Yes, you can use any battery pack without a bms. But, you must then monitor it yourself if you don't want to damage it. If all cells in your pack are equal. then in theory all you need to do is recharge the whole pack at once using a bulk charger set to the the max voltage of your pack. Assuming a 16s pack, that would be 16 times the fully charged voltage of your cell type. Or 58.4v for 3.65v cells. During the first few charges you should monitor the voltage of the cells to make sure they don't get too far out of balance. If they charge in balance good, then you can check it at random every few charges if you like. A better option would be to hook up a couple of those 8 cell balancers to your pack during charge. They make all kinds of cell monitors with alarms that go off when a cell gets to a set point. Those could also be used to monitor discharge so you don't over discharge the pack.UNDERLORD said:
