    Do you wire PPTC fuses in series with the balance wires?

    I have a thread exactly on this same issue, so maybe you can refer to it, in order not to duplicate the number of threads talking about the same issue: http://endless-sphere.com/forums/viewtopic.php?f=14&t=59145

    Questions about BMSbattery S06S controller

    So, do you think a q100h could withstand 48V at 18A, set by a S12S with the max amperage set at 18A (this can be regulated through the LCD, it is possible that it was yourself who pointed that out to me)?

    Questions about BMSbattery S06S controller

    Thanks fellow for your follow up. A S12S with the max current modified via LCD at 18A would possibly provide 48V @ 18A cheaply, right? It would be interesting if the Q100H withstands without getting too hot 48V @ 18A.

    Anyone tried EM3EV new bottle mount batteries?

    Thanks for the pictures, voicecoils. Quite helpful. A few questions: 1. I see 7 balance wires (one black and six red). I assume you have a 13s4p configuration. As a consequence, there should be 14=13+1 balance wires. Are the other 7 balance wires at the back (not visible in the picture)? It...

    Li-poly noob questions.

    I think I know the solution: join last pin of the first battery with the first pin of the second battery (and so on). These two pins should share the same pin at the BMS (the fifth).

    Li-poly noob questions.

    Having three 4s of these hardpacks connected in series (no parallel), one has three 5-pin (4s plus ground) JST-XH, so 15 pin. A 12s BMS has AFAIK 13 pin (12s plus ground). How is everything connected? Through a balance board?

    Fuses and thermal fuses

    Well, this is exactly what I am trying to do with this thread: learn! Life has taught me the best way to learn is to ask those who know. And this is what I am trying to do here. If every time we do not know about something, we should abandon, there would be no research. By definition, every...

    Fuses and thermal fuses

    KarlJ, thanks for your detailed answer. It is interesting the fact that em3ev has no output fuse. Instead, em3ev has balance wire fuses. So then, probably the balance wire fuses are there to avoid problems in a parallel "brick" contaminate the rest of bricks. And the BMS will act as a fuse if...

    Fuses and thermal fuses

    Mmm yes, probably I am over concerned. But at the design phase, I prefer to be over concerned rather than under concerned :) So, to sum up, the bare minimum is to have a fuse at the discharge cable level. Then, one could add fuses at the balance wire level, but this is not essential (I assume...

    Fuses and thermal fuses

    When you say "perhaps balancing fuses if design will require it": under which conditions will your next build require balance fuses?

    Fuses and thermal fuses

    OK, I try to answer myself, using the information from the following link: http://www.allaboutcircuits.com/vol_1/chpt_11/5.html First I consider the following statement from the link: "For our series battery bank, one fuse will suffice to protect the wiring from excessive current, since any...

    Fuses and thermal fuses

    Thanks agniusm, very detailed and precise answer. Just in order to fully understand you: in your post you say: "My current battery build has balancing fusing and main fuse" but also, at the beginning of your post you say: "I myself would go with single main fuse and be done with that" Can...

    Fuses and thermal fuses

    Thanks. Is there a place where I could see pictures of how good professionals put fuses in practice for e-bike batteries (at cell level, balance wires level and / or main fuse level)? I have done a bit of search at this forum, but I have been unable to find that. I am not saying this...
