Just changed motorhomes and being 'a bit of a scrooge', I removed the 2nd Leisure battery fitted to my former 2 year old motorhome with a view to using it on the new one. Trouble is, the "older" battery is rated at 100Ah and the battery on the new MH is rated at 90Ah. The batteries are also different makes- although they are both proper camping leisure batteries.
Can anyone tell me how they should be connected and whether they need any fuses (or resistors) between them?
