Hi guys

Occasionally I am forced to use my observatory Windows PC when not observing. This involves reeling out a 240V lead to the obs. I have thought of having a 12V batt and inverter in the obs to run the PC for brief periods occasionally.
I already have a solar panel keeping a small 12V SLA battery charged for the alarm - Can I charge two different sized batteries at once - I expect I should just wire another charge controller/battery in parallel with what is there? Is this right??

TIA
