Max amp draw
What is a max amp draw for a pair of Trojan T105s? I am trying to figure out wire sizing.
Forum Discussion
For the AGM version, the Trojan data sheet shows the short circuit current as 3250A. They don't give this specification for the flooded version. In general, a flooded battery would have a higher internal resistance, and so a lower short circuit current, but I'd guess it's still in the range of thousands of amps.
The proper approach, as others have mentioned, is to size the wires for the maximum current you expect to see based on the connected load or charging circuits, and then provide appropriate overcurrent protection (a fuse or circuit breaker) sized based on the wiring. It is utterly impractical to size the wiring for the maximum current the battery can provide...except perhaps in a situation where you actually need that much current, say for a battery testing and characterization rig.
