Thank you for this information. For the MMM, do you have a minimum voltage drop which is acceptable, like 3.4 volts/cell? Or maybe it's a measurement relative to the packs voltage at that point in the run. For example, require that full throttle only produces a voltage drop of 0.5 volts/cell.
I'm very interested in finding packs that won't harm my MMM, and I want to be able to monitor the batteries through their life to verify they're still meeting the minimum requirements. Even the best cells will eventually start to have more and more voltage drop. How do I know when to throw them away to protect my MMM? I'm sorry to put you on the spot, but I would really like an actual number. I understand it's not a guarantee against anything going wrong, but I would value your opinion on this.
