    Top Balancing LiFePo4's, out after 5 days in service. My situation and some questions

    I'll try both of those suggestions. the other thing ill mention is when i did lower the voltage 'start balancing' setpoint down the BMS would want to balance a heap of cells at the same time (thinking about it thats probably due to my 8mV setting), when this happened the BMS would balance for...

    Top Balancing LiFePo4's, out after 5 days in service. My situation and some questions

    i Have 'balance active' discharge/charge and storage all set to on, balance to 8mV and balance at >3.4 cell voltage. Yes i thought i did destroy the BMS (and maybe i have) however current is flowing on the leads that should be balancing according to my tong tester. Ive decided to parallel up all...

    Top Balancing LiFePo4's, out after 5 days in service. My situation and some questions

    Ok, so i may have compromised my balancing because of the way i did it (I'll explain a little later). I recently put into service 32x 272aH Lishen cells setup as a 2P16S configuration. The cells all arrived reading approx 3.37x volts, i parallel connected all 32 and connected my CV CC charger...

    2x Chargery 16T's, 1x DCC ?

    if on the 4 pin connector (between the BMS and the DCC) the first two red and black are 'charger healthy' 12v feed then that will drive 12vdc interposing relay 1A and if the second pair are 'load healthy' 12v feed then that will drive 12vdc interposing relay 1B.......... same for the second BMS...

    2x Chargery 16T's, 1x DCC ?

    From the Chargery user manual, when using the Common Port example (on the left), only one DCC is required using a 4 core connector between DCC and BMS. So both scenarios you describe will switch the one DCC contactor, just have to work out what the pin outs are doing for each scenario you...

    2x Chargery 16T's, 1x DCC ?

    in that case i would have to use 2x single pole 12v interposing relays for each BMS, and drive one relay from the 'charge output' and the other relay from the 'load output' (possibly), series up the two bms charge relay contacts (on the interposing relays) and series up the two bms load relay...

    2x Chargery 16T's, 1x DCC ?

    it all depends on what the four cores actually do between the DCC/BMS, but ultimately all i have to do is interrupt the 12vdc to the DCC via interposing relays being driven from either BMS, and as per my (napkin) drawing above the DCC will be driven by either of the 2 BMS's via the interposing...

    Surely not for a common port setup ?

    ive gone the common port option

    2x Chargery 16T's, 1x DCC ?

    Does the BMS have 'communication' to the DCC or is it just a '12v on = DCC on / 12v off = DCC off' ? If it does have some sort of monitoiring comms between the BMS and the DCC then what i want to do will not work, however i cant see anywhere in the specs that shows the DCC as anything else other...

    2x Chargery 16T's, 1x DCC ?

    Yes, that i accept (re redundancy). Looking at the specs of the Chargery's there is no communications between the DCC (contactor) and the control board, it appears to be a 12v out for contactor on, or 12v off for contactor off, nothing more

    2x Chargery 16T's, 1x DCC ?

    Hi all, First time poster, and I've got to say how happy I'am to have come across this group, the knowledge here is unmatched anywhere on the www!! Anyway, apologies if this has already been covered, i did some searching and could find anything, and apologies for the crude drawing, however i...
