YES you can.  I'm sure there will be naysayers to follow who will loudly pr
oclaim that you should never mix batteries and that I am full of shit.  Don
't listen to them.    I wouldn't even have a problem mixing different batte
ry technologies if i studied up on them.

If you have any questions you can email me at powersupplyguy@netzero.net Be
tter yet I am Roswell Bob Lafrank on facebook.

Don't. Paralleled batteries are not a great idea. They are never
identical voltage so the higher voltage one wastes its charge
trying to charge the lower voltage one.

Use a battery isolator, etc.
