17/18A is a little on the low side. You want about 25% more current capability than you will be running for two reasons: 1) heats less 2) the output voltage won't drop as much and will stay within the 11-15v range of most chargers.
The 0610 is a 250w charger IIRC. To use it to full capacity, it would require:
Code:
Voltage Min A Safe A
11.0V 28.4A 35.5A
11.5V 27.2A 34.0A
12.0V 26.0A 32.6A
12.5V 25.0A 31.3A
13.0V 24.0A 30.0A
13.5V 23.1A 28.9A
14.0V 22.3A 27.9A
14.5V 21.6A 26.9A
15.0V 20.8A 26.0A
The "Min A" column includes an 80% charger efficiency factor.
