    Unbalanced discharging of LiFePo4 battery packs

    Problem is I have 10 12v packs and the drop is happening on the 5 packs connected to the positive bus bar. Cells are new (old stock) Fullriver 26650.

    Unbalanced discharging of LiFePo4 battery packs

    I am putting a small 100wdischarge of my 24v LifePo4 battery setup. Each bankof cells is 12v in 4p19s configuration, so I am putting 2 banks in parallelto get 24v for my 24v inverter. With this loadthe banks discharge unevenly. What do I need to do to fix this?

    Settings for a Tracer 4215BN-MT50 MPPT charge controller

    Hi, I'm charging a bank of 24v LiFePO4 with aTracer 4215BN-MT50. What settings do I use? I am using the MT-50 interface in User mode so I can change the charging values. This is what I have so far. I am trying not to overload the cellsto prolong their life. I estimate I have 2000Ah total. I...

    12v and 24v loads on a 24v powerwall

    I appreciatethe responses; glad I reached out before continuing. I'll consider getting a2000W 24vpure sine waveinverter that I can run loads without using my main breaker panel. At this point I just want to get it working!, spent enough already. I don't have a BMS, I think the Batrium solution...

    12v and 24v loads on a 24v powerwall

    I need some help confirming the wiring on this project. To recap from other postsI have 10 packs of LiFePo4 calls, each with 12v in 4s19p arrangement. I am going topower a 6000w 24v inverter to run loads in the house when I lose power during a storm in Florida. I have an interlock which isolates...

    Wiring size LiFePo4 confirmation

    Here is the link for the busbar: https://smile.amazon.com/gp/product/B00821YF1E/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 Its rated for 250A

    Wiring size LiFePo4 confirmation

    Thanks for the information, it puts it all in perspective. I do not plan to use anything like the max rating of the inverter to avoid over discharging the cells, but wanted the cabling to be adequate. I'll probably upsize the cabling a little from 10awg to 8awg to minimize losses and use a bus...

    Wiring size LiFePo4 confirmation

    Sorry, here is the picture. Correct, trying to keep cabling linear. Should I instead run all cabling to a busbar with studs that I can attach the cabling lugs to and from there to the inverter? All cells are LiFePo4.

    Wiring size LiFePo4 confirmation

    I am installinga Lifepo4 24v system to run my 6000w/18,000W surgeAIMs Power inverter to run my house when I lose power after the next hurricane in Florida. I have mounted battery banks on the wall and calculated the wiring sizes but needed someone to check it over before I order the wire. I...

    Connect nickel strips to bus bar?

    I am building a powerwall with 760 fullriver lifepo4 cells arranged in ten 12v modules of 4S19Pto be used on a 24v pure sinewave inverter. I am spot weldingnickel strips to the cells to do both the series and parallel connections. The parallelnickel strips extend past the modules to provide a...
