well the mfg's may be trying to force lithium batteries onto the market saying they are the best but i've seen them burst into flames while charging. So with that said there's no way i'd trust that technology. Lithium is highly unstable imo, so no matter how they say they have it put together i'll never trust it.

With all the past history of laptop and cellphone batteries exploding and bursting into flames i'm shocked that these companies would even consider making one on this large scale for lift trucks.
