I see 12V alternators up to 300 amps for sale. What happens if the battery is run low and the boat takes off at full throttle? Does the battery really get hundreds of amps thrown at it? Traditional high amp battery chargers have 40 amps as the cut off with bursts of 60-100 amps for starting. What's the most amperage an M-30 AGM battery will accept when drawn down? Does it get to even 50 amps before the voltage hits 14.3 and backs off the regulator?
