New 3.65v 35.2ah 128.48wh Boston Power Swing 8 Cell Modules

These modules have 8 cells in parallel. They have never been used and are overstock. They were built then never added into modules. All modules are resting around 3.55v. They already have busbars welded and are in cell holders. Doesn't get much easier to build these into packs of different voltages since there are tabs sticking out for the positive and negative on the same side.

7 in series makes 24v, 10 in series makes 36v, and 13/14 in series for 48v.

No they are not 2 18650 cells side by side. Boston Power is found in many medical and military batteries. They are one of the best and most certified. Certifications UN 38.3, UL1642, IEC 62133, ROHS 2002/95/EC In Process: Nordic Ecolabel

Note: on these cells the side that looks like the negative is actually the positive. The negative side is the one with the botton.
