Tested Ironworks 1240st 12.8v 44ah 573wh w/ BMS - 80-89.99%

Every battery is fully tested and comes with the printout of the test report which shows the capacity and charge/discharge graph. These batteries tested between 35.20-39.59ah which is between 80-89.99% capacity.

It is unknown if this model can be used in series. Most standard 12v BMS units use mosfets rated up to at least 30v so it is likely these can series connected into 24v. However, this cannot be confirmed since we can't find a datasheet online. These are popular batteries that are used in hospital medical carts.
