OK, looking for folks already using an AntiGravity battery, who may or may not have checked their charging system.
I received my ATX-30RS battery and optimate LFP charger as recommended by AntiGravity. Before I charged or installed the battery, I read the instructions and safety precautions. It states that the maximum charging voltage is 14.4 V on p 1 and and it says to "Test for properly operating charging system in your vehicle by a professional. Vehicles should never charge above 14.4 V." on p 3. I started my NSX with an old battery (reading 12.5 V) and then checked my voltage. My volt meter reads 14.8 V (presumably charging) at the battery with the engine idling. Do I have a defective regulator or alternator and will this toast my AntiGravity battery?
Note: I was asking about voltage on my battery last summer when my gauge seemed a bit high, but concluded that the gauge was just reading a little high. Back then I was measuring 14.6 V at the battery and the service manual says up to 15 V is within spec. It's been working fine with my regular lead acid battery:
I'm planning to call AntiGravity on Monday, but how do I reconcile the service manual being OK up to 15 V and AntiGravity's spec to not exceed 14.4 V?
Thoughts?

How much voltage is too much?
Search on alternator and regulator turned up empty, with most complaints of low voltage. My car starts and drives fine, so I'm not sure there's a problem. All I could find was: https://www.nsxprime.com/threads/do-i-need-a-new-alternator.216688/#post-2040687 Driving around & noticed that my volt...
