    Felicity LPBA unbalanced cells

    Hello dears, I am importing Felicity LPBA 48V 170 Ah 16s1p LiFePo4 battery which defined to be CATL grade A cells from China. unfortunately 1 battery I installed it for my sister's house after it gets fully charged from utility for example and restrd long time on around 54v but stops charging...

    Felicity LPBA low voltage

    I monitored the battery many time, the configurations is 56.4V for float and bulk charge parameters, but no times it exceeded the range of 55V so it stops around this voltage. now I connected the Battery BMS to the monitor software on the PC, and wait until the BMS stops charging and battery...

    Felicity LPBA low voltage

    intresting information, but if the bms stops charging before the battery get fully charged, how to force it to charge and see how much the cells are balanced?

    Felicity LPBA low voltage

    thanks Bobert, I connected 3 days ago the BMS to the pc monitor and I see the 16 cells are 100% balanced with 2 digits, so all was 3.34*v. the cycles counter after 2 weeks of usage was 4 cycles only. the battery seems to give the expected energy capacity but I will do capacity test by the...

    Felicity LPBA low voltage

    Hello guys, I installed many solar systems ladt months all were Felicity inverter 5kw and Felicity LiFePo4 battery LPBA48170 which is 170Ah 51.2V, CATL grade A cells 6000 Cycles. Ihave installed 2 systems last week in the same building for 2 different apartments. i connected them to the...

    Lead acid tubular batteries status checking

    hello, the charger gives 15 point something at open and when I connected it to the battery it drops to 14.2 or 3 I think, and increase with time to limits 14.8 or 9 also I think. I called the middle east agent today and yhey asked me to carry them to the local dealer I don't know what they...

    flooded lead acid tubular batteries power efficiency factor

    hello everybody, how much we can compute the energy stored in a battery if we register the instantaneous power (charging voltage and current) over time, so for example a batteries of 200Ah takes 20 hours to be fully charged with 10A charging current. can we estimate the energy stored by...

    Lead acid tubular batteries status checking

    hello I charged the 3 batteries sometimes each one individual and sometimes 2 in parallel, currently lowest gravity is around 1.200 sometimes I read 1.175 if I flip and turn the hydrometer I see some variation in float glass position. but your are saying charge each until current drops under...

    Lead acid tubular batteries status checking

    hello, thanks for the fruitful information. ok but in my case the one the hasn't been discharged gives a voltage of 13.07V and gravity of 1.250 and that is after after connecting and charging them together in series. but the 3 others batteries are in the red region even if their voltage is...

    Lead acid tubular batteries status checking

    I knew that connect the 4 batteries in series when they are in different states of charge is a bad idea but is it such dagerous or destructive? i charged a single battery with 15A old tranformator based charged, it was already 13.07V just after disconnect the inverter so during the charging...

    Lead acid tubular batteries status checking

    welcome and thanks in advance. I freed up the all system (4860w panels) and the sunny days last week 3 days even if I saw the charging current before noon is 20A and after noon is limited to zero also even if utility is available which indicates that charging has been almost finished due to low...

    new indian tubular batteries bad performance

    Hello everybody, I have bought 4 200Ah 12V tubular flooded lead acid batteries for my 5kw hybrid solar system 3 weeks ago. Unfortunately I got bad batteries performance in term of capacity even if they are "fully charged" as the the Must inverter PH18 Plus showing on the display and user...

    Lead acid tubular batteries status checking

    Hello everybody, 6 weeks ago I installed my solar system 12 panels 405w from Trinasolar with Must hybrid inverter 5000W 48V (PH18-5048 Plus) , I used it for around 4 weeks without batteries, actually with 4 damaged car battery that give voltage without amperage just because the inverter could...
