Endless Sphere

Tool batteries charge at successfully at very high rates. Makita 18V chargers charge at 9 amp maximum. Their secret is good engineering and design. no, they use low capacity high current cells with short cycle life. not high capacity cells with high cycle life like you see in automotive or laptop u...

Got my kWeld yesterday and got it all together, just waiting on the power source now. For the power source, I ordered two Turnigy Nano-tech 5000mAh batteries, with the intent to run them in parallel to reduce the 'abuse' on each battery, but I've read what seem to be conflicting information. I've r...

still 7 bucks in europe...

i used it with a set of 4 60Ah thundersky/winston cells that i used for years in my previous car and it faulted out as the amps was WELL above 2000.

so, dont use those.

just go to the support page, fany will probably answer.

email fany, explain the current state of the unit and ask if a firmware fix would help. if possible they will send you the correct file.

if you have brand new cells fully charged you might get pretty serious amps. that will reduce after a few cycles or just discharge the pack to 4v per cel or something.

technically you could just set the wire length to 1m or so so it does not error out. but you will probably blow the arse out of the diodes if you use it like that. best is to change the supply side so you stay within spec.

Communicating with QS is fairly challenging

depends on how many motors you order...

that said, they are are a fuckton better then sevcon for example. they wont even respond a email unless you order a pallet of the things.

they are exactly the same thing as a "normal" lipo charger except its not written on the box. Only up to the point of full charge, yes. But a lot of chargers (for example, hobby balance chargers, et al) stop the charge action at a programmed point. They don't continue to apply voltage to the pack w...

the kweld is superior, no question but there is a price for it, litteraly. if you do this hobby wise and dont do "heavy duty" work or pro level battery building i would just buy a malectrics as it only needs a simple 12v SLA battery to drive it and you can repair it yourself if you blow up the mosfe...

Are you saying these are proper chargers rather than plain PSUs? Terminate charge automatically when the battery is Full? a (lithium) battery is " full" when you reach the set voltage and the battery does not take anymore current. it is -that- simple. that some chargers have a little extra componen...

or just buy a proper CC/CV mean well from the ELC or HLC line or better yet: the HRP/HRPG line wich are medical grade.

Translation: Is it possible to use this Adaptto "charging coil" with other controllers, or is it designed so that it only works with theirs? in your opinion you can use the charging coil with all the controller or you have to go through the adapter controller http://adaptto.com/Products/Charging-Co...

what is your indication why the 30Q suck so much?
spec sheet wise it should behave better.

automatic is just for lazy people.

but FE-36 is nice stuff. i still got old style halon in my car and kitchen.

Plus the safety concerns flippy expressed. https://www.aliexpress.com/item/4000743682041.html or https://www.aliexpress.com/item/4000782479393.html eiter should be mandatory if you plan on doing something if you dont know if those cells can even take the "fast" charging currents while being confine...

Have not seen formal testing to support either way.

my testing shows that most cells increase in capacity a few percent after the first few charges but lose them pretty much a few cycles later.

its temperature in this case.
using a battery like that for cranking a car causes the battery to heat up, and that lowers the IR wich improves performance.

Yes can find the store no problem, but not the charger (PSU), deleted the app still no go.

Never mind could be my setup,

dont use the app, just use your pc.

No go, maybe their website tech team stayed home

the malectrics welder will not survive supercaps. do not do this. go to your local car parts store and buy the cheapest 40Ah battery and use that. and get something to charge the battery if you dont have a power supply that can put out 14V. the capacitor unit from kweld is matched to the kweld wich ...

Or narrow down to one cell and focus in what is the best we can get with it

this is why my go-to is the samsung 29E and the panasonic PF. they hold the balance between lifepspan, power and price.
