Edge 494 with this controller, does it support adding lithium.

May be getting 2020 Edge 494, I know about Lithium but does this Sergeant unit support with regards charging.
I can add B to B later.

That looks like an EC800 control panel which will be linked to a EC6xx PSU which is in turn linked to a separate Sargent PX300 charger , the information about these units can be found at www.sargentltd.co.uk in their support section which should help with answers to your question

Read all manuals regards changing to lithium battery, does anyone know what the choices are for A B C.

If you google , NCC Verified Leisure Battery Scheme , there is information regarding leisure battery A,B and C types ( the Halfords website is one source showing this information )
