    Need help with Overkill Solar BMS

    Yes. Either one works fine on its own, but if I connect both, one doesn't pass current. It's the same one every time, and I bought a new bms, and it does the same thing.

    Need help with Overkill Solar BMS

    Just to add a little more info - saw that overkill had someone hook up just the bad bms, so I did. It works fine. As soon as I hook the second one back up, it stops working again....

    Need help with Overkill Solar BMS

    OK, so I had my setup running for over a year with no issues. It's two 560ah batteries (eve cells), run in parallel with an Overkill solar 120amp 12v bms on each battery. Last fall, my inverter started kicking out on charging, and inverting. Just a few times, and I thought my inverter was going...

    Top balancing, recommendations (fastest or best practices)

    Well, I'm definitely not a battery chemist, but I am pretty familiar with electrical theory. I did read the article, and I don't quite follow the premise. It's showing different starting voltages, which should not be possible with all the cells in parallel (as long as they have been given time...

    BMS question

    Thanks for all the replies. So now I have another question. If I wanted to upgrade my charger/converter do I need a new power center? It looks like the converter is integrated into my power center. If it's possible, is there one that will let me set the charger to cut off at 85 percent? Also...

    BMS question

    I am pretty new at this, and plan to switch from two 6v golf batteries to a diy lifepo4 setup. Will the BMS allow me to set the charge cutoff and discharge cutoff to I run my battery from say 10 percent SOC to 85 percent SOC? The BMS I am looking at is the 120a from overkill solar. If that won't...

    Would you pay a $700 for 4 tested 280Ah lifePo4 cells that could be delivered to CONUS within 1 week?

    Interested in 8 cells shipped to 98629, if you are still shipping.
