I ordered the WattCycle 12V 100Ah Mini Bluetooth yesterday from their Ebay store. Initial price was $10 higher than on their website but Ebay had a coupon for $40 off. Total price including tax and free shipping was $202.

I ultimately opted for this battery because it is the only mini version that had the bluetooth feature and it does have the low temp charging protection. I was leaning towards the Power Queen group 24 with bluetooth, however, the group 24 is about 1/2 - 3/4" too big to fit inside the compartment opening and I didn't want to have to trim it out any larger. Plus the WattCycle has a 7 year warranty as opposed to a the 5 year most of the others in this price range offer. There were plenty of positive reviews of both teardowns and load tests on this model so I feel confident in the quality. My only hesitation is that the Power Queen bluetooth app looked better.
