This forum was very helpful as I started a go kart project about a year ago. I can not express how greatful I am for the free advice. I became so fascinated with electric Go Karts that I actually started a business. VenomKarts.com. For safety reasons, we are going with 48 volts and Nissan...

I recently finished a project during which I upgraded the motor and charge controller on a Razor Ground Force Drifter. Specifically, I added a 48v 1,000W motor and charge controller to the go kart and powered it with a 14S9P 18650 battery pack. As you can see from the picture below, I soldered...

So after a cold night of sleeping in a camping tent I thought I might bring an electric blanket powered by a 24 V lithium ion battery pack next time. What would be a good inverter to use with this type of set up? The electric blanket would be a standard 110 V electric blanket. Thanks for any...

I am embarrassed to ask this question but here it goes .... If I install the following shunt (with voltage meter) on my electric go kart, do I simply bolt the shunt directly onto the metal frame or does it need to be bolted to something nonconductive (or a wooden mounting base on the go kart)...

I am about to build a 18650 battery pack for my electric go kart project and I wanted to make sure I had a sufficient number of nickel strips for the current that will soon be flowing through the system. Here is the setup: 48V 1000 Watt Brushless Motor with rated current of 26.7 amps 48V...

After reading many discussion threads, I am convinced that a fuse is a necessity. Since a fuse is a low cost safety feature for any project:huh:, why would anyone not use one? Are there any disadvantages?

Hello everyone. This is my first post and I really appreciate all the great information from the experts on this forum. I am currently modifying a Drifter go kart (see 1st photo) by replacing the existing 24 V lead acid (14 amp hour) battery with a home made 24 V (7 series 2 parallel) 18650...
