Can you wire 3 batteries in series and parallel?

like if you wired batteries 1 and 2 in parallel but batteries 2 and 3 in series. So lets say 3 6v 10 amp batteries, would it it turn out to 12 v 20 amps or do you truly need 4 batteries to get that done.

    You could - but the single series battery would still discharge twice as fast as the parallel ones, and as all the current must flow through that single one, you cannot draw more than with just two together in series anyway.

    If they were rechargeable, with that setup of three the charge states would get messed up as well...

    There are no advantages and serious disadvantages.

    Use two in series or four in series-parallel.

    Probably.

    What would you hope to accomplish?

    In series, the current stays the same as a single battery capability. In parallel, the voltage stays the same and the current adds. Batteries 1 & 2 capable of more current. Batteries 2 & 3 in series brings you back down to limiting the total circuit current because of battery 3 (the weakest link)

    if each battery 3.6 v 10 a ...then

    three batteries in series (10.8 v )... two groups in parallel

    if you need exactly 12 v ... use four batteries in a group and a voltage regulator board

    Batteries in series don't allow more current to flow

    than the least capable one can pass,

    which means that two 6-volt 10-amp batteries in series

    will provide 12 volts at a maximum of 10 amps.

    If you had one 10-amp battery and one 7-amp battery and connected them in series,

    the maximum current available would be 7 amps.

    Batteries in parallel can deliver more current,

    but not necessarily the full sum of all of their capabilities.

    Batteries in series adds up the volts. Batteries in parallel adds up the amps but the volts remain the same.
