You freakin rock, that’s exactly what I was looking for. I personally will be cycling them every day as well. Not fully, but they will be charged up/ loaded during the day and then minimally loaded over night. I’ve seen so much conflicting information online about the float settings for a...

i have a 12s 44.4v battery actually, I was just using the arbitrary 48v value for conversation. My 44.4 has a max SoC of 49.8, however I am only charging it to 80% or 47.1v to extend cell life and safety.

Great advice, thank you. Im glad to hear my thinking was going in the right direction. I spent the night playing with the AC input limit and power assist. Ive got it to where i can run a 4000 watt load with 1000 from the grid and 3000 from the batterys/solar with power assist. Sounds like this...

Yes, each of the 12 series cells of 29 parallel cells is monitored for over voltage

Hey guys, I have a Victron multiplus 24/3000 that is powering more than 75% of my house via a sub panel. I do have the multiplus AC tied, but use assistants to ignore the AC input based on battery SOC. What i am looking to do however is to get the multiplus to "assist" the battery/solar from...

Great, i can get on board with all that. As far as the settings on the victron charge controller however, it’s got bulk, absorption, float and tail current. Any ideas of good settings for those? I appreciate the help

Good eye! His reccomendation was correct based on my specific manufacturers specs on this battery. For a 44.4 nominal it’s got an abnormal min voltage of 38 and max voltage of 49.8 But good to mention for others that may see this

Okay guys, my overthinking brain is getting the best of me and I need an explanation of whether this thought is right or wrong. Let’s go with a standard diy setup hypothetical situation here. You have a solar array connected to a charge controller, and CC is connected to 48v lithium battery...

Okay so let’s take it one step further. Let’s say somebody is using a variable bench-top power supply set to 48v that is feeding the battery instead of the charge controller in the above scenario. The bench top power supply will cut current when set voltage is reached. So the battery is now...

That makes perfect sense and is exactly what I was looking for. Setting the float LOWER than bulk allows a safety buffer where the inverter is only pulling from battery and doesn’t allow my concern above to take place. What charge controller are you using? Feel free to dm me any pictures of your...

Okay that makes sense! So when the controller switches to float or “constant voltage”, it will maintain the batteries 48v, but allow the actual current to the load to be fed from only the battery’s? Does the above post from FLD make sense with having the float voltage set to lower than bulk to...

Hey all, looking for some extra reassurance on my calculations for bulk and absorption settings on my victory charge controller that’s charging a 12s29p 44.4v NMC battery. The battery specs say max charge of 49.8v and discharge cutoff of 38v. If I want to give a little buffer zone of safety...

I can measure the 12 series packs voltage but not individual cells. BMS does an excellent job and has each series pack at 3.70-3.701

That is correct. It is a generac pwrcell pack. Here’s a picture back when I had them opened up

Each 12S pack is controlled by BMS. This is a generac Pwrcell unit. Here is a picture (not a good one) of the BMS.
