Which amps is this? System load? Battery? Alternator? I'm guessing this is the system load?
Things like lights can cause quite a load. How much power do your lights take? ...do you have any? What other large loads might you have?
If it weren't for the low voltage warning that may have correlated with a current spike, I would wonder if it was a sensor problem.
What does the start of the 2nd flight look like? Does it have a high load plus spike like the first does?
What does the current look like with the engine off? How many current measurements do you have? (I have 2, one for battery charge/discharge and one on the alternator. I recall that you have a field current sensor?)
Data can be tricky and sometimes you have to look at it very carefully/closely to read it correctly. You want to look for multiple signals that confirm any theory, such as a voltage drop correlated with an increase in current. There may be a combination of a problem and mis-calibrated senors.
