Both batteries have 8yr warranty 15yr life. Both have Grade A battery cells and Pace gold standard BMS.
The main differencies are:
They have slightly different Cells LF304 vs LF100A in the rack battery (They are both listed as having the same cell pack assenbly, (which maybe a slight error on fogstars part, as each battery pack has different dimensions) They both have Grade A batteries.
The maximum discharge is 200A on the 15.5kW and 100A per unit in the 15kW rack battery (300A in total)
The 15.5kW batter has 304Ah capacity the 15kW rack battery 300Ah, which is nothing.
Cycle life is more on the 15kW Rack battery, than the 15.5kW
