Hi

I have been burn testing my scooter batteries today with a new burn tester that Rick Huggins made for me (thanks Rick). I believe that the resistance is supposed to be 1.5 ohms, although on my multimeter it seems to indicate 2.0, ie the reading is 02.0 when set on the 200 ohms range. Is that 2.0 or am I taking the reading wrong?

Not knowing much about electrical measurements and stuff, is resistance linear? Can I take my burn time and extrapolate a figure based on a 1.5 ohms resistor?

The burn time was about 35 minutes, taking the battery pack to 19 volts or so (bloody telephone call just at the wrong moment) whereas I am supposed to get between 40 and 50 minutes, with the correct resistors, before the pack drops to 20 volts. I know that the batteries easily last 45 minutes to an hour when actually scootering, but I think I might need to get a new battery pack and test them with this resistor to get a feel for what a good test is.

Actually, I think I have just answered my own query but what do you guys think?
