XB-700 Li 2010 Problems
After ordering the XB-700Li 2010 Edition from a trusted website, the bike came perfectly working and in new condition except for one key thing - The battery. After reading around this forum, I have discovered the probable source of the problem is that it has become "bloated". Likely that it was just sitting in some warehouse until it was needed for a delivery. So the batteries dropped below a certain voltage level and became unstable and shut itself down. Although when the battery is fully charged, I am able to get about a half an hour use out of it before all systems fail. Everything appears in new condition except for the battery, so am I entitled to some warranty replacement? Will I have to send it in, which would be a real pain!!! Also nearing the control box, there are two wires that have nothing to plug into, one grey and one multicolored, possible problem? I'll keep updated if I receive any answers. I was really looking forward to a really extensive use, but there seem to be no other problems so far. Any help would make me more then happy!!
Battery warranties are usually shorter than the 'main' warranty on EVs, but they do usually have one. Contact the dealer *now*.
If you can test the batteries and charger, by all means do so. A better plan, though, might be to test the charger (easy to do) and just *assume* that it's the batteries if the charger checks out, and remove them. You can then test them while out of the bike. I don't know how hard it is to remove and replace your battery pack, but I'm guessing that you will soon know how...
While you're doing preliminary tests, check terminal tightness on every battery terminal. They can get loose, which allows corrosion and resistance, which can in turn lead to enough voltage drop that the low voltage cutoff becomes active.
There are two unplugged wires in mine as well. I discovered this after I had to fix a flat tire. I was really happy that the seat lifted off so easily so I could get at the wiring. I do not charge my battery while it is in the bike. I prefer to take it out and charge it that way. You can not overcharge it because the charger shuts down. I noticed that if I keep the battery connected to the bike and charge it that way then the charger keeps cycling on and off when the charge is complete. I think this is because the controller is constantly connected to the battery even when the key is turned off. I noticed that there is one line in the schematic that is connected directly to the controller and does not appear to have any disconnect from the battery. I have had my bike for almost a year, So far the battery is ok. I get good range and speed out of the bike so far. I am really happy with the low maintenance and ease of operation. I never store the battery outside the temperature extremes might damage it. Not sure but why not be safe rather than sorry. I am sure you can find batteries for this unit other than from the Xtreme, but it is not going to be easy and would require an engineering degree and a lot of patience. It's a matter of placing them in the right order to obtain the correct current and voltage. Battery technology is improving every year. Hope you might find this useful.
