Minn Kota trolling motor

Went to Armco Park with the crew - and used a perfectly awesome Minn Kota 12Volt trolling motor attached to a 11ish ft. Jon Boat.  Made wake - we were flying at least 4 knots!!!  Had good range and had reverse.

BIG ROCK DIRT PARK - Maysville KY.

Duke at Big Rock let me charge up at the office - what a cool dude, and what an AWESOME PLACE!!!

I found some VERY VERY VERY light LIFEPO4 batteries that have internal BMS / Prismatic design.  They are 36AH and weigh 5LBS for each 12 volt battery???????
I will put them into service as soon as I can find the money.

Powered by Battery Technology - Autocross




I have installed 8x88AH C&D UPS12-310 batteries in the Triumph to replace the Powersonic 35AH ones.  I will make a couple quick-change packs for the motorcycle with those powersonics.  I believe I won Slowest time of the day at the MVSCC Points Event #5 yesterday!!! :-)  I was not that farr off of the ICE cars, however - and it was a very long course.  I had the same "slow launch" problem, and broke the tranny tailshaft mount - but improved over the 3 runs i took.  Very pleased with the way the car handled... very close to 50/50 weight.  I will pull the motor and advance the timing 12 degrees on the advice of pooey1911 (youtube) before the next event next month.

Mower Design III - lost 50 lbs

Although I was getting plenty of exercise with the 130lb 35AH mower - my back was not enjoying it.  SO, I have swapped in some 22AH batteries that weigh half as much - and I'm ready to mow!

THERE!!!! I mowed the whole lawn with the Electric mower!!!


I murdered the stock batteries that came in the 8AH 48 volt Craftsman Push mower trying to mow a half acre lawn every couple weeks by charging it with a 15 Amp charger a couple times mid-mow.  I wanted it to outperform a gas mower - so It had to go the whole distance without a fillup to do that.  So,  I took a round 1/8th inch x 21inch valve cover from Mendleson's and cut a hole in the center that the motor could poke through.  I started by drilling a hole in the center and cutting pieces of pie - then the circle after scribing it by tracing a CD spindle cover.  Then, I drilled some holes for tie-downs and layed out the 4 powersonic 12v - 35AH batteries.  Made some cables from some 4GA wire at Autozone, and wired it up.  I also added the SOC meter.  It mowed the whole lawn without stopping today!  I'll make it look pretty soon. :-)
