Great information AJ. I wish I had the nerve to take my streetrod apart and add two batteries when the time comes to purchase new.

I just ordered a Datel Digital Voltage Gauge from Scottyb's Carts Unlimited. Mounts in dash and gives a constant accurate pack voltage digital read out. There's a lot of information about the guage on Buggies Gone Wild. With this guage you would be able to tell, according to the chart put out by Trojan, exactly where you are on battery usage. In other words be able to tell when the pack is near 50% discharge etc. I'm hopeing the digital guage will be better than the yellow warning light or the red and green colored needle guage.
