I have the E-Go mower with 7.5A battery. I assume that battery would last *forever* in the trimmer. The 2.5A battery is only $30 extra at HD, and I assume it's probably lighter and easier to handle. Is it worth paying the $30 for a small battery & extra (unneeded) charger?
And then I'm thinking about the snow blower, and the chainsaw, and .... :-)
