    Double bms issue

    I will not be using the bmss for discharging, only using there p- cable for signaling on and off the contactor and for charging the pack. So I will be bypassing the discharge on the bms. I will take note of the charger isolation and make sure to check like you mentioned. And I figured it would...

    Double bms issue

    Thanks for sharing this. I'm really looking for something compact in size similar to the size of a automotive relay only because I would have to fit it in to the battery box, and in this case two of them

    Double bms issue

    Lol. I'm speaking to several people regarding the isolated step down I listed and they are saying it still won't work because the contactor coil requires close to 3 amps to close (turn on) and the step down is only 1w if I'm not mistaken.

    Double bms issue

    On a side note someone shared this with me. A isolated step down relay. Only thing I see is that it says max voltage 75v not sure if 84v would be a problem. https://www.tracopower.com/model/tdn-1-4821wi

    Double bms issue

    Amber appreciate the response although I am a bit confused with your answer and that might be just because I'm a visual learner. I will try to answer your points as best as I can. Firstly the bmss both are same port. So p- is used for both charge and discharge. As for testing the contactor with...

    Double bms issue

    Hello, would greatly appreciate help with my circuit that I have in mind. The objective of the circuit is to have two 72v batteries that are connected in series, both of which have a bms on them. Both bms will not be used for discharge and only for charging. Rather for discharge safety I have a...

    Double coil contactor

    Thank you for your input. Actually what I was looking for is if either of the two bms turns off I want the power to the main source off. That being said you still did give me an idea which might have resolved my problem. Thank you.

    Double coil contactor

    Hello question I have is there any double coil dc contactors? Reason for this is because If I have two bms I would like both of them going to one contactor to turn off the main load. Link below is one that I saw which has a set of 4 wires just wasn't sure if that's what I was looking for...

    High voltage bms

    I see what your saying but that's a bit complex for me to make that kind of bms. If something like that was available ready to buy I would look into it

    High voltage bms

    There's active balancing and then there's another kind I forgot what it's called. The active works much better from what I'm hearing/reading from people who have used both.

    High voltage bms

    This was the daly bms I was referring to. My concern with this is that daly doesn't have that good of reputation, and this one does not have active balancing if I'm not mistaken.

    Thanks for sharing this I've seen this one before and I'll keep it in mind. Wondering if there is anything of higher voltage.

    High voltage bms

    Hello anyone have a idea where I can find a compact high voltage bms? Looking for something around 35-40s. And obviously for a ebike battery it needs to be compact. I'm leaning towards something that will use a relay. What I have found is heltec makes one, but doesn't have any Bluetooth to view...
