that guy wesnewell is always stalking me and every time i post up something he makes some insulting and snide remark because i called him out on how ignorant he is about how a BMS works and how he demands that the LVC for lipo has to be 3.65V because he says so. he knows nothing about lipo chemistry and just made up this idea that the LVC has to be 3.65V because he said so.
he is just a bully and totally ignorant of how a BMS works. he has never had a BMS to examine, does not know how they work and could not even tell you how they do what they do. so a picture would not make any difference because he would not know what he is looking at.
he gets away with stalking me here because the insiders who run this place do not enforce the rules against threatening violence or harassment when people do it to me but when i try to respond to protect myself then the insiders delete my posts because i am not one of them.
just the way this place works.
i see that Bestechpower has a new 13S lipo BMS i will add to my order to see how it works but not sure of the cost yet, it does have the metal heat sink on top:

dnmun said:you can open the BMS yourself and look. i posted a picture, there is no balancing network. the surface mount parts for the balancing network were not included when the placement machine was programmed.
So you think that picture is good enough huh. If that's the quality of your work, I think I'll pass.dnmun said:nope, that picture is good enuff.

I tried making a bulb discharger but they almost caught on fire.

the cali pack will go down to 37v. most people have lvc shutoff in controller that stops at 41v. please lover the lvc on your controller to get 15ah

999zip999 said:I'm with Wesnewell why would someone build a bms without a balance circuit ? Plus I can't type how would I read a bms board. I would put an extra set of sense wires, like my old ping and check with a cellog. Cuz that's the way I like it.

My pack started cutting out at 45v....i can't get a full capacity test because my battery keeps cutting out and the meter keeps wattsup keeps resetting...something is wrong with my pack. I made it 28 miles before it started cutting out @ 46v, and any heavy throttle over 10 amps would cut out the battery...towards the end of my ride the vlow was hitting 38v under throttle, unfortunately my chain got caught under the chainring so i couldn't finish the last bit.
I don't have a system or means to charge it to 36v, but based on this info i'm pretty sure there is a dead cell in this pack
What would cause the BMS to cut out at 46v? It does charge to the full 54.8v

yeah, 18 on my gng and 22 for my bbs02... This ride for instance was 31 miles @ 15mph average road/rail trail with me giving 25% effort.
When it started cutting off towards the end the battery cut off power at 46volts, resetting my watts up, then powered back on a few seconds later, then would stay on as long as i kept the amps low.
When it first happened i thought maybe it overheated but when i opened the box it was just warm
The battery was cutting off while it wasn't hitting the LVC on either the system or battery.
I'm guessing maybe there is a bad cell and the bms is tripping.
