Will, I'm not trying to pick a fight here, but you hardly have a voice / knowledge in this.
You charge your cells on daily basis to full.
Nothing wrong with that.
On the other hand, you advertise how people can get almost double the cycle count by not charge them 100% bit use 10-90% as charge space.
This effectively stops top balance.
You have no experience in how dis affects the imbalance, or even tried how a Daly 0.08A (total, not per cell) can balance the pack when you decide to charge full again.
We talked few times PM about this.
Easy to write that you don't understand the need for active balancer, if you don't want to use it.
For most of the post of supervstech, I agree with him.
His word choice that there is ZERO reason to make wires like this is dumb., Feels like easy score without knowing what he talks about.
And that part, I try to make him see the error of that.
Unless he knows an wireless way of making 4 contact per cell, 75cm or better 3 meter per cell, will look messy.
Not unsafe.
I did not order 30 meter coating to bundle the 4 wires nice together.
Local stores don't have it.
Visual it would have made it look more nice, for safety.. no difference.
Yes!
Nut on a nut!
And with absolute good reason.
You can try to bash me how that is a bad contact and bla bla bla.
Yet, measure Voltage on the studs is normal..
High resistance?
Nope. Higher then copper.
True.
Not high resistance.
I'm not trying to push-pull 100A.
Maximal 1.5A per cell.
5 watt.
Really??
Have you tried it?
Place a stainless steel stud between 2 wires and "blast" 5 whole watts via it?
Where you able to measure a thenth it a less temperature increase??
Please. Stay realistic.
Why I didn't not share this information sooner.
For this type of discussion.
Get realistic.
Look at your 12v (not 3.2v) 300w (not 5!) and see stainless steel bolts and studs as main contact to your sigaret lighter....
Apparently I'm the only one who has troubles with th strength of the grubscrew in the cells.
Making it a mandatory one time mount.
Having long enough grubscrew, to be able to add the BMS wires AFTER you installed the bus-bar is a really good way of working.
We "all" know BMS mostly don't live the lifetime of the LiFePO4 cells.
Especially the China ones.
I know at least 10 forum members who have one or more BMS mounts.
We are talking about sensing the voltage. That's what we do.
With my high sensitive battery meter I could not measure Voltage difference between the top of the stainless stud and the aluminium terminal.
We talk about 0.000x voltage
That sensitive.
Sure if you have more sensitive, there eventually will be difference.
I still need to see the BMS that uses 0.0001v as a significant number.
So please.
Stay realistic people.
In Dutch we call this " op alle slakken zout leggen" or
"spijkers op laag water zoeken" or
"Mieren neuken"
I don't know the English equivalent.
If this is the direction it needs to go.
Please close this thread for further discussion.
Exactly this is why many people don't share their failure.
@Will..
Once again.
Please, if you want to have any right of talking about active balancer and charging 10-90% ...
Do it!!!
And see how the nice Daly does not work getting the pack back in balance after 3 months.
2 sets.
One with and without active balancer, both Daly BMS 0.08A balance per setup
Then talk about how it does or doesn't make a difference.
Without it, it's just your personal preference, based on a failure of not connect a wiree that you Blaim to be the fault of the Balancer as no BMS would have a probelm with a lose wire.
That's right. It's not a BMS...
You last video as far as I remember about active balancer who you first thought worked fine..
Thousands of YouTube video show they do, unless you mess up..
Disconnect one wire
You know a lot, not this (active balancer) field, please educate and work with it before you make a statement.
