back to Sealed Lead Acid (SLA), 2.0v per cell

85AH SLA deep-cycle:




This is probably the cheapest option for large portable power. You could go to the junk yard and buy a used
car battery, but it won't last very long before you need to get another one. (been there) Just get one of
these and be done with it. They're usually classified "Flooded Lead Acid". (FLA)

You'll want to pick up a group 24 battery box to put it in, so it's easier to transport, keeps the battery
dry if its raining, protects in the rare chance there's a crack or spill, and gives you a little bit of
extra space for accessories like power wires, clips, power meter, and maybe a little 120vac inverter.
