Hi guys, this is my first on this forum and i would just like to say that i love all the projects you guys do.
so anyway, i know this is probably a really obvious question but i couldnt find the answer anywhere:
how do i work out the total volts and amps of a bunch of batteries of the same type linked together? like if i had about 14 1.2v 2300mAh rechargable AAs what battery would i end up with if they were connected together in a big sequence, [you know positive to negative through all the batteryies woth a wire coming from the first and the last one]
Thanks

Well, they can either be connected in series or parallel.
Series: All the batteries are connected end to end (+-+-+- etc), and the Vtotal is calculated by multiplying cell voltage * num cells. So in your case it's 1.2 * 14 = 16.8 volts. mAh capacity doesn't change, it still equals 2300mah.
Parallel: The batteries are connected in line with each other, with the positive ends all tied together and likewise with the negatives. The Vtotal stays at the cell voltage, 1.2v, but the capacities all add up. So, 2300*14 = basically a 1.2v battery pack with 32200 mAh. But 1.2v isn't enough to do much with though.
