I need your help for a challange.

The goal would be to power a 150 kW electric engine for the duration of 30 s to 1 min. Afterwards the batteries could be broken (so only one use).

I found some performance data for engines, e.g.

Mass 43 kg Power 150 kW Operating Speed 10000 RPM Torque 460 Nm Nominal voltage 650 V

and calculated a current of 243 Amps for 95 % efficiency.

The goal would be to find a battery that is very light weight and able to be drained within this short time.

The best I came up with so far would be the

**SLS APL MAGNUM 4400mAh 14S1P 51,8V 45C/90C**

which could provide the necessary voltage with 13 packs in series.

However I think there is still potential for a better solution.

The batteries could also be primary batteries (non rechargeable) as it only has to work once.

I don't want to give any cost restrictions for a solution so it can also be high prized, important is only the weight and fast discharge.

I would really be happy if you could help me on this,

Best regards
