    Do I have to solder on a Y shape?

    Coming back to this old thread since I now have gotten the BMS and the battery and most of the things in place, and also have some time over finally. The battery is almost finished. Anyway I have soldered on all the balance leads from the Daly BMS. The reason I asked about an active balancer...

    Anyone used this discharger?

    Active balancer for 13s?

    Hmm I found connectors that look like the ones in your image here...

    Active balancer for 13s?

    Hmm you install an active balancer instead of a BMS? :) Have it there instead of the BMS? What is the difference between that and a regular BMS? What are the pros and cons? I also thought about that but I read somewhere it had some downsides but I cannot remember where I read it and what were...

    Active balancer for 13s?

    Aha works like a balancer right? Just connect it manually or something right?

    Active balancer for 13s?

    I have measured both now. One shows 55,2 the other 54,5

    Active balancer for 13s?

    How do I balance using a bulb? I think I might have to do that just to make sure they are very balanced. Since I am using a Daly BMS(red one passive balance), and I do not find an active balancer for this particular BMS.

    Active balancer for Daly BMS?

    I am also going to solder on the charging cables for Daly but i got a bit confused by the fact it has no C-cable attachment. So should the charging port be soldered onto both the main discharge wire negative and the main discharge negative positive? Or how are those two soldered on there? I have...

    Active balancer for 13s?

    Yes I think it does cut charging earlier. Perhaps but I am not sure. This is the instructions for it if it tells you anything. Mine is the one circled in green of 13s40a.

    Active balancer for Daly BMS?

    Anyone knows if there is an active balancer for Daly BMSes? I mean the red type that has a passive balancing function. Do you guys know if there is an active compatible balancer for these ones? I would like to balance the next pack before I insert the balance wires but haven't found an active...

    Active balancer for 13s?

    I changed batteries in the multimeter and one of them now charges to 53,8 and the other to 53,3. I guess this might also be normal since these batteries have been used for a log time. Might not necessarily be unblanced. Could also be wear on the cells right?

    Active balancer for 13s?

    I have charged it up with two different chargers (and gotten the same result) now, so I guess it is probably the multimeter ? I will try to change the batteries in it later.

    Active balancer for 13s?

    I have now measured my other battery and I think maybe the multimeter could have drifted out of controll. Because it shows 53,3 for both these batteries at fully charge. Any idea why? Do they degrade over time these mutimeters I suppose?

    Active balancer for 13s?

    Yeah but this was the ball park. They were very close. I do suspect this could be an issue with one of the cells though that I might have missed. Chatgpt says that if one of the cells has bad internal resistance it might reach 4,2 volts much earlier making the BMS shut off charging. Perhaps...

    Active balancer for 13s?

    Hmm leave the charger in there you mean? Even though it has turned green? The BMS might try to balance even if it has turned green yeah? 👍

    Active balancer for 13s?

    They were not far apart before charging.

    Active balancer for 13s?

    Yes I measured both actually. Also the balancer has like a blinking red light for the groups that are out of balance. When those lights turned off it was balanced. I measured both in the pins and with mutimeter going over all the cell groups. But this was around 44 volts. It could have possibly...

    Active balancer for 13s?

    Hmm ok. Thing is I also used an active balancer. So I am not sure what is wrong now. I did balance the groups when it was around 44 volts. Putting the connector pin of the BMS into the active balancer. When it was balanced I put it in the BMS which is on the battery now. Then I taped it up and...

    Active balancer for 13s?

    I have charged it up full to green light. Only goes to 53,3 it seems. Any idea what it means?

    Active balancer for 13s?

    I normally have a habit of not charging batteries full because I have heard that this hurts the cells over time. But for this purpose it would be good to charge it up full and leave it there for a couple of days right?

    Active balancer for 13s?

    So realistically it would be best to charge it up full? Until it turns green right? Then the balancing should begin? If everything works as it should do right?

    Active balancer for 13s?

    I have rode the bike with this pack. Not completely fully charged yet but it all seems to work now. When charging it full it should go up to 54,6 correct? I think this is the correct voltage for 48 volt packs correct? Are you good at explaining the function of the BMS too? What this will do is...

    Active balancer for 13s?

    Hmm charge it to full and thendisconnect the BMS you mean? And check inside the pin connector if the cell groups ll have the same voltages and increase at the same rate? That is what you mean correct?

    Active balancer for 13s?

    I have measured a couple of ways. Like from battery minus inside the case to main dicharge port +. Then the other way around. They all show 46,1 volts now. I also tried charging it a bit, which is the reason it is now at 46,1 volts and not 44 anymore. So I guess this means I am good to go...

    Active balancer for 13s?

    It looks like this the thermocouple. Byt the way do you know if the text side should be against a cel or the other way around?
