 That will limit your current to less than 2 Amps,
assuming that you are getting about 20 VDC unloaded
and the output drops to about 12 Volts at the current
limit. If you are getting less than 15 VDC, the
current would be limited to less than 200 mA {at} 11 V.

 Personally, I'd use a fuse of the appropriate value
when using the unit as a power supply (ie 2A fuse for
a limit of 2 Amps, 3A fuse for a limit of 3 Amps, etc)
and I'd use a light bulb to limit current when using
the unit as a battery charger (ie 25 Watt bulb for
2 Amperes, 35 Watt for 3 Amps, etc.).

 Also, I'd measure the unloaded output voltage. I'm
afraid that it will be too high to be safe as a
power supply. Many parts have a maximum rating of
15 or 16 VDC. Running them at the maximum is very
dangerous.
