For LiFePO4 the current limit is typically the Amp-hour rating or a small multiple of it, ... --------------------------- Which means that a 12V, 100Ah LiFePO4 could ideally power a 1.6 HP motor for an hour. 16 of them in the BMS maximum 4S4P configuration equals 25HP. I had such an engine in a Beetle, whose 0-60 time was 15 minutes while the tranny oil warmed up. That was a good excuse to avoid the Autobahn and instead wander through picturesque little villages on service calls. At the time the Autobahn was a squareish loop around the edges of Bavaria and cutting across diagonally was nearly as quick, plus a Jeep or Army truck wasn't much faster and I couldn't leave them parked outside a Gasthaus overnight.
