These batteries usually sell for more than double. If you have a Deep Cycle battery and haven't considered lithium because of fire hazard then please read up on the LiFePO4 chemistry. They don't have the same thermal runaway properties that Lithium Ion batteries do. Much lighter and a lot more usable capacity than a Lead Acid battery with equal rated capacity because you can run these down to ~30% charge with little wear on the battery. They like to stay between 30-80% state of charge, which is much different than Lead Acid.
The one thing I am not sure about is charging this battery when it's very cold. The datasheet mentions "Temperature protection" but doesn't say if its a low temperature thermal cutoff switch. Some manufacturers advise not to charge these types of batteries below freezing (0C). The datasheet is linked on the product page.
These are out of stock for delivery. I'll take this down for now.
