If that's two of the allowed batteries, then one of them is definitely illegal. If it's one split in half, that would probably place it under the "illegal" category due to it no longer being identical to the legal battery. <R92-C> bans more than one battery and non-identical batteries (save the fuse replacement).

You might be able to do it if one of the batteries was not connected, but that is still a violation of <R92-C>.

I'm not going to ask whose it was, or who let it onto the field. But if they read this, then I might suggest replacing one battery with an appropriate mass of an allowed material--and the other with a fully legal battery--or moving the battery location.
