After two CC-Lite boards ate their FET's, I started installing a PTC in series with the motors on every installation of the CC-Lite. I rescued one of the CC-Lite boards, but the other one was a goner, it cooked the PCB traces and screwed up the whole area around the driver FET's.
I've since rescued a couple more CC-Lite boards that I bought dead and revived, but I've seen enough of them cooked to know that they're way more sensitive to an overload then the full Cruise Commander. The only Cruise Commander's I've had to replace FET's on have been from obvious faults, typically a motor lead shorted to ground or a motor short. I've actually had to replace a couple of the bridge rectifiers that cooked on the full Cruise Commanders as well.
Most Mabuchi 3xx can motors draw a couple hundred milliamps free running at their rated 12V power, so anything that's drawing 1.5 amps IMO is not suitable for the Cruise Lite.
The question was asked, and I answered it with my experience with the subject board. Having installed at least twenty-five of these when they were available, I think I have a fair experience base with the product, I venture to say more than most. I know I have invoices for 30 purchases of them, and I only have a few left, so the rest are out working, or they've already been cooked.
