Took it out for trip #3 today (in salt water this time), had 5 people in the boat, it did very well, 0 issues.
Picked up a 200 Volt / 200 Amp meter from Amazon
Amazon.com: Volt Meter/DC Digital LED Amp Volt Meter + Shunt /200V 200A /Blue: Home Improvement Which looks very promising, only issue is that it "runs" on 6-24 volts. Any body have a good idea on ho to get a 6-24 volt low power source out of a 48 volt nominal pack? Normally I'd use a 7812, but max input on those is like 36. Any and ALL cheap skate ideas are welcome, although I'm trying to avoid an extra battery.
