James,
My comments about the BMS are from my own experience with 48V x 100AH LifePO4 Battery Packs providing such excellent power for propulsion. Any change in the Battery Management System or changing how the Battery Packs are charged will only be made by the manufacturer HiPower New Energy. You have heard the phrase "If it ain't broken don't fix it."
I am not suggesting that the technology will always remain the same; I think HiPower will always be in the fore front of LifePO4 batteries and technology.

A good multi-stage charge is far far more important then a good BMS, There are large debates on more then a few electric car sites that say some BMS hurt instead of helping. The http://web.me.com/mjrickard/ EVTV host makes a pretty good case for no BMS at all. Though a good charger is not all that cheap either : http://www.evcomponents.com/ ProductDetails. asp?ProductCode= PFC%2D20 So you will need to pony up the dead presidents either way.On Dec 25, 2009, at 12:42 PM, Ned Farinholt wrote:Does anyone know how important it is to have a Battery Management System on a bank of LiFe PO cells. It adds considerably to the cost. I can understand taking the risk on a bicycle or motorcycle bank but in a boat, is it prudent?
