I have an old futaba attack 4 system that I'm planning on using in my next plane. The problem is the RX and TX battery are dead and won't hold a charge. So i've decided that I will just get 13 of these batteries, [link]http://www.greathobbies.com/products/productinfo.php?prod_id=SAN070N[/link] the question is if I take five of these and solder them together will that give me a 6 volt 700 maH battery or a 6 volt 3500 maH battery.
