Do! But do your homework and don't blindly listen to the "you have to have a BMS!" crowd or the "you should never have a BMS" crowd. Do your homework, very carefully. Do your own "playing around" with the cells you are going to use. See what others' results are with the same cells. Check out the theory on that particular chemistry. And definitely look for success stories and failures with those cells and BY ALL MEANS get all the info about the situation. Remember, several on this list told me that my pack would be out of balance quickly and ruined. Four years later that hasn't happened. No cell level BMS, only a Batt-Bridge like device. Remember, LiFePO4 cells have no self discharge mechanism so if you have one that self discharges it is defective. Lithium isn't lead acid. -- David D.
