Circuitikz: Battery label placement removing polarity labels

Question

I am using Circuitikz to draw some diagrams involving American batteries (battery1). By default, it includes the polarity, but it places the label partially overlapping it. (See the top image in the diagram below.) I would like to move the 50 V label to below the battery. When I try to do this using either l_ or a, it does move the 50 V label, but also removes the + and - indicating the battery polarity (see the second and third diagrams below). I'd like to move the label but keep the polarity. How can I do this?

The code below shows what I have tried:

    \documentclass[border=3pt]{standalone}
    \usepackage{tikz}
    \usepackage[americanvoltages,fulldiodes,siunitx]{circuitikz}
    \begin{document}
    \begin{circuitikz}
    \draw  (0,0) to [battery1=$50 \, \mathrm{V}$] (3,0); % Polarity, but label above
    \draw  (0,-2) to [battery1,a=$50 \, \mathrm{V}$] (3,-2); % Label below, no polarity
    \draw  (0,-4) to [battery1,l_=$50 \, \mathrm{V}$] (3,-4); % Label below, no polarity
    \end{circuitikz}
    \end{document}

Answer 1

Use a "blank" voltage and a label (also fixed warnings and used siunitx correctly):

\documentclass[border=3pt]{standalone}
\usepackage[americanvoltages,fulldiodes,siunitx, nooldvoltagedirection]{circuitikz}
\begin{document}
    \begin{circuitikz}
        \draw  (0,-4) to [battery1,v_={~}, l^=\SI{50}{V}] (3,-4); % Label below, no polarity
    \end{circuitikz}
\end{document}

You can use v_, v^, l_, l^ for the above/below position.

The overlap was at least partially fixed in one of the recent versions of circuitikz (This is why I have no overlap here: this is with version 1.2.3).

 \draw  (0,-4) to [battery1,v=\SI{50}{V}] (3,-4);
