Lithium and Flooded lead acid are totally different chemistries and while both should have a BMS, the settings, voltage, temp, charge time, amps, etc are totally different. It is rare that one BMS will satisfy all chemistries.
The best thing is to do a web search for 'BMS for Lead Acid'.

Mike,
Would you recommend the same thing for my Trojan T145 F.L.A. batteries? If so, what system would you recommend?
Thanks,
Chris

Eric was correct in his response. I noticed the same thing but did not respond as I thought it was a casual misstatement. The BMS system is not built in to any cells even with LiFePO4 but they are connected to the cells. The best marine specific built batteries have them included in their battery packs and anyone who spends the money of LiFePO4 batteries should always have a quality BMS.
As we have begun re-powering larger boat with larger battery packs and marine gensets, we have been recommending consideration of the same battery management system that is critical for LiFePO4 batteries also be incorporated in large AGM packs. Rather than monitoring individual 3v cells, monitoring the 6, 8 or 12 volt batteries themselves. It would also be prudent to use chargers that monitor heat both at the charger and at the battery. Using alarms would be wise as too much in your face data going to the helm could be distracting.
Just applying good practices.
