Out of date videos are often misleading, especially on YouTube. I always look at the date before viewing. Responsible authors would take them down if they later prove to be misleading or inaccurate.

I tried "turning the Phone sideways " - that works !!

The company, Global power Co LT Store of China has agreed to send a free replacement.

No, I understand that's not a good idea. I already had it on the charger at 3.2 volts and around half an amp, but the charger gave up as described above. So now i think i shall give up on this one cell... Everyday now there seem to be new revelations about these batteries and even conflicting...

Yes, I noticed the "corrosion" which hasn't occurred on any other of my 24 cells (other set ups) ... Could some chemical have come out of that cell to cause it ? They are only six months old. Daly BMS supposed to be for LIPO4. Busbars supposed to be tinned copper and came with the cells. They...

All rather flimsy plastic at the moment - lid and box. Seems to have blown out (upwards), through the blue cover and also through the transparent thin plastic just above that. Little specks of blue on the nearby terminal, looking like typical aluminium corrosion. I have replaced that one cell...

Thanks for advice !

Charging with two 100 watt panels (just moved into full sun) and giving 30 to 40 volts and a maximum of 5.9 amps at midday. Most of the cells are slightly bloated.

I always have the "rotation lock" on, because my phone switches continually between landscape mode and back again and you can't read a thing! Snoobler put me on to this in one of his other posts... some people have all the answers !!

Mr D J Smiley Send me a couple of thousand dollars and I will buy those things you recommend... Despite the "Avatar" I am actually a 77 yesr old pensioner living on $1000 a month !!

I have also had problems with the cells (of course !) and am currently in process of replacing three due to bloating, over high voltage and runaway charging... The BMS saga is a whole other story and I have tried JBL, Heyo and various Daly ones - none very impressive... frankly the cells...

Superb explanation ! I almost understand the whole process! Up to now they have just been Capital Letters (acronyms) ! Thanks.

Ok, thanks...that clears that up then. The actual car battery is only a 60 a/hr lead acid, so I was thinking....

No... I've never seen a "block" like that to click on...

LiFePo4

Maybe I should put it back in a "pack" and hope its fellow cells help it to recover?

Thanks, guys, I should really know all this......:oops:

Yes, homebuilt battery, then wanted to change the cells. So disconnected all wiring except the BMS sensor wires and left it for a few days waiting for the new batteries to arrive. When I got back with the new batteries I was horrified to find all the cells right down and this particular one at...

Working on the laptop...must be just not available on the phone.

Looking for it... but not found. Maybe only on Desktop?

Just not available. Period.! I got it all on the laptop though! Thanks!

Exactly. But I was dealing with someone with very poor English skills and who only seemed to know how to send .pdf files !!!

I'll have to try on my old laptop. Thanks for the tip anyway.

I have two sets of 24v 90A/hr batteries, one old, one new, and want to connect them in parallel. Should I connect the negative to the second battery B- or to the P- ? And does it make a big difference ? Will each battery's BMS take care of its own and not interfere with the second battery...

Thanks for that - I see lots of advantages for using MPPT in future... for the present I am stuck with PWM and wonder, given the panel and inverter data above, how many 300 watt panels to connect (in parallel). 4 should be OK in theory (36 amps max) but maybe 2 or 3 would be wiser to start...

Interesting theory, a bit too Agatha Christie like to me, as these cells have been in their own box since new, about six months ago. And situated in a remote cabin in the middle of North Borneo ! But accidents do happen of course and there certainly are a lot of curious creatures here (even...

This from the inverter/charger manual.

Yes, most cells Yes, most cells are slightly bloated, in common with the other 20 cells I currently have... BMS cut offs 3.65 max, 2.6 min. Controller same as I use on my primary cabin not far away. Indicates 30 to 40 volts input to battery and 5.9 amps max at midday. That's the output to...

Thanks for your input... You're probably right and the BMS wouldn't like a 0 volt return from 4 of its wires... IF it is monitoring total voltage. It is a very basic BMS (e-bike type) and seems to only react to over and low voltage... there's no monitoring function to see what it's doing, (I...

I'll soon be building a much larger battery (when I've finally got all the ingredients together from China!) - 2P8S. Watch this space for more possible problems !!
