BTW ...Ady,
You could consider increasing your Pack voltage to 30v ... your Chargers ...as I recall will do 30v packs... that is assuming the Wooty will also handle the voltage.
Just a thought
absolute max on a watty is 32volts, so should be ok.
i dont know bout that, i have 12ah of 28.8v packs and when fully charged are putting out over 37v for 5mins
kenny, im just going on instructions i recieved with mine last week from ian watts and to quote absolute maximum voltage 32 volts, you will damage your wotty above this voltage and it also says under how to kill your wotty, number 2 (connect more than 32 volts to it),

Kenny is pointing out that the 30v Nicad packs .....when freshly charged .... will have MORE than 30v in them.
Therefore your Wotty may go POP!
Check with Ian to be safe.
I couldnt remember the terminal voltage of a freshly charged Ni-Cad cell ( nominal voltage 1.2v ) ....Google suggest around 1.4v per cell... this would initially give you 35v on a 25 cell 30v pack.
1.6v...
Well ...That seems to suggest that the Wotty is only going to be OK for a fully charged 24v Nicad pack.
Re configure the packs to give a max voltage of 30 ? (take a cell or so out ?). Im sure this would still make a resonable increase on 24 v whilst still makeing the most of a Wooty.
(PS Whats a Wooty speed controller of some sort)
24v pack is 20 cells.
20 x 1.6 = 32v.
So no more than 20 cells (24v nominal)
