How long is it? Description says 10.8 inches and manual states 7.8 inches.

Dear friends, I'm sorry, the size of this product is 7.8 * 4.1 * 4.3inch.

Can this be connected in series 24 or 48 volt?

Dear customer，thank you for the question. Yes , you can get 24 volts by connecting two of our 20AH outdoor lithium batteries in series or connecting four batteries in series to get 48 volts. Thanks again for the question, have a nice day!

It it normal for the voltage to decrease over time? my new battery v decreases from 14v to 12v over relatively short time frame - bad battery?

Yes, voltage will decrease over time. Nominal battery voltage is 12.8V. Charge voltage is higher, often 13.5-14.0V, but will decrease within several days back down to around 12.8V. This is quite normal.

Can this battery power an air pump that draws 28 amps? I only need to pump an small inflatable boat once per battery recharge

The 20AH battery can charge your inflatable boat once, but since the starting power of the air pump is relatively high, it is recommended that you use 50AH or 100AH battery https://www.amazon.com/dp/B09L89LW3P?th=1
