they are welded 6mm studs - soon will finish on Cell 7 and start Cell 8 tomorrow last one - so far they all gave over 230ah not by much but consider that i didnt go down to 2.5V - i stop at 2.9V going down to 2.5v may have got a few more AH - could be 5ah more or a bit less - i am...

i think so - i been buying these things for the past decade and these i have to say are the first ones that i got the full Cap. no dents or bloat or anything that looks bad - wrapping it perfect - besides headways when i first started are great cells - those were brand new top notch and i...

yes i did notice that BAD - i though that was funny also - not all have BAD - they all check out fine with the Code Checker - and all are giving me 230ah - i got some as high as 234ah - the lowest 231 and change - this is from 2.9v to 3.6v - i am not stressing it - these have been the best...

I also got 8 CALB Cells from Docan - 230ah models and on my 7th cell testing for Cap. so far they all gave over 230ah - they look mint excellent condition - i am happy so far also - having them here in the US - i got them in 5 days - i am also glad i got them over the EVE cells i was...

i seen photos and did a video chat with amy - shes nice - but really cant say with a photo alone - i am sure it be fine and have M6 stud welded - i just wanted to double check - one time long ago i needed a replacement cell - they were 100ah cells - i ordered one - and i get it with a M4...

i see - in my case i wont be pulling 1C if its a 230ah cell - i should be fine then with either A or B cells ? but alot of users here swear by getting A cells from a seller who does alot of sales on here - is it to be believed or who knows -

I just purchased a 600 watt dump load diverter - it will be used to just discharge a large battery - but i am not sure which side is the Pos and Neg ? it has two ends - one on each side to connect the wire to - but no markings as to which is Pos or Neg. how can i know ? i am going...

Ok we figured it out - forget those apps on the cell phone - they are not always accurate as in my case it was way off and wrong - global power has a code checker - but it didnt work for me - so i got concerned - well it turns out - it was the browser Firefox - not alot of sites work...

here

power wheelchair no BMS used -

how can i get in touch with this Luyuan for cells ?

Docan power is not Grade A ?

why would you say that

been using lithium this way for almost a decade now - work great - for my use -

the scanner app does work - thats what i used - you have to add the bottom line first - which are all the same - the top row are different - try it again - the only thing is my cells were all produced about a year ago - other than that - they are excellent - who knows if they sat at CALB...

thanks for that i will check them out - and yes i been using a Cellpro charger PL 8 - still do - does a great job - fast and simple i also started with the headways - those are going on 8 years now - lost some cap. but still great - need to do a upgrade to new cells with over double...

Has anyone purchased these cells - can you tell me for sure they are M6 size studs welded on top ? its confusing with there buss bars that say M4 - i am trying to explain to them what i mean - but its not working - i dont want to receive them with a M4 stud on top thats too small - i...

thanks thats the app i used - the scanner app on my phone - the thing is - it dosnt work if you scan it - you have to enter it manually - at first i was concerned when it didnt work - then i found out its not the same as QR code to scan - CALB do it different - i tried it again after it...

thank you - its a great charger fast simple balances on the nose - never over charges - what does LFP stand for ?

Its too bad no BMS can do as good a job - i wonder why cant they make a BMS better - they are very slow and lacking - but then i dont know for solar stuff -

yes bottom line first - its the same on all cells - the top line is the difference - i checked them all - they all show as a valid code - all show its CALB LF230 - i feel totally fine with them - no reason to think otherwise - i would get CALB again if or when i need more cells - but i think...

they no longer make the PL 8 which sucks - nothing else out there as good - next best would have to be the Icharger - not as good i believe but not many other options - you need a decent PSU for it -

someone else should just copy the PL 8 and make a new charger - that would be great - all i know is using one does an excellent job - fast simple and perfect balance - the first step is getting matched cells which is harder to find than you would think - i am considering docan power for...

i though everyone on here was more or less using Docan Power as there main source for quality cells - reason i came here to find out more since you guys here seem to use alot of cells -

Hi - have you had issues with Docan and Jenny ? i want to order some also - but dont want issues - if they are not up to spec i want an exchange of Cell - this worries me

i never had an issue so far - i dont use buss bars - i do use cables instead - and use a sheet of silicone in between each cell - and do use nylocks for the screws - i learned as i went along - making mistakes of course and redoing better each time - buss bars would make it easier to make...

yes i agree - if they are not what they are stated to be - then it should be known - if its Grade B - then say it and charge less thats all - if it says GRADE A + what ever that means - it should not be bloated - and should give the full Cap. - i am looking around for cells also at the...

i just received some CALB Cells - curious to see what the QR code says - or maybe i dont want to see it - haha it dosnt seem to work - or i am doing something wrong - has anyone decoded a CALB Cell ? if so -what did you use - and how did you do it - i have two sets of numbers -...

yes thats a big deal - is the size - 230ah cells are the max that can fit and those are what i am shooting for - 8S 24V
