Oh.. treble that - apparently 45A - 200A is the range...

But not charge current into the battery.
Yes, charge current into the battery if its flat enough


A quick look at a few battery specs suggests that a charge rate above
50A can damage a lead acid battery if maintained for more than a few
minutes.

Most battery manufacturers suggest a charging current at C should be
considered a maximum, so an arbitrary 50A doesn't cover many battery specs.

YMMV
