Thanks for a very much for a detailed information, I'll certainly look into that and see about reading up on timer 1 for 10bits or 16bits Pwm.

Once again thank for your input

A 25-30Amp inductor might be hard to get.
Bit silly to PWM four resistive loads, while you can switch 0, 1, 2, or 3 loads on/off and PWM the fourth one.
Discharging a battery does not require load regulation to be super fast. Relays could work.

Increasing the resolution also increases the period. 16 bits of resolution means the fasting frequency is only 244 Hz for a 16 MHz chip. I wouldn't go any higher than 10 bits.

That is why I brought up series/parallel combinations, though your idea has great merit.
