    Works for me - I was assuming the same - it just works like one giant battery. I get that the Optimate is betterer...but then I could just use one of the powerstation batteries that has a 3pin plug and runs a normal optimate.

    tbh unless your bike is going to be sat there for a very long time,theres no real need for a leisure battery,any 12v battery will do (if thats the route you want to go) as the amount of drain on it from a bike wont make much difference,biggest issue this time of yr is temp,thats the real battery killer,so insulating it will help.

    i've got a spare lithium bike battery that gets connected to the bike if it's going to be away for a long time,a lot easier (weight_+ size wise) to take into house to re-charge when needed

    Bike is sat for months, under ground, tracker draining the battery. In a garage 1 mile away. Swapping the 2 batteries is a ballache.

    i dont mean swapping,i mean piggy back on via the existing optimate cables or an anderson plug
