Lawrence,
Thanks for writing and sorry about the trouble that you're having.
Firstly, if you got the kit from Ryan at Underscore Electric Vehicles, it would be best to visit him and let him have a look at the kit - when you get a kit from a bike shop, they're your first answer for technical help and support, since they can look at the kit and see what's going on, while we can only diagnose over the phone or email.
Second, you may be experiencing normal operation. We rate that 10ah battery for 12-26 miles of range on a bike kit or 10-24 miles of range on a trike. A heavy bike, minimal pedaling, operating at high speeds, headwinds, hills, carrying extra weight, or frequent starting/stopping or acceleration can all limit your range by burning up power faster than average. It's also not uncommon to see the battery meter at "full" almost all the time with this kind of battery - a Lithium battery has a high voltage and mantains that voltage until it is out of energy, so the battery meter is not accurate like with a sealed lead acid battery that has a consistent gradual voltage drop. Also, a fully discharged battery can "recover" over time when the voltage rises after it "rests" with no load, then you can turn it back on for a short time.
With these three things in mind - that your distance of 9 or 10 miles is very close to the rated range, and that the battery meter will appear full until the battery is empty, and that a battery can recover after sitting idle, it seems like a possible explanation is that the battery was used up as normal, shut the kit off, and after a while recovered enough to run again.
Please let us know how things go with Ryan and if he is able to help you dig a little deeper and find any potential problems with the kit.
Best regards,
Alec

Comments: I just got my E-BIKEKIT™ 48V10AH LIFEPO4 LITHIUM ELECTRIC BIKE BATTERY Monday. I'm using your discontinued front direct drive brush-less hub kit that I purchased about a week before you discontinued it. I bought all of this through your seller Ryan Cross. Yesterday on my first test ride with the new battery I only got about 10 miles and it completely died. I had it plugged in overnight so it was fully charged before I used it. I was pedaling most of the time. At about 9 miles it dropped a bar and at another quarter it went to three bars, then to one bar, then to zero and died. When I got home I turned everything off and then back on and it went to 4 bars and started working. I've got the monitor set at 48V, 26", and #46. When I was running it at 36V it was showing a top speed of about 24.5 mph. I know it's going faster at 48V but the monitor is registering about half the speed I'm actually going. I'm thinking it has to be the controller, monitor or maybe both. Are those still under warranty?

Okay, that's fine as far as the range on the battery is concerned but I'm still having the problems with the controller and LCD monitor that I mentioned. If I can, I'd like the monitor and controller replaced under warranty. If you send me a return shipping label, I'll send the old ones back. Thanks.
Ryan doesn't have any extra ones in stock as far as I know.

to me
Lawrence,
Yes, if you would like to send the controller, wiring, and LCD to us, when we receive them we will test them here and troubleshoot any problems, repair or replace parts that are covered under warranty.
Your speed will be determined by a number of factors, like terrain, total weight on the bike, bike type, tire and wheel size, but a 10x6 (small 10mm 9-pin plug) direct-drive motor will have about a 18mph top speed at 48 volts with a 26” wheel, while a 6x9 (large 14mm 3-pin plug) motor will have about a 21 mph top speed with a 26” wheel
It sounds like things are set up in your LCD correctly, if you have a direct-drive motor and 26” wheel, but I can’t double check since your order is through underscore EV. Again, you might want to double check with Ryan to be sure that you have a direct-drive motor, and which type it is.
It may also be worth checking your battery charger to be sure it is the right type – it should say 57.6 volts 3amps on it. If you have a 36 volt charger (it will say 43.2 volts 3 amps) then your battery could be slightly under-charged, effecting top speed and range. I don’t think this is likely, but just to cover all our bases.
Best regards,
Alec

I don't need to check with Ryan on the motor type. I've been riding, working on, and building ebikes since 2009. It's a brushless 36-48V DD hub kit made for a 300lb plus weight. The charger is the silver colored 57.6V 3A version. On your site when the kit was originally purchased the rated top speed at 36V was close to 20 mph and at 48V was 30 mph.
If I were to send you the controller and monitor before I get new ones, then what am I supposed to use for transportation in the meantime. I don't drive. I don't have a regular front wheel for my bike.
Last time I had one of your sla chargers and it blew up on me you guys replaced it no problem but now when I have any other warranty issues it seems you're trying to do everything you can to avoid honoring the warranty.
