Newest production run arrived a few weeks ago -- we changed the output FETs to the same parts the newest 3500Ds are using (more powerful) and made a few other small tweaks.

0.5 ohm performance is now just as good as the v.1 1500D while maintaining the slightly better 1 ohm performance that we had already achieved on the v.2 model.

I don't have any 1500D v.1s around the shop right now so I'm using previously tested data :

1500D v.1

POWER : 1970 Watts

AMP VOLTAGE (measured) : 49.25 V

AMP CURRENT (calculated) : 40 A

ACTUAL IMPEDANCE (calculated) : 1.23 ohms

SUPPLY VOLTAGE : 12.85 V

1500D v.2

POWER : 2030 Watts

AMP VOLTAGE (measured) : 47.4v V

AMP CURRENT (calculated) : 42.8 A

ACTUAL IMPEDANCE (calculated) : 1.11 ohms

SUPPLY VOLTAGE : 13.3 V

So essentially identical performance within margin of error now on 0.5 ohm operation -- which is great since the v.2 is 1.6" shorter than the v.1 model was !

I'll have to get some 16v testing done too -- but I may wait until I actually have a v.1 model 1500D around to do it head to head. I'm sure I'll get one traded in again eventually.

Holy !

The V.1 was such a Tank and now to see the V.2 exceed the V.1 is amazing considering the new smaller footprint!
