The 2016 BORG II ?

Shucks just when I thought I was done with the first generation the issue of optional heat sinking for the Bi Polar NPNs came up. Yeah it's done. Yeah it ouput 83-amps into a 12.17 load. Relays, timers, eveeything looks good but now common sense tells me to really pay attention to the BTU issue. I tried that heat sink site link but the request a quote freezes. Going for 27500 8" in length qty (4). Arctic Silver slowest cure silver epoxy on outside, silver heat sink compound under the bipolars.
