    2x5s balance leads into 10s balance leads

    Sure will, might have a video coming too ;) Although I might put it together with duct tape initially until I have time to make it look good :D Here's a benchtest with power supply before I connected up the BMS and batteries to keep you happy for now :P QJt321varlY Thanks for looking out for...

    2x5s balance leads into 10s balance leads

    Thank you so much, will do the last soldering to the BMS tomorrow and hopefully all will be well! :D

    2x5s balance leads into 10s balance leads

    Now I've soldered the balancing cables. Could anyone confirm that pin 1-10 should measure ~34 rather than ~38 volts and that the last cell will be connected by BMS from P-? Is it safe to measure from negative terminal to the positive balance pin? If so, this should equal 38 volts, correct? That...

    2x5s balance leads into 10s balance leads

    Thank you! So just to double check, does this mean the black (negative) cable from the negative batteries balance lead is left disconnected (since this is connected via the P- anyway)? This would mean that when I measure the voltage from pin 1-10 I'd get only 34 instead of 38 volts, correct...

    2x5s balance leads into 10s balance leads

    Haha, ooops :D I have updated the picture to be smaller, the image is not cropped but you might have a smaller screen than me :P

    2x5s balance leads into 10s balance leads

    My 10s BMS has only 10 pins which is what confuses me to the point where I'm close to becoming crazy.. :? If that wasn't the case I would probably have it all wired up by now...

    2x5s balance leads into 10s balance leads

    I think I understand this. However I have 12 cables supposed to merge into 10. I understand the ones in the middle should merge into one cable leaving me with 11 cables, not 10. Can someone bring some sense into this?

    My e-board caught fire

    Thanks now I'm even more paranoid putting my board together :P Sorry to hear yours caught fire, hopefully the rest of the components are fine.

    2x5s balance leads into 10s balance leads

    Hi! So I finally have everything to get my board together. However I'm not 100% certain how to hook up the balance leads. Right now I have 2 5s packs each with 6 balance wires. I need to merge these into a single 10s balance lead with 10 cables. I think I almost got it but I want to be sure...

    Battery connection scheme

    Haha, I'm sorry about the colors :D Thanks for the help, of course I will connect balance wires as well, but as you said, they'd be a pain to draw.

    Battery connection scheme

    Hello, I have made the following scheme of connecting a BMS, batteries and an ESC. What I want to accomplish is to use BMS whilst charging only (therefore not connected BMS- to ESC). If someone could confirm it works or tell me I'm an idiot and why I'd really appreciate it. DO NOT care about...

    BMS confusion

    Haha, yeah I know the dangers are overhyped a lot of times. Running them on a relatively cheap BMS though makes me a bit worried. The original plan was to use LiPo and a regular balance charger but I feel like I have pivoted more and more towards a BMS since it's quite a lot easier to carry and...

    BMS confusion

    I've had my eyes on these for a while. Haven't really found any other with as big capacity as I want, they seem to be quite rare compared to LiPos. http://www.hobbyking.com/hobbyking/store/__14074__ZIPPY_Flightmax_8400mAh_4S2P_30C_LiFePo4_Pack.html As far as I understand they seem to be quite...

    BMS confusion

    Thanks for the info. While we're on the subject, are there any known stupid things you can do (other than connecting the batteries and BMS wrong)? Is it just plug and play with two new batteries? Hook them up to BMS and go or do I need to balance them manually or something first?

    Is a DIY E-Skate worth it?

    I got charged 74 euros in import to Sweden for two VESCS, you got off cheap ;) Regarding if DIY is worth it, I'm not sure yet since I'm not done building. There's always the balance between convenience/fun to build/price/just being able to send it on warranty when it breaks etc.

    BMS confusion

    I'm a bit confused regarding batteries and would really prefer to be able to have a small charger that I can carry with me. Therefore I have been looking at BMSes. My theoretical plan (which I'm not sure at all would work) would be to wire 2x 4s LiFEP04 batteries in series and connect these to...
