Hi Paul

I am starting from an empty board so-
I am thinking of
MOSFETS - Gigamos - IXFK140N25T -
140amps, 255nC, 250volts - slightly more current but 50 more volts

Diodes - SBR60A300PT-ND -
60amps, - 300volts - the reverse recovery is not as good 55nS as opposed to 27nS
Is that a killer???

Capacitors - EET-ED2E681CA
680uF - 250volts,

This would enable me to increase the voltage - ~ 180v??

I would like to increase the voltage as I am sagging a lot - I only have a small pack

2P - 44S of 16Ah Headway cells

I do intend increasing my pack size as soon as I can afford it

So Paul - Is this a good recipe? - would I be able to go to 700 amps? - 180 volts?

A assume I would also have to change the current sensor - and possibly the software

- Changing the subject entirely - Retirement funds?? - I thought you were a youngster - not an old fogey like me
