SR20 pilot reported electrical system failure during flight. Pilot diverted to appropriate airport.

Narrative

I flew from ZZZ1 to ZZZ; during my climbout from ZZZ to ZZZ2 (about 10NM away from ZZZ)i had an Alternator 1 failure. I ran the QRH; shut down the AC and landing lights and set direct course back to ZZZ1 because the alternator 2 was working and the battery didn´t get drained (-0). Did a precautionary climb to 7500ft in case of upcoming engine problems. After 5 min at cruising altitude alternator 2 failed. M Bus 1 and 2 caution message. Battery got drained by -24. Checked my position and calculated the remaining time to ZZZ1; that was more than 30 min. Checked nearest airports and set direkt course to ZZZ2 (24NM away). Did a landing with lights off and flaps up to save battery charge;Alt 1 failure during climbout from ZZZ to ZZZ2; did the QRH Items; Alt 1 failure remained; no battery discharge so direct course to ZZZ. Precautionary climb to 7500ft; 24NM past ZZZ2 Alt 2 failure; M Bus 1 and 2 caution; Battery discharge at -24; direct course and landing at ZZZ2. Landing without lights and flaps to safe battery charge.
