My scooter is unfortunately back in the shop to have a cell in my battery pack replaced. Seems that the voltage must not have balanced with the other cells and that led to failure of the cell. This is the risk of not using a full BMS system and using a more primitive balancing solution instead.
The new cell is replaced and I will be picking up my Z6000 from Electric Motorsport tomorrow. This time I’ll be hyper-vigilant in checking the cell voltages and will baby the scooter for a while till things look good.
By now most of us have heard about how the “Fiscal Cliff” was addressed in a new tax deal that raises some taxes and maintains some previous incentives.
The big news is that the minimum requirement is a 2.5kw battery back down from 4kw which makes this available to many more buyers. The incentive is 10% of cost up to a max of $2,500.
Unfortunately, the Electric Motorsports Native Z6000 falls a bit short of that. Finding a way to squeeze 60ah cells into its compact body would solve that problem and give an almost 50% range boost as well. The bigger capacity cells are similar in size but 4 inches taller which presents a big challenge. But the extra cost would be negligible after the rebate!

I’ve now been driving my Z6000 for over two years. It’s still a great way to get around town but has had its share of problems. One brake fluid reservoir corroded and had to be replaced. I’ve had one tire replaced — the stock tires are sticky which results in great performance and not so great tread life.
I also had the seat replaced which wasn’t expensive but really didn’t last long in part because it was parked outside for extended periods. Some of the plastic cracked when they were servicing it and they replaced it (EMS) without charging me for what was quite a bit of labor.
In summary, I like the scooter but it’s been a bit of a headache to keep up with the issues that have arisen.
Today I rode for the first time after reprogramming the controller in my scooter. I had lowered the maximum power from 80% to 70% and reduced the maximum speed as well. Making the change was relatively easy once I properly configured my windows xp installation running on Parallels on my Macbook Pro. The application itself was a free download.
Most important, was testing the range, the issue which has been most difficult for me. I’ve previously attempted a 16 mile round trip only to complete the last couple of miles in “limp mode” when the maximum speed is only a few miles an hour. This time I fared much better, riding 22 miles before I limped the last few feet home. Twenty miles is enough for pretty much any ride I would undertake without having the opportunity to charge in the middle. i can now easily visit friends in Alameda without a problem, though the furthest points of Richmond might be pushing my luck, especially if steep hills are involved. For those who may be reading this and who are located in a less hilly region than Northern California, note that I had some serious hill climbing in these 22 miles. The most noteworthy was the steep climb up Pleasant Valley Road from Broadway up to Piedmont Avenue. In a less hilly region, it might be possible to squeeze a few extra miles. When time allows, I may try a flatter ride to see what difference it makes. In the meantime I’m grateful to have the extra range.
But how much did I give up in terms of power? My maximum speed at 80% power was 50mph which I only hit a couple of times. 45mph was a more realistic max. Now that has been reduced by 10mph to just 35. Fast enough to maintain the legal urban speed limit, but occasionally a bit slow to keep up with traffic. It’s a compromise for sure and I can always tweak the power setting a bit to 73 or 75% if I decide its necessary.
