john a durden, would this internal regulator in each battery be a problem when put in series?

Thank you for your inquiry. The internal BMS of the battery allows for a 2s configuration for 24V, so you can put up to two of these batteries together in series without issues,

how much does each one weigh?

I didnt weigh them but the pair were lighter than one lead acid equivalent.

In your ad, 4 are connected in series for 48vdc, but elsewhere you state max 2. i need 4 in series for a smart2200rm2u ups. will these work?

The latest version of this battery does support 48V series wiring connection. However, we might not recommend using these batteries in a UPS system that has the SLA/ AGM batteries as the original batteries, because the built-in charger is designed to charge SLA/ AGM batteries that might not be able to provide LiFePO4 lithium battery sufficient charging and it might also cause damage to the batteries in long term use.
