How many VPC would give you a 100% SOC on a 15S or does it not work like that.

I don't have the user manual for it and can't find anything for it online. May i ask what the Bulk value is in your manual. Found the following BMS software for Leoch. Would i be able to get any certain values of it that could help me out. https://drive.google.com/file/d/1BBnAYRHpGbXI9p2eVA3JUldGf4QvfL9X/view

I changed the Battery cables last night, but still only charged to 70%. I know someone else who has the same batteries (x2) running on his MKS 5kW and asked him to check the cells on his and both of his have 15. His do charge to full though !! Decided to go through the manual again last night and i saw it says the Min battery bank size should be 170AH, I've got 100Ah. Could this be a causing a problem at all. I did read a post about making the Bulk and the Float the same values - Is it worth trying this ? If none of the above are the problem would connecting a separate smart charger to the battery help get it up to 100% as it seems the inverter is stopping the charge when its getting to 70%SOC or do i just have the wrong settings on 26, 27 and 29.

Hi Coulomb. Is this the charging LED (middle of the 3) or something on the battery itself? -YES, The charging light on the inverter stays solid saying the battery is fully charged but the SOC lights on the battery itself only has 3 of the 4 lights on and if i go into the menu on the battery it says its at 70% charge. I can try change the battery cable and see if that helps. I'll also have a look this evening to see what happens with the battery icon when it stops charging. I can also open it up and see if there is actually 15 or 16 cells. Should i change settings 26, 27 and 29 to something else and if so any ideas ? What voltage should each cell be if the battery is fully charged? I'm really stuck on this and not too sure what else i can do. http://www.leoch.com/pdf/reserve-power/Lithium/LFeLi-48100C.pdf I have the one with the screen on it (48100CB)

Hi guys. I'm new to the forum but have been reading a lot of posts from here to try figure out whats happening with my inverter and really hoping someone can help me out. I have the Axpert MKSII 5kW inverter that i purchased from Full Circle Solar in Jhb.It says the main CPU version is 71.50 and it was manufactured in April 2019. I set it up this weekend but not running any panels at the moment as i am waiting for them to arrive. So the battery is charging off utility when we get it and just running the Tv , lights, Decoder, Wifi and a few small other items, max load i use is 500W for now. The problem i have is it is only charging the battery to 70% SOC according to the BMS on the battery pack. (I have a Leoch 48100CB LFeLi, I didn't purchase this battery. It was given to me by someone who left the country as i live in Zim) The screen on the battery was showing the pack Voltage at 49.77V , the SOC at 68.89% and cell voltages at 3318mV (it has 15 cells) and 3 SOC lights where on. The inverter was saying it was 49.6V and was showing two bars on the battery. I have tried different voltages for bulk and float (settings 26 & 27) but when it gets to 70% it stops charging the battery, The charging light stays solid and the battery says its discharging. These are the settings i have at the moment 01 - SBU 02 - 50A 03-UPS 04 - SDS 05 - USE 06 - LRE 07 - TRE 09 - 50Hz 11 - 50A 12 - 48V (dont think this matters without having panels) 13 - 51V (same as 12) 16 - CUT 18 - BON 19 - ESP 20 - LON 22 - AON 23 - BYD 25 - FEN 26 - 53.5V 27 - 52.7V 29 - 47V 31 - SBD 32 - AUT 33 - EDS When it is charging the battery it says it is charging it at 21A but i have it set to 50A, is it suppose to charge at that. Any info on what i need to change or do to get it to charge the battery fully would be much appreciated.
