    Lithium ion 18650 charging cutoff current on a large battery bank.

    Sure, I'm familiar with that. I use 3 amp per cell fused buss in any parallel string. I'm talking if you have even a 4S4P battery and each cells cutoff current when charging is 50ma. When charging a 4P battery is the cutoff 200ma? I wouldn't think so, but nothing I have read says.

    Lithium ion 18650 charging cutoff current on a large battery bank.

    I've been looking into it also for a while. Haven't found anything yet. I thought there might be a formula for it. I appreciate anyone else looking into it. You would think that the guys building large power walls with 18650s might know from experience. Ken

    Lithium ion 18650 charging cutoff current on a large battery bank.

    Thanks Cody, it's something I've looked into and cannot find the answer to. I'm curious how it should work out..

    Lithium ion 18650 charging cutoff current on a large battery bank.

    I started building some 18650 batteries. I'm quite familiar with almost every about them but I'm not sure of one thing. I know that when charging one 18650 cell the cutoff current is around 50ma + or -. How does that translate when you have a large bank. Say you have 10 in parallel. You...
