Rob,
Is the 240AHr a typo? That would be a big lead acid battery. After
inconvenient accidents with tipping and draining of wet cell garden tracto=
r
batteries, I'd suggest the more expensive option of ganging equivalent
capacity of smaller gel cell or AGM batteries. No orientation issues, easie=
r to
carry, more tolerance for deep discharge if the right models are
chosen/available..
