0.6 amps is the max for this JK BMS.
Regardless I have gotten it to balance within the limit set in the config for the BMS.
Why is it questionable that cell 5 has an issue? Clearly it is the only one under performing here right?
From my perspective it matters in terms of getting what you pay for and what's advertised.
If one wants B, they can get B (hope you don't get C grade) and if one wants A they should get A and not something else.
Yes I'm thanking them for alerting me of the the negative experiences so that I can be wiser. Hence this post and I'm trying my best to get the best deal. If there is something I can push Docan or anyone to help me ensure I don't get scammed/ripped of.
No trolling here.
Zhang on FB Marketplace.
But I think they live in China. They are confusing because sounds like they would ship from Houston warehouse but then says will ship from China.
I'm probably done talking with them, I've learned more and would probably just order from Ezeal
Yeah I'm looking around to try and find something to suite me, but all the All in one inverters I find seem to require > 120 VOC which I'm not looking to do atm with just two panels.
Looking for separate parts but trying to make sense of MPPT Charge Controllers + Inverters. This will also be...
No laws are broken either federal or in the state of Georgia or in the state of Texas. I am a participant in the conversation, therefore I can legally record it
I will be doing that part in a similar fashion. But how do you go from the combiner box to the inverter with a 6AWG wire when both are designed for connection with an MC4 connector?
EDIT: Ok after looking at my inverter and the combiner box output I see it just has terminals and does not expect...
I just don't get Alibaba yet. I don't know what to trust and it's really hard to communicate with them. Yes, you absolutely right There would be a huge markup likely
So if my Inverter has no grounding aside from the ground for AC Input/output, then my EGC wire will go from the panels to PV Combiner box and then one ground wire from PV Combiner Box all the way to the houses Ground Bus bar? If so thats about 80 feet from the PV Combiner Box to Houses Ground...
Video details what I have to work with.

Inverter/Hybrid: SPF 3000 TL LVM-48P
6AWG Wire about 100 feet to get from combiner box (outside) to inverter inside), not detailed in video.
Mount will be...
Picture proof is picture proof. If you can prove it and they know they did the fraud lets see what kind of fight they can put up.
Unless the counterfeit by now how gotten really good and hard to prove.
Yes rest of the equipment meaning my hybrid inverter, battery and ground rod are all located near each other, just the panels and the PV Combiner box are about 80 feet (PV Combiner box) and another 20 feet to panels.
Top balance was with the JK BMS active balancer, last time I did it I let it do it till it decided it could balance no more based on the threshold I had set. I've done no discharge test, I don't think I have the equipment to do that.
Got all my panels mounted. Going to be wiring a copper wire between them to ground them.
But when it comes to the battery, it seems I need 1 * 4 AWG wire but I can't find that right now.
Can I safely use two 6AWG battery wires per pole instead?
I also have only one 70AMP fuse and it says max...
And what are folks doing to measure/know if the applied compression force is within spec?
In my case my battery states 3000N to 7000N and I think it even details/hints something about that changing as the batteries age...
If 3.1 and below they start to get uneven, then I should configure the BMS for low voltage cut off at 3.1? Or maybe the inverter? The way its setup up right now I basically have it cut out / bottom at at like their rated min voltage of 2.5 ~ 2.65
So my EVE 304AH batteries from 18650 battery company in Georgia just came to my house.
I'm doing some testing and I'm getting 6.0 mega ohms of resistance?
This seems way off yes?
Not really, unless you're picking up directly from there.
I purchased from them and when you take into account shipping and taxes (and I live in Texas) it cost me still around $1,500.
I think i can still technically return through them, but they have a 40% restock fee I'm trying to avoid.
So...
Really curious how long it will take them to ship one item purchase...
OK it arrived last week, just checked the mail. Was thrown off since it still says awaiting shipment.
I might contact them and say every 3 months
I can get that, balance like I did last time and then just run a load with the shunt to test?
This right here right? https://www.amazon.com/Victron-Energy-SmartShunt-Battery-Bluetooth/dp/B0856PHNLX?th=1
Then with the data I can go to...
I have the same PV Combiner box as shown in this video.
The slot circled green in this image I've uploaded is the ground. I don't see him doing anything with it?
Is that where I attach a wire going form the green out the green circle and to a 8 foot grounding rod?
And am I correctly...
Seems cheaper to buy two 30V max 10 amp max DC chargers. I guess I could use both to each charge 8s? Would cut the charge time in half right? 1 Week instead of 2 weeks?
The BMS I have has only a 0.6 amp active balancer so that will be really slow to strictly depend on for balancing.
This is just for me to learn and charge my tesla via a slow charger daily, whatever the system can give it.

I think I get it but not sure.
Does a bypass diode activate once the PV cells in series produce voltage that is too low?
If so what is that threshold?
And if that treshold varies per panel how can I learn to read a spec sheet to understand that so I can get an idea for what shading is too much...
Hoa wouldn't let me build a water collector large enough and my yard probably isn't big enough for the amount id have to keep and store.
AWG let's you use the air as storage.
Also talking with a local Docan Power distributor.
Any questions you guys can think of I should ask to have some peace of mind or is it pretty much buy and find out?
I guess I could try buying just one and see?
Dead meaning it will never charge again or dead meaning its safe 0% SOC?
I think the spec sheet says it can go to 2.5 but I obviously don't want to go that low ever.
