Voltage and current question

[tc3_racer_001]

yes that makes sense. theres no point in balancing when they are less than 75% full. the cells will usually sort themselves out near the end, but i just plug them in and let the charger do its own thing :)

<> as long as you don't have your voltage so high that you are revving into your motors inefficiency rpm range, the following statement is almost always true. In a truck with two available setups, if it's geared to go the same speed with each setup, the higher voltage setup will draw less current.

I agree fully with the lower kv motor option. A much better solution than just gearing down a motor spinning way faster than it needs too. No need to spin the motor much more than 30K rpm in my opinion.

Adding voltage and just gearing down to attain the same top speed can help a little if you are having ESC temp problems, but really wont do anything for you as far a motor temp problems in my experience. It may actually cause motor temp problems from what I have seen.

Getting a motor of the proper kv range for the voltage you plan to run is by far the best solution.

Higher voltage, lower motor kv, and similar gearing will product the best results for lowering current (amp) draw.
