required from the 12-volt power supply. None of the chargers on KCHobbies even go above 10a, nevermind 20 (most chargers do about 6a). Don't pay more for a battery that can be charged faster than your charger can put out the juice!
- A150c discharge rate is impressive! That means it could deliver 6.5a x 150c = 975 amps! But the ESC that comes with the Caldera
is rated at 35a, peaking at 190a. That means at a sustained 20% of what the battery could deliver the ESC would let out the magic smoke. Don't pay more for a battery that can put out more current than your ESC or motor can use!
Assuming a standard 5000mah 2s lipo, you'd never need more than a 38C pack (round it to 40C: 190a / 5000mah). Didn't I recommend 45C batteries?
The 2s Turnigy Nano Tech battery I linked will only give about 77% of the runtime of the KCHobbies one (5000mah vs 6500mah), but it only costs 23% of the price ($32.63 vs. $139.99), and the car will have the same amount of "punch" with each (both limited by the stock ESC and motor to a 190a draw). And because the Turnigy is smaller, it's also lighter (279g vs 354g) - so the Caldera will accelerate faster, and handle better.If runtime is the problem, buy a higher mah Turnigy, but for the love of [insert diety of choice], don't buy that $140 battery!
