Title: 2 6v 7.2ah for 12 volt?
Post by: scb on October 20, 2005, 07:53:25 PM

i have 2 12 volts, but they're old and have been used like 2 times in the past 15 months, plus we all know a 12v 7ah is bulky

i'm thinking i might make a power cable that'll take 2 6v, connect them in series, and give a 12v output.  i figure i just make a connector with 2 male 4 pin xlrs and 1 female,  so it'll be able to take any 2 6v and give a 12v output.  has anyone done this?

how efficient is this?  same as running 1 12v 7.2ah?

Basically...

Series = add voltage, capacity remains the same
Parallel = add capacities, voltage remains the same
