Trolling Motor powered by lithium ion 18650's?

[sikeston34m]

I took this setup for it's first run today.

First, a watt meter was connected to the SLA batteries to get an idea of what was going on there. I was shocked.

On high, the trolling motor was pulling 27 amps, but the voltage was sagging to almost a flat 9 volts. Sheesssh......

I'm not sure if my wiring sucks or if the SLA batteries are in that bad a shape.

But then came the better results.

After being hooked up to the converter array, Running the trolling motor on high resulted in alot more power.

Todays run on the watt meter produced the following results:

12.64 voltage minimum
50.11 amp peak
633 watt peak
65,500 mah consumed for the day

The single packs of 18650's performed very well. Their voltage sets right now at:

#1 - 3.77
#2 - 3.76
#3 - 3.77
#4 - 3.76
#5 - 3.77
#6 - 3.76

Very balanced and quite powerful. The end of the day's run being just as powerful as when the pack was topped off.

My wife and I ran all over the lake today and the battery still has alot of juice left.

This pushes the boat with alot more power and top speed is much better too.
