I am waiting on my new Reo Grand and the batteries that I ordered the other day. I just want to make sure that the batteries that I ordered to try at 6v are the right ones. AW LiFePO4 3 Volt Lithium Rechargeable Battery They say 3 volt, but also say 3.2v max output. Is my thinking correct that 3.2X3.2=6.4v? Is that too high? Thanks.
