Just coming back on to say thank you for the help.

The route i went with was to parallel two of the fets that i put in the first post. The reason i took this route was i had already...
I've taken a picture but all it is is a PCB with a switch and a Fet. There are no components on the bottom side of the PCB. It does connect to another PCB but that is the LED driver board.
Looks like my only option is to parrallel 2 Fets.
Thank you for the reply as my electronics knowledge...
Ok going to work tomorrow and will have a look to see what fets are available and maybe have a word with the electronics engineers about the best solution. If all else fails i will experiment myself with what is available and try to get it working.
I had a cell go down to 0.943V under its own self discharge (5800mah turnigy 25-35C). It had always been a little weak from new as on the first charge it was hard to get it to balance with the other cells although after a few cycles it was ok although it did have the problem of discharging...
Bought a Sealey cordless ratchet CP2144 which came with 2 ni-cd batteries. It's a bit bulky but comes in very handy for certain jobs.
Today i emptied the ni-cd from one of the packs and fitted 2ah of 20-30c lipo. The packs were 14.4v and i have fitted 4s lipo. The ratchet had a really nice...
