:? I own a Flybo 6000 - one of those Chinese-made Smart Car look-alikes that is all electric. It has a 72 volt system with 6 12-Volt deep cycle lead acid batteries and a 110 charger. On the dashboard it has a Current Meter, which appears to show the amps being drawn (ranging from 1 - 15 and then 20,30, 40 in the RED) and a Voltage meter, which appears to give the system voltage load.
Here's the problem:
with the batteries fully charged, the Voltage meter shows about 73, and I start out driving and the car works great. Then, within a few blocks, the Votage meter begins to drop to 68, 65, even 58 and then the car stops. When it stops there is a kind of thud, as if some breaker is snapping, but I'm not sure. Then I switch the master switch off, wait about a half minute, switch it back on, and the voltage meter reports 72 again, I start to drive and the process repeats itself.
I would be forever grateful for any guidance on what the problem is and how to solve it, even if that means replacing the Chinese-made controller or whatever.
