My daughter has a Ecosmart scooter. She's 15, 120 pounds, and needs it to drive to dog sitting gigs in our neighborhood. We live in Missouri where it can get pretty cold in the winter. We are using the original batteries (which we've had for two years. The scooter stays in the garage in the winter. Last winter I bought a heating pad and kept it plugged in on top of the deck all winter).
1) The current batteries conk out pretty quickly. We live in a very hilly area. So the scooter is either struggling up a hill or coasting down. There's not a lot of flat area. So currently if she goes about 1 - 1.5 miles one way she cannot get the scooter reliably back home. I want to replace the batteries with ones that will a) reliably get her to and from about a two mile away destination, and b) still be good when we likely sell it in a year or so (as she will be driving a car at that point), and 3) require no modification other than new batteries. I don't think I need the 36v upgrade I've read in the forums. So my question is whether I can just upgrade to the 12v 9ah (UB12100-S) batteries and keep everything else the same (i.e., same charger and harness - I know I'll need new spade connectors)? Will the 9ah give her any more range? Again, I think our biggest struggle is hills. And we just need it to really wrk well for one more year.
2) Is the battery loss she has a result of the cold winters? She really doesn't use it that often (2x/week) and we keep it plugged in at all times. Has the winter or the constant plug-in damaged the batteries? And is my solution of the heating pad sufficient to ward off damage for these new batteries? We don't really have a good place for her to keep it in the house. So I'd like it to live in the garage. Plus it's really heavy and not easy for her to get over steps.
Thanks for any advice.
If the heating pad is used in a way that prevents the batteries from freezing then it will prevent them from being damaged during freezing weather. Another method to save the batteries from freeze damage during the winter would be to remove them from the scooter and bring them inside the house. However, the battery pack should be placed back in the scooter and recharged every 30 days so this may not be very convenient depending on how many months the freezing weather lasts for. To make this more convenient we sell an off-scooter charging adapter for the battery pack which will allow it to be recharged when it is out of the scooter.
Please let us know if we missed any questions or if you have any further questions.
Can you please provide a link to one with the wiring harness soldered? I only saw that one wiring harness was needed. So would I buy one with a wiring harness and two without?
You're very helpful. Thank you!
Regarding your question about buying one with a wiring harness and two without. Could you please rephrase that? I'm not sure I understand what you mean.
