V) vs the Sullivan Hi-tork starter (210 in-oz at 12V) or the Sullivan Dynatron
(340 in-oz at 12V or a lot more at 24V)? I am asking since my Sullivan
Hi-tork looks like it finally is done for after 20+ years of service starting
everything up to the 160DZ. I need to replace it soon.....<br>

> At the beginning of this year, I have switched to two li-po packs - 2
cell,<br>
