Did I fry my batteries?

[drakester]

Morning everyone! Have really enjoyed this forum and have had our 2021 2 seater since nov 21…about 1,100 miles. Recently went on 2 week vacation and thought I’d turned off main switch but I must have not as came back and cart was totally dead. Might have made a critical mistake as I just hooked up charger overnight. Came out in morning and garage smelled like rotten eggs and charger was still in red and batteries sounded boiling.

Now the cart amps when fully charge drop to about 44 on standing flat start and into low 40’s on hills with speed still at 25mph. Did I fry the batteries and need all 6 new in your experience? Getting an amp tester today. Ugh
