    Safely tie together 3 12V battery stacks?

    I'm putting together a 12V 4S3P battery system with (3) HXYP_4S_3828_BMS battery management system modules, each managing one of the three stacks. Can I safely tie the three stacks together at the 12V terminal? My concern is that there may be a slight voltage difference between the stacks. The...

    Determining total current draw, in a system running multiple sensors

    In short I'm trying to estimate the current draw in a remote weather station, to dimension its battery pack and solar panel accordingly. The way I'm thinking of involves writing down the current draw of the system every min and then multiply this number with 3600 to get the current draw for...

    Does the MOSFET in the Schematic will work fine?

    I using the MOSFET IRFB3004PBF switching. 56.2V is a source voltage coming from the charger and 48 is the nominal voltage of the batter. switch S1 is for switching Vgs. Vgs=5 v. Rgs=10k ohms (connected to the gate terminal and battery ground). battery is 13s3p Nominal=48v Peak=54.6v Will MOSFET...

    Need help with setting up LiFePO4 battery parameters in a Solar Charge Controller.

    Hi, I am trying to set up the parameters for a LiFePO4 battery bank for a solar charge controller. I have tried to search the internet for understanding the basics of LiFePO4 battery but couldn't find any source from where I can understand the logics to calculate the parameters. So please pardon...
