Gavin Scooter User’s Manual and FAQ (
George Irvine 2002)
How To
:
The goal is to test how long your batteries will burn without doing it on the scooter.
Short burn times indicate bad batteries. (Trust me...)
The circuit above represents the load of the scooter.
1. Wire the circuit. The resistance at E should be
1.5
Ohms.
(If it is higher you either have not "zeroed" your meter or you have not done a good job
soldering the wiring to the resistors.)
2. Charge up the batteries.
3. Reset your stopwatch.
4. Hook up the load and start your watch. The resistors will get
HOT
!
5. Measure the voltage while under load. When the batteries hit 20 volts under load you
are done.
A short tube Gavin should burn about
50
minutes.
A long tube Gavin should burn about
95 to 100
minutes.
Ask George if you have questions.
