Side note, we received custom tubes for the first frames batch, so production of the first 12 frames will begin now.
Thanks Adam. This is the kind of update i thought of. Keep the customers up to date and they will understand what happens and they will be more likely wait.

Re: LMX 64 : Freeride Ebike with dual drive and torque sensor

Thanks Vasili. Thought the same thing. There is just not enough room for electronics if you use something like a hollowtech axle which is (hence the name) hollow and has a maximum large diameter and other bearings. Let's hope the axle will not bend and the cranks not break. Btw: has someone a source...

@Adam: Will you update this thread about SHIPPING DATES and stuff? Or how are customers (like me) informed of the progress. You webpage claims that the product is "in stock" and "ready to ship", which for sure is not the case (as you claimed in the opening post). You may need to change that, so othe...

Re: Charging amps through JST balance wires

NOTHING compared to something like a BC168 or UN-A6 (which i prefer more) What makes UN-A6 better? You just mean the old original? I don't know what you mean by "old original", a what you call a new one ;) I also can't say if they pulse or not, it's jus that i prefer the un-a6+ over my bc168 becaus...

Re: Charging amps through JST balance wires

You're assumptions are correct, but you shouldn't mix up BALANCE current and DISCHARGE current. Those are two different things. "Discharging" as well as "charging" as such always happen through the MAIN leads (with chargers like the Q6). Balancing is done through the balance wires. The BC168 doesn't...

Re: LMX 64 : Freeride Ebike with dual drive and torque sensor

You are right. Taper square is last century tech and really not up to date. I searched a lot for alternatives but there aren't any. The problem i see is, that hollowtech has a hollow axle (hence the name), so there is no space for electronics inside. In case someone brings a torque sensing BB to the...

Re: Charging amps through JST balance wires

It depends 8) For regular charging you will be faster with the Q6 as it can charge up to 6s with 14A = 300W. The BC168 will charge therotically at up to 8A, but for connector's safety I would stay below 3A. Still a great current to balance charge multiple packs, but for charging 30Ah batteries ... N...

Re: Charging amps through JST balance wires

The Q6 only discharges at a VERY slow rate. I thought it was gonna be a much more effective product. If there is a gap in cells then youll have to wait for a long time to dischage before charging them again I wouldn't call it ineffective. It's just that stored energy is converted to heat by little ...

Re: Charging amps through JST balance wires

Wouldnt it be easier to just patiently wait for the final cell to charge/balance rather then having to discharge 4 cells? For sure, but this is not how they work. It's easier to open a transitor gate that is connected to a little resistor and let it burn all the energy that is too much. Redistribut...

No. That's not what he's talking about. :) Believe me. We had a longer personal discussion about it. IF you have such a switch (which WILL be found at close inspection) and this switch will enable higher power modes then you're busted. And even if you don't have a switch and the setup menu of your c...

Re: Charging amps through JST balance wires

Balancing a heavily disbalanced pack with a charger like the Q6 can take forever. I will NOT charge the low cells until it pulls down the high cells down to a reasonable level. The it charges ALL cells again. As the one low cell is somehow worse than the other (lower capacity, higher internal resist...

No. That's not what he's talking about. He talks about a secret switch to activatw ANY mode that's more powerful than what's legal. So a way to hide some settings or statistical data from spying (police officer's) eyes.

Charging amps through JST balance wires

That's what EVERY charger does. It's called CC/CV. Meaning it's constant current in the beginning and near to the fully charged voltage (or whatever voltage you set for charging end) it reduces the current, more and more the nearer it gets to this voltage.

Re: Charging amps through JST balance wires

The connectors are rated for 3A. So i would say that's a safe limit for sure. I never go over that. Why? I don't know, but i don't trust those thin wires and i don't like to stress the charger itself. And most of the time it's fast enough. :) https://www.digikey.at/en/product-highlight/j/jst/xh-seri...

The hard part is making a series buss bars to handle the current in the 18650 format.
Drilling single stranded copper wire as used in home installation is how the guys building power walls do it.

Something doesn't seem right there. Even a SS41 or similar hall switch will only pull down to around 0.5v.
That's right but it was down at 0.2V after i added a voltage divider. 10k and 1k made the voltage drop to 10-20%.

Re: Building a high Amp output battery question

Also if someone could confirm this for me. at 26s the nominal voltage would be about 96, when its fully charged (HOC) would the voltage be 4v x the 26 cells in series? so something like 104v? Not ALL 18650 cells are the same, but as a rule of thumb you can calculate with 3.65V nominal on the conser...

Re: Battery supplier/builder wanted EU/UK preferably

What a shame that politicians in the EU already work on law forbidding self built batteries. Batteries will need to be approved/tested etc, so only big companies that can afford the test's costs will be able to sell batteries.
