got a odyssey pc925 on it right now was just looking for a lighter battery but need some thing that will last through a race

When you look and feel one of these little lithium batteries you say to yourself no way. But they really pack a lot of juice, so to say. Look at your drill or impact, there is no way 10 years ago they would work as hard and as long as they do today.

Now the reasoning for 2 batteries. You are running a total loss electrical system. Sure you may charge it for an hour or so between races, and that will probably be enough. When you run into a bunch of yellow flag laps or other delays in the race that charge may not have gotten the battery all the way to full charge. The engine will run fine for these caution laps, but I can't think of a worse feeling than being in front of the pack and when you get on the gas when they drop the green flag that old motor falls flat on it's face. Took me two times before I put a generator back on and haven't had a problem since.

The other reason is them batteries go bad ever so often and when they do it is nice to have a spare. I know a guy that was sitting in the chute on the front row for the start of the B main at the Chili Bowl and his battery takes a dump and no spare handy>

Somebody said someone already makes on in previous post. When You depend on electronics you need a good hot battery, when they fall off a couple of volts you got big problems. Murphy's Law states that you will be in front when it craps.

This is a very accurate statement. Nothing like standing on it and it feels like you hit the brakes instead..... :(
