the new watty speedo has arrived, what can i say very nice. looking to change the batteries in the robot as they are big,heavy and old. it runs on 24v (used to run on 2 4qds) and has 4x Gastron 12v 18ah?, i think their from a golfbuggy or something. all im running are 2 bosch 750w motors and the hydralic weapon, can anyone recommend something that will give me as good performance, save some weight, (on a budget with this), and need a affordable charger to suit also.

either NiCads (will prob cost abot £500 for a setup with chargers), or look at the 13Ah Hawkers, slightly smaller/lighter than the normal 16Ahs and can supply loads of current and will be much better than waht you currently have.

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

Upgrades

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

[ady]

Upgrades

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.
