Thanks!

If that delta (at 56.4 and 48) is without a balancer than i wouldn't even use one! ? Amazingly matched cells! Sure, right now (subject to change) charge stop at 55.2v (because we have a runner cell but maybe the a30 and the new threads (a few were stripped) will hopefully reduce that issue)...

Can second that, works great, hooked also one up to our 16s battery with an Ant-bms. Super easy setup, top functions.

Mission to one of the smartest and feature richest solution finally accomplished! @octal_ip guided me with his really patient and kind being successfully through all the hurdles i encountered (and there were quite a few for a greenhorn like me) towards the final completion of his working super...

First download the overkill app and check your capacity configuration settings, especially the 100% to 0% voltage values, if there is anything unusual.

Tested a 5000mAh cell with my Ebc-A05+ tester. Results: Voltage while charging with 0.4C SOC (two test rounds) 3.40V 77.5 , 78.7% 4.45V 94.1 , 94.9% 4.50V 97.6 , 97.9% 4.55V 98.4 , 98.6% 4.65V (Without absorption) 99.1 , 99.2% 4.65V (With absorption) 100% Voltage while...

Guess not much significant harm to do this briefly once for the sake of science. I read in studies the longer you leave batteries in a fully charged or -depleted state the more harm is done. Left in a fully depleted state is even more harmful if i remember right. For example I read fully charged...

Many thanks for your input and suggestions! Will check what i have available here or on AliExpress.

Should i better get an MCCB like this? Not sure where the difference between the MCB above and this MCCB lies but i have seen them frequently installed between battery and inverter. Advantage maybe is that they use ring terminals, more contact area. DC12V DC24V MCCB Circuit Breaker 150A 200A...

Hello I just saw a few YouTube videos about dc circuit breakers going up in flames because of wrong wiring etc.. We use following breaker between our 200Ah 48V Lifepo4 battery and 5kw inverter. It's mainly used to isolate the battery during maintenance work. DC MCB 24V 48V 96V DZ47 circuit...

1. Bms calculates soc via coulomb counting and estimates through reference voltage values (100% to 0%). How it seems to work: In real time it uses coulomb (doesn't reference to voltage), if manual reset, reboot, change of values in settings etc it uses the reference voltage values as a first...

My pleasure, happy if i could be of help.

Sorry i have to correct myself, the jbd counts everything but doesn't show anything below 4-5w. The bms should be more accurate than pzem. Bms also counts coulomb. Just use this discharge to get to test compare etc your meters and bms. Important before you start your capacity test (start...

Also, ideally for this test, don't charge or discharge your battery with more than 0.5C. 0.5C of 200ah is 100A! Check in the datasheet of your battery which charge and discharge rate was used when they did the factory capacity test.
