After a bit of frustration with the charger, two broken drill bits, and sore fingers from hand tightening bolts, my car is at last on the road again. Just in time for the SLO Mini Maker Faire as well which should provide a nice opportunity to show what I've done. If you're in the area, stop by!
Here you can see one of the battery packs under the car bolted in (that's what the drilling was for). There's a lot more ground clearance than with the lead batteries; almost 6 inches at the lowest point. This made for a pleasant surprise when I pulled into a parking lot and saw a speed bump. I inched towards it expecting to hear the familiar scrape of the steel case of the lead battery pack, but instead just went right over top with a grin. While this may not seem that exciting, it's been a long time coming, and I'm sure my local stores will appreciate the lack of further chunks missing from their speed bumps. I'll update with more pictures once I get the chance to clean up the car and the wiring under the hood.
The BMS performed quite well on its maiden voyage and showed a 90% charge remaining after the slightly more than 5 miles of driving I did today, which is great news considering how excited I was to see how the car would perform with so much less weight. All the cells seem to be well balanced with the exception of one that seems to be dipping a little bit more under load. This may be due to a loose connection so I'll need to take a look at that. Overall I'm very happy with the system.
Until next time.
