    Something very wrong with a cell

    @dnmun way i see it,the battery is less than optimal. I can send it back and they will replace it. i will test the BMS when i get the other cell. i have a second BMS that I can replace the current one with if it is also faulty. Considering the test was done with no BMS connected and the behavior...

    Something very wrong with a cell

    @amberwolf you pretty much describe exactly whats happening. i have already contacted the supplier as they are only 6 months old. i also ordered 2 spares in case this occurs again. Thanks for taking the time.

    Something very wrong with a cell

    the pack has been running for a 6 months and once a week I have been testing all the cells individually and in series. Just the other day it did this. Could it be the cell just died?

    Something very wrong with a cell

    ok dont understand but found how it displays that high, if i attempt to charge it the charger does not kick off but the volts climb to 42+. they stay there until I turn off the charger and they will reduce to .31 (circa)

    Something very wrong with a cell

    now its showing .31 volts. i tested it out of the series and whilst in it and even when charging seperatley it cut off. Going to take it back down stairs and see if it charges now ALSO READ THE TITLE "Something very wrong with a cell" The volt charge keeps going all over the shop and I am...

    Something very wrong with a cell

    ad I meant what the full pack registers at not a single cell. The cell is the first on the negative end if that matters (-) -|42.9|- -|3.38|-|3.38|-|3.38|-|3.38|-|3.38|-|3.38|-|3.38|-|3.38|-|3.38|-|3.38|-|3.38|-|3.38|-(+) Thats what it looks like

    Something very wrong with a cell

    The board runs with and without the bms attached for a few seconds. no it isnt a typo 3.37 - 3.38 except for one cell which reads 42.9 thus the title Something very wrong with a cell it is a 12 cell 3.2 volts 10 Ah pack

    Something very wrong with a cell

    I recently ran my headway 36v 10ah Headway battery back till it cut out. I thought it strange as I got substancially less milage out of it than usual. (It is on a skateboard) I charged it at workl and due to running around for meetings it the green light was on for about 1 hour with the...

    Turnigy CA120-70 Brushless Outrunner

    HI i bought a E-glide GI (second hand but they guy had never used it). I replaced the battery pack with a Headway 12s 36v+ 10ah and now understand the motor sucks. Its a 1000W brushed motor and it was obviously put on there for 'i have a big motor' wow and not efficient or power Does anyone...

    BMS setup

    @ dogman I had one of the electric engineers at work check it out and being an uber nerd, didnt look at the instruction. Just asked me a few questions then mapped the entire BMS with a multimeter into CAD checking the specs of all the components from the manufacturers spec sheet. Its good...

    BMS setup

    Thanks for taking the time. The reason it was confusing as it had B- and P- on the lower board and that was it. Reading through your posts here it makes sense now. The documentation that came with it was at such a level that if you understood it you wouldnt need to read it. Thanks again Lets...

    BMS setup

    "It made reference to B+ and P- connection points and the thing had only B- and P-" Actually reading a post and not being patronising in a reply,how hard can that be?

    BMS setup

    I know you will scream for more info but this is why I am here I bought a 36v 10ah headway pack and it came with a bms http://shop.i-tecc.de/bms-pcb-pcm/bms-12s-36v/bms-lifepo-12s-25a-36v.html the documentation for the BMS sucked so badly. It made reference to B+ and P- connection points and...

    Headway Pack Builders thread

    After reading this thread I can see my questions are quite rudimentary. But I see this is the best place to ask. I am putting together a 36V 10ah Headway pack for my skateboard. I have 12 cells and bought all the connectors and the BMS , charger etc etc. The battery space I have to work with...
