Hi everyone,
I have four SOK 200ah batteries that I'd like to install in a motorhome. The motorhome is already set up for solar, but it has lead acid batteries, and since I already own the 4 SOK batteries that is what I'd like to use. The already-wired inverter (2000w @ 12v) and solar charge controller already support lithium batteries, I would just need to change a few settings.
The thing is don't have the space to drop in the 4 SOK batteries with their black box, but I can fit the 16 cells in 2 rows of 8 cells, so I'm thinking of doing that.
I guess I could use the existing 4 BMS in a true 4S4P layout, but I'm thinking of going with a single BMS in a 4P4S setup with this BMS, rated for 260 amps.
In a 4P4S configuration with a 2000w inverter, I need 2000 / 12 = 166 amps. So, it's going to be a walk in the park for the BMS, I would think.
Where I'm not clear is the discharge rate of the original SOK batteries, with its original max discharge rate of 130 amps (source). Is that maximum discharge rate a battery (or cells) limitation, or the original SOK BMS itself?
If it's the cells, a 4P4S configuration is probably a non-starter since 130 amps * 12v is barely 1500 watts (the inverter is 2000w).
Thanks
