Hi Ryan,
I guess it depends on some factors. If its a lithium battery then it will have a BMS and it will probably have an overcurrent cutoff set somewhere above the 60A maximum, sortof like a digital fuse, it might be set to 75A or something like that. In theory if you have 4 together then they can support a combined 4X higher levels of current to the motor, but in practice you might have problems where one of the batteries is putting out more than its share of the current load and then the BMS for that battery goes into protection mode. If you have thick cables uniformly sized in the parallel bank that could help balance the load. If you are able to tweak the BMS settings then you should be able to make it work, for example the initial starting current might throw off one or more of the batteries into protection mode but if you can re-configure the BMS to delay the timing of that overcurrent cutoff from say 20milliseconds to 1s or something then you might be able to eliminate some initial starting current issues.
send a link to the battery I am curious to see it. 60A output on a 200Ah battery is a really low C rate. What it the battery chemistry?

I'm looking at battery options and I see a 48v 200ah battery with a max discharge of 60a. If 4 of this this battery is in 4p, at 800ah, will that also allow for increased max draw to the motor or will it still be 60a?
