My Aerolithium battery was installed in serial #175 on 4/17/13. It was described as Aerolithium 12.8 volt, 12 AH, 1000A PCA LiFePO4 Andy Start .
The battery has worked out very well. 175 has the old starter. After a slight slowdown on the first compression, it spins the engine rapidly. I fly skis in the winter, although I preheat the engine.
I have equalized the battery a couple of times. Each time the cells were very close to equal when the process began.
