I was just looking into this recently. There appear to be two types of cheap
BMS systems, ones that just equalize when the batteries near full charge (put a
small load, 40-70mv, on cells when they get over 4.1V) and the other type is
typically called an "Active Balancer" it runs continuously an
For just a few batteries, I'd look at what the Radio Control guys use. I
think they have built in BMS and some are programmable.Being as you are only
going to have 4 (for 12 volt trolling), I think you could get a complete
solution cheap. I think they use differentterminology like "4S" for
Thanks all for the advise and ideas.
I joined the Electricboats list - excellent resource! There is also a PlugBoats
website/journal which looks good.
I borrowed our electronic load from work and will cycle a few batteries to see
what I have. Good to know it may take a few cycles to see where
I don't know anything about BMS's but Lithium Iron Phosphate cells can
experience capacity fade even if they have good voltage. I had some cells that
sat around for a year and a half and showed good voltage but when I cycles them
they only had 45Ah out of 100Ah they started with. I thought I ru

I guess this may qualify as an old-school question now.
About 12 years ago I built an electric motorcycle. I actually had it up and
running, but other things got in the way and I am abandoning the project. The
