What's the difference between battery connector types A & B ? Can anyone share pics please ?
Is it a physical difference (won't fit together) or just a pin-out thing (will fit but won't work) ?
Having a nightmare trying to source the correct batteries compatible with my existing installation.
[ I never realised that a "plug & play" modular expandable system would have so many different types of incompatible batteries which all look the same (and suppliers don't seem to know about). ]
