Correct @Ysjoelfir!
It is a Ryobi indeed. If you could check it out and offer any ideas it would be greatly appreciated!!!

@nznative, do you have an oscilloscope? If so, some measurements from the Vout terminal would be very useful.

No. It is PWM or just solid state relay. Heater regulation with linear regulator would be insanity.

I suspect that board is purely for battery protections/charging. I doubt that board does any temperature control or PWM. There doesn't appear to be a connection for a temperature sensor.

Start by searching for the part number on the IC.

Thanks @Zero999 will look into it ASAP...
