I have not seen a chart that shows charging rate vs total lifetime, or total kWh over the life of the battery. Be nice to know if higher rates improve, cut, or have no effect on the life.
I bought my batteries 3 years ago from electriccarpartscompany.
It is not plug and play. But, experience and knowledge allow me to run my system without all the built in controls.
A BMS does four things... bottom cell balancing (which my batteries do,have built in), battery balancing (purchased separate devices which wire to each battery and then to each other) LoW/high voltage cut off..which I explained earlier in the thread, and temperature cut off...again explained in this thread.
The whole system (with balancers, relays and switches) cost me $2300 for 400ah. Or just a bit less than $600 per 100ah. At that time battle born wanted about $1000 per 100ah.
I think I have been seeing over the last year or so a drop in prices. Maybe when I need to replace in about 10 years it will be the cheaper choice.
