Michael,
We have developed this new regulator at Smart-Fly products and are trying to find out if there is a call for this product. The regulator is a linear regulator that is adjustable from 5.0V to 6.5V. It has dual inputs so two batteries can be connected to the unit. The inputs are isolated so failure of any kind of one battery will not affect the other battery or the regulator. It has dual regulation elements for redundancy and two outputs. It has a built in failsafe switch which negates the need for very high current switches in series with the batteries. All inputs and outputs are Deans Ultra connectors to handle the high current this regulator can require/supply. Since this is a linear regulator and power dissipation varies with input voltage and output voltage we are spec'ing it at two output voltages and an input voltage consistent with Lithium packs. With an 8.5V input and 6.0V output it will supply 17.5A continuously. For a 5.5V output it can supply 12.5A continuously. It can provide peak current in excess of 25A. We ran this regulator at 5.0V output and 8.5V input at 15A for 30 minutes. The unit is approximately 2-1/4" x 2-3/4" and weighs about 2oz. We think the regulator would retail for between $70 and $80 but that is still up in the air. We developed this to go along with our new PowerExpander which I will post about when I get some pictures. We would appreciate feedback on this product since the price to introduce it will be significant.
