LifePo safe?

I bought a load of them around the same time, and after just two events they're all puffed to hell, same happened to Shockwave; there seemed to be a dodgy batch right around Season 1. They'll run your robot fine without exploding if they're LiFE, but don't expect them to last too long.

Thanks Rory - guess what, I asked Will what he was using in Shockwave and bought the same! will doubling them up help do you think? two pairs in parallel to give 8s.
