Finaly I have found an answer to my question. OCRC_EN OCC self-recovery 0: Disable over-current self-recovery enable 1: Enable over-current self-recovery enable

Just ordered at Alibaba mentioned above CATL cells with studs welded. I will try to make some review on them as soon as I get them in Russia. Initially wanted EVE 280 but it lookes like they are out of stock at many stores or available at higger prices or more expensive shipping to my place.

I had no luck to order from them, and it was a second try. Several days ago contacted them on Alibaba, made an inquiry for 4pcs LISHEN 280 since they did not have EVE. Negotiated details. Placed order accordingly, then contacted Aimee to approve, so far no aproval for several days. Afterall made...

Upgraded 25A dcdc from Aliexpress with fan and thermostat

Hello Browneye, Today after some more tests I figured out that it takes 5 minutes for Xtra N to return back to boost mode once the voltage drops to 'boost reconnect voltage'. So this process is not immediate. I even increased boot reconnect voltage to start this process faster, but same result -...

Thats interesting experience. Im keeping eye on such qnbbm balancer. By the way, is it really working better than the one with bunch of capacitors such as Heltec? At one of the sites on AE they mention that 4S balancer: Voltage Difference vs Balance Power is 1A@300mV and 3A@1V Ive asked the...

Ok, we' ll see. The cells are now on AliExpress as well. 5885ronny - guy on youtube with catl 310 amps. His cells have qr in the middle on the top lead.

Greetings! I have a 4s Deligreen 100a BMS and want to install reset button for 2pin plug. Do I understand right that the cirrect type of connector is JST 2.0 PH?

I assume phone numbers are written on the package, very strange why they dont call to re-confirm the address. Actually have no experience with UPS, but I think it is not the cheapest servirce.

Browneye, Thanks a lot for a feedback. I have this solar system for my camper truck. Use it occasionally for going out. System is lifepo4 310ah 12v, Xtra N 30A, and 2*200w Sunpower custom 30 cell foldable panels in series, but for this particular test I used 1 200w foldable panel from AE. BMS is...

I agree with such approach especially when it refers to automotive parts. But if I take my system- everything goes directly from China- cells, solar pannels, wires, terminals, epsolar mppt, bms, ballancer, dc compressor freezer. I reviewed the dc chargers from the first page. They actually have...

Hey guys! Has anybody bused this charger from AE? Im waiting for my cells and later on want from time to time charge lifepo4 from truck alternater/starter battery https://a.aliexpress.com/_985xE6

When I started using this dcdc charger I had issues with heating after maybe 10minutes. With 25A current it gets hot very quickly. The list of parts 80mm fan with dgbb https://aliexpress.ru/item/1005002710797854.html Grill for fan I purchased at local store. Sensor and relay witch programming...

No problem with manual switch since I dont want to have my LIFEPo4 always connected to starter battery. Generally I have an old Toyota 199x truck used for camping. Portable solar pannels and mppt. And dc compressor freezer. This system has been working for me for several years. Now want to use...

Hello. I have Smart BMS v. 2.1.7 Android. Im just curious how to reload it again once overcurrent protection has triggered. Charge MOS and Discharge MOS tabs are gray on the main screen and manually making them on and off on Sytem tab does not help. So far I have found only "System reboot" in...

This is just tests. I have 100A BMS and 80A manul rotection. My angle grinder has drawn something about 85A, so BMS triggered.

You are right regarding charging voltage - its all ok. My task is just to limit charge current and not overload alternator and wires since without any box low soc LIFEPo4 would draw too much current. In my case with 310ah battery it took more than 70A. I guess it could take more but i had bms...

I have 500W AG and 1500W Epever inverter for lifepo4 which I normally use with this system and for tests Ive plugged 1100W AG. It started ok and worked for some time but when I made more load on disk the current inreased more than 80Amps and bms triggered. So thats why Im curios how to reset it...

Yes, agree. Not so good... Probably can be used only if not charged to soc 100%. But BMS should disconnect then if it finds overvoltage cell than. One if the tasks for me is not to overload alternator, since the model is from 1990s without any computer on board.

if not using dc-dc, the LFP would draw too much current from the sourse (alternator or lead acid). I had my BMS tuned to disconnect when current exceeds 60Amps. I did tests and on half discharged LFP it was over this figure (60A) and the trigger disconnected the sourse. So I decided to order...

Here is a dumb unregulated version with upper limit of 14.5V that Ive found onAE https://a.aliexpress.com/_AnBp6E

My understanding is that it is a new product for most of us and still besides guessings an rumours we almost know nothing about those cells. Only few minor tests have been made. Probably same was with eve and lishen some time ago. Im still waiting for my 310A cells, they are at Horgos customs...

Thank you, makes sense to me too✌️ I'll try to contact manufacturer for this device, maybe voltage could be fixed to no more 14.6. if not than consider another dc-dc charger, maybe more or less budget ones are available. Upd checked sticker on their charger - it says 14.6~14.8 +/-0.2%

One week ago I ordered 4 310ah cells through Alibaba with delivery to Russia. Ive talked with Kim, quick response and answered all my questions. Asked also to film my cells before delivery. They did with tests.

From their website: Contemporary Amperex Technology Co., Limited (CATL) is a global leader in the development and manufacturing of lithium-ion batteries, with businesses covering R&D, manufacturing and sales in battery systems for new energy vehicles and energy storage systems. in wiki it is...

Ok, thanks! Would get one on Aliexpress as it is cheaper and faster option for my place

Hello Friends! Can somebody explain me how XTRA/Tracer works with 'boost' settings. I have the following settings, attached. With boost 14.2; boost reconnect 13.3, boost dur 10min; and float chg 13.6. Once I power on XTRA N it keeps charging untill 14.2 and rests there for 10min. Than float is...

Thats true, only from supplier then. I'm curious if there were cases on the forum where someone got support euther from EVE or Lishen directly for the cells that were purchased on Alibaba or Xpress? On youtube im tracking the guy from Germany who purchase such, few tests are made still. Maybe...

Greetings! Ive got the new BLE-01 in black box which is replacing the one in blue box. The problem is that I cant see the signal from it on any of my Samsung Galaxy S5 and S7. So it is not epever software issue but rather phisical connection problem. After communication with epever support Ive...
