So the past few days I have FINALLY had time to take my Klima our to some beautiful nature parks and put it through it's paces. I finally got fully geared up and hit the pavement, and DAMN was that completely freaking exhilarating!! BUT, I must say, if I could rewind time there is absolutely no way I wouldn't spring the extra cash for the Klima Max! I'm kicking myself a little bit, but at max speed and weighing 192 lbs/ 87kg, with the throttle largely open I got a little more than one hour of fun before my voltage sag showed 16% (I started out at 75%, trying to observe the 80-20 rule). When I let the scooter rest it settled at 25%, which is ok, but man I was suprised how fast that could run out.
I would urge anyone who's already springing for the Klima to please, please do yourself a favor and consider the max! Originally my scooter budget was $1400. The Nami was an insane financial stretch for me already. However, knowing what I know now, I would EASILY spring for the larger battery, no question.
This leads me to a few questions and statements:
- How bad is it to run the battery outside of 20-80%? In other words, if once a week I want to take her out and open her up, can I occasionally charge to 100% before the trip (with a grace period between charging/riding) and ride it down to 10%? What if (after 30/40 minutes I get her home and plug her in? Is the damage done simply by going so low, or by the amount of time it stays low? This is important to me because it will dictate/limit what i do as I don't want to create unnecessary damage.
- Is there a battery upgrade path? If so, what are the specs we need to be considering when looking for an upgraded battery, and just how big of a battery can one get before there starts being a spec mismatch? In other words I would still like to stay within the tolerances that have the controller/motor receiving a normal-ish level of input/throughput. What's the price range of these batteries purchased either directly, or through third parties over ali, etc.?
- I think that in the future more scooters should feature easily managed removable batteries, ones that can be swapped seamlessly and quickly, so that (if finances were no object) I can have two extra batteries on me at any given time. I don't expect them to necessarily be lite enough for transport on the scooter itself, but at work, at home, in the vehicle while on the road, etc., I could carry spare batteries. The other point about removable batteries is scooters could be more reasonably left in the car for a couple hours. If the battery is the only component that is so sensitive to heat fluctuations, if one could remove the battery I think a scooter could feasibly be stored for several hours in a car without too much concern, or am I missing something else about this? SPLACH just featured a removable battery in their new M8 release (not making a comment on Splach, it's too soon to make a judgement call there, not enough data..).
- Battery technology must, and will, continue to evolve. This weekend at a car festival in Detroit (The Woodward Dream Cruise - Woodward is the original drag strip in the home of the automobile) several biker dudes took an interest in my Klima and were picking my brain about it. They were really excited about the electric future, but when one guy asked me about the current range and I said "roughly 30 miles or so, depending on your weight" he smiled at me and said "ahhh, thirty miles? That's when you're just starting to have fun!" and it hit me just how right he is! And just how prescient it is that we have gas stations literally all over EVERYWHERE! What will be the battery equivalent of this? The infrastructure needed will be massive! But ranges keep increasing and the financial incentives on battery manufacturers to evolve are MASSIVE! I just can't wait to see what's next... lithium air? What else is out there? Anyways, once we can do 100-150 miles we'll really be getting somewhere! For now I know that, if I'm going to go out full throttle for some fun, that will be about an hour or so of fun. lol
