Well that was a nice day again. The first testride is done and it was definately a success. Made a lot of pictures and filmed it. You'll have to be patient for the video though, don't think I can get it done anymore tonight.
This morning I first charged up that 2nd battery, then I connected all of the cables.
Then I setup the controller to get some more power out of it.
Attached my other new toy as well. Can already tell that this produced some very nice video.
And then it was ready to go outside for the very first time.
I was able to ride it outside right away. I did already notice that I was getting less power out of the batteries than I was hoping for. But it was still a lot of fun. The whole time I was riding with a big smile. This is what's called the 'EV grin'.
It's just a shame that it's going up/down hill here. Down hill it went pretty fast but up hill it went rather slow. Especially at the end when the batteries were pretty much empty I had some moments where it wouldn't get moving at all anymore. But I could still push it, jump on it and hit the throttle. Once it got moving I was able to get up hill again. But at the beginning when the batteries were still full it was really great. Could definately feel the power of the electric motor quite good already while not really having much power available yet. Think it was about 1kW, couldn't get more out of those starter batteries. I set the controller to 25V 120A (so 3kW) but most of the time I've seen between 30-60A. Just a small pulse of 100A in the beginning. But I definately enjoyed it. Top speed I couldn't see during this test but I think down hill it was around 30 kmh, up hill 0-15 kmh. Here are some more pictures.
Handsfree, really? Was quite interesting to keep an eye on the display.
Had to wait sometimes for the voltage of the batteries to rise back up again. It was only at 20V suddenly. After a minute or so it was back up to 24V. But the batteries were already depleting anyway.
No reverse just yet so I had to do this quite often. For the next testride I will have a reverse.
But then the batteries really were empty so I needed some help getting back up.
Unfortunately the batteries have to go back into the cars, otherwise I'd play around with it for a bit every day. But it was definately a great moment again. The next testride will be with the lithium batteries once they're attached onto the frame. Will probably still take a while though.
The video will come, just still have to edit it a bit and don't really have much time tonight. It'll probably come tomorrow.
