The tail current goal changes as the charge rate changes, correct? I’ve played with settings and was able to monitor the green flash opportunity as the controllers all acted out their roles today. I was charging along at 14v and between 40-55amps today. The bank is 920ah, so about 0.05C...

My BMS units are sealed within the batteries and not accessible in any way. I’m not looking to program something to monitor charge rates and volts and make changes 100 times a second so I can get the batteries to some unknown perfect charge. I’m looking for the voltage or combination of...

That’s the question, and we really won’t know if our batteries last 30 years but could have made it 35, or if we added 5 years to them. I guess nobody really knows. What I do know is I’m going against Victron’s LifPo profile, LiTime’s settings, and going with this group’s advanced thinking...

Let me add: I went and reread #51 which addresses charging at various C levels, but doesn’t address charging at all those varying C levels during one day. While it’s possible to follow a charging protocol based on a C rate, I have an infinite number of C rates going all day long, from 0.25C down...

Okay, then let’s change the parameters so my question becomes valid. I can set my Victrons to turn off at a set voltage, I’m looking for that voltage. If I set them at 3.5 or 14v for my system, they will continue to provide charging until the batteries reach 14v. If that charge is a low amount...

Sorry I’m so late to the party, I’m also an engineer that is obsessed with finding all the facts one can. Where did we leave the simplified version of how to love on our expensive batteries?? I understand the 3.5v but get hung up on the solar aspect of varying C rates. My system is 920ah and...

Hans Christian 48! Small world, we probably have talked before, I have a Christina 43. I installed my solar panels 2 years ago and went with 3 LG 385w panels that will easily put out 410-420w each. It’s a shame LG quit building panels. I was running those into a carbon-foam battery bank until I...
