You are purchasing one used BMW 330e/530e/740e/X5 16s 1.5kWh battery module. Cells are made by Samsung SDI. These high power battery modules are perfect for an electric car, DIY EV, eBike, eScooter, eMTB, eSK8, golf cart conversions, solar energy storage, battery backups or UPS, powerwall, RV power storage, etc. Which is why they are so cheap!Therefore capacity and other specs on this listing may vary. The modules we have in stock are stamped with a date code from July of 2018. Fully assembled battery module, ready for use. Integrated BMS balancing unit w/ locking balance harness connector. Compact, high power energy modules. 16s1p (16 cells in series per brick).
3.65V per cell - 58.5V per pack. 4.15V per cell - 66.4V per pack. 26Ah per cell - 26Ah per module (actual capacity may vary). 94.9Wh per cell - 1518.4Wh per module (actual stored energy may vary).15" x 7" x 4 (380mm x 180mm x 100mm) - 29lbs (13kg). Yes, passive balancing via detachable, repositionable unit. Yes, basic voltage probe to check for dead (0.0V) modules. Module/pack is at proper storage voltage. Individual cell voltage has not been tested and is not guaranteed to be balanced.
Testing battery modules adds labor cost to every pack we sell, and the more in-depth the testing, the higher the labor cost. If there are no test results on a product listing, it's because we don't want to pass those costs on to you! If there are test results on a product listing, then we have completed those tests on every one of those products in our inventory (unless stated otherwise).
 Rated Discharge/Rated Charge are measurement results of the Batemo battery laboratory.  The continuous discharge current is the highest current that completely discharges the cell without over-heating it. Therefor, the cell is discharged from 100% state of charge at an ambient temperature of 25°C with a constant current until reaching a residual state of charge of 10% and either the voltage of 2.5V or 90% of the maximum surface temperature of 54°C.
 The peak discharge current is the current the cell can deliver for 5 minutes. Consequently, the cell is discharged from 100% SOC at an ambient temperature of 25°C with a constant current until reaching either the voltage of 2.5V or the surface temperature of 60°C after 5 minutes. The thermal boundary condition is free convection. , we will make it right. We want to make sure our customers are taken care of, because a happy customer is more likely to honor us with their business again!
