My Lashout Cuts Out!
I recently purchased a Lashout electric bike used on craigslist. It has a standard 24 volt SLA battery setup and has a 600 watt motor (I think). It's about 3 - 4 years old, but does not appear to be abused and is in good cosmetic shape. I live in some pretty good hills near San Francisco. The block in front of my house is a 10% grade. The first time I took it out I was able to get up the hill with a lot of pedaling. After that I took it into some nice rolling up & down hills - nothing too bad, but after some coasting and some pedaling it started to cut out. I could always get it running again by turning the power switch off for a few seconds and then it would run again. It cut out 5 or 6 times. I felt the motor and controller area but they were not very warm at all.
I figured that it was due for some fresh batteries as the ones it came with would not charge up past 13 volts each. I took the Battery Pack apart to assess the condition of the batteries after charging; Left Battery = 12.82, Right Battery = 12.99 volts.
So I ordered new B&B 12volt 12 amp replacement batteries. After installing and charging the new ones up, the voltage now is about 28volts combined. Today I took it for another test spin around the same area. This time it still cut out, but not as much – maybe twice instead of six times. Again I felt the motor and controller area but they were not very warm, certainly not hot. An improvement for sure, but is this the best I can expect?
Any ideas as to what the cause is of this cutting out problems? Is this normal for this bike? Is the controller weak or underpowered? I weigh about 230 lbs. so that might factor in. I need to know, as I might consider just replacing the entire motor with a Phoenix Cruiser or Brute, but not if it’s not called for. Any suggestions will be appreciated!
