I currently have an AC300 and 2 B300 batteries hooked up and it’s working well. I just ordered a third battery to add to the system. I know it’s very simple and plug & play, but could anyone show me how to properly hook up a third battery to the two I currently have on the AC300? Which port goes to which on the new battery I guess is my question.
According to all the AC300 images and the user guide booklet, the AC300 has two battery expansion ports, and each can manage two batteres in series (actuality there are in parallel). The B300 has two ports on its side to allow the chain to continue. So the correct form is to connect the first B300 to any of the AC300 expansion ports by plugging in with the P090A cable to both, then slide to cable lock forward. That has two functions, first to lock the release pushbutton out, and to signal the AC300 that a B300 is connected. Then the second B300 should be connected to the free AC300 expansion port. The third B300 can be connected to the first or the second B300 by using the second expansion port on the first or second B300 with its P090A cable. Then the last B300 can be connected to the remaining B300 by the same method. At the end you will have two chains of two B300 batteries on each AC300 expansion port.
In theory (which has not been tested) you can connect all four as one chain into one port of the AC300 and all four will be recognized and managed. Someone tried connecting a fifth B300 battery and the AC300 did not see it at all. The new AC500 can see six B300S.
