Adding a battery

I currently have a Renogy 12V 200Ah Rechargeable Deep Cycle Pure Gel Battery. I see that Renogy no longer sells this type of battery, and some Amazon and internet searches do not give me any promising results either. So my question is, can I mix other types of batteries with this? Or would it be better to start with all new type. And if a new type, what is the best, most affordable (no Li-ION for me) type to get. Thanks.

  • it best not to mix batteries of different chemistry or age!

    Look into flooded 6v golf car deep cycle batteries, 2 in series = 1 12v @ over 200ah, charging voltage/care is higher than gel. sams/costco have good prices on adequate 6v, Trojan is good brand. For AGM look at LifeLine.
