Daly BMS MOSFET details?

[MullerEnergy-Australia]

Does anyone know what MOSFETs are used in a 4s LiFePO4 250A Smart Daly BMS (or similar model)?

I want to do a stupid experiment and want to confirm it has a decent chance of survival.

I've got the details of my 300a 4s written down at home, I'm at work atm I'll get them for you when I get home next week.
From memory they were 30v 60a and there was 32 of them, can't remember the brand I've looked at so many recently.

Do tell us more about the experiment.

There is a thread which shows a knock off daly fets.

I am modding a 7s 20A BMS for more current output of about 60A, I have some 120A mosfet (FDP075N15A). CAN ANYONE tell how many of these i need in parallel and series?

But this number also depends on desired target RdsOn/max acceptable heat dissipation.

Already built the circuit and attached to an 24v 100Ah battery pack. Used total 16 MOSFETs (8 MOSFET's back to back), and now its running cold on around 50amps load.
