Recovering the 280AH system LiFePO4 24 volt system.

 I just received a 

JK BMS V19 PB2A16S10P | 100A Continuous Discharge | 2A Active Balance | 8S-16S Li-ion/LiFePO4/LTO Smart BMS - JK-PB2A16S10P+7" Display.

My 280AH system LiFePO4 24 volt system; lo and behold the old stack drops a cell - short circuit.  The batteries are about 5 years old and have been part of an off grid RV Mobile Home.

So do I buy a whole new pile and make up a UPS using the remaining old cells ?  I believe replacing one cell is a no go.
