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

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 resis...

Re: Charging amps through JST balance wires

Its taking forever for my last cell to get to 4.20. 4 cells are at 4.20 now but the last cell is at 3.88. Then the last cell (group) is defective and should be replaced. Such a huge difference in voltage means it is also different in capacity, so that cell will run out well before the others do, sh...

Re: 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. I see... Its taking forever for my last ce...

Re: Charging amps through JST balance wires

I have three of these chargers and they do NOT charge through the balance leads. They won't even work unless the balance leads and the main power lead are hooked up properly. Is it normal for Q6 to decrease its charging amps as it gets close to full battery capacity? I set mine at 2A but its only p...

Ah ok thx for that...so charging at high amps should be fine if the battery can handle it

Re: Charging amps through JST balance wires

Is that charger designed to charge that way? BC168 apparently goes to 8A, but it's pulsing, lots less heat buildup vs CC/CV. Many users say 4-6A is OK but must vary by batt model? others re-solder heavier wires too. Here is a product link...i dont need to charge up to 14A but Id like at least up to...

Charging amps through JST balance wires

Hi guys Im trying to charge/balance my battery packs with ISDT Q6 pro. I read that 1A is a safe amount of charge that is recommended to go through balance wires. The Q6 goes up to 14A. I have the input connected to the wall socket and the main battery leads are connected to the output of the Q6 alon...

I would just go with a cellog style meter and balancer. Simple. Now how to find a good one ? AS I have 5 of Them 3 different styles. All cheap but do work. Not the two hyperions. bad. To easy to back charger on the road.
I see...in your opinion..which model would be the most accurate?

Re: What would the smallest possible battery to power this?

Would a portable battery bank for smartphones work? I could cut the end of a usb cable and attach an xt60 Yes - BUT - to get to output 7 volts it has to be a QC 3.0 supply and you have to spoof it with a little controller. Not the easiest thing to do. But elegant. But isnt 7V the minimum input volt...

Re: What would the smallest possible battery to power this?

Says it needs minimum 7V, so a 3S 18650 pack of whatever is around should work fine. Even 2S should work, though it might shut off before they're empty. Wouldn't it be easier to just carry a celllog or something similar instead? Would probably cost about the same as the battery you need. Hi I do ha...

Would anyone have info on this huge cell?

Im in Korea and its made by LG. The seller didnt give any specs on them..only that they are for industrial use. Voltage is at the standard 3.6V and a 10 or 20 cell pack would be quite size and weight. I think the seller told me that they are 42Ah..wow Would these be considered pouch cells? https://i...

Re: new cyclone 3000 w mid-drive kit?

Hi guys
What is the maximum voltage you are running with the stock controller that came with the cyclone?
Rated 36-72V, but wondering if anyone has pushed it beyond 72V??

My controller is rate 72v but caps are 100v, so..

is it possible to build my battery above 72v but stay under 100v so that I dont blow the controller? For example, a 22s battery pack which would be about 92V on a full charge or a bit lower at 84v? But 92v would be better :wink:
Thanks

leafbike 1500w beats it in efficiency at lower power levels ( 1000-1600W ). At higher power levels ( >1600W ), the MXUS wins the efficiency/power contest, of course. MXUS 5kw motor is one i don't have a dyno graph for, but i'd pick it over a QS any day for a larger motor because of how damn heavy t...

You just connect it through the main big leads, and set the charger to 1S. The JSTs are for balancing, nothing to balance charging a single cell.
Ok i see thanks!

You could connect the low cell individually, and charge it as a 1S. That would be the fastest way to get it close to the other cells so you can more quickly perform the balance charge.
But the imax b6 charges from 2 to 6 cells according to the JST connectors

Re: Problem with my B6 Imax charger

all balance chargers do that, if the 4 cells are already at 4.20 volts, the charger reduces amps until the weak cell catches up. This can take all day or several days.
