Big batteries need a big load

A project log for Electric Snowblower Conversion

Using a 1979 Ariens chassis, but replacing the small engine with a DC motor

I was using my battery tester to discharge these batteries but it was taking far too long.

So I took some 22AWG 316 stainless steel wire, and made my own heater. Since it's so cold here in North Dakota I figured why not? With the boost converter inline, I pulled over 30A from these batteries for a few seconds, no problem.

Also, here's a teaser photo of the contactor, more on that next time.
