Bosch 750s

I have a feeling the old ones are the same ones that are in Leveller at the moment...

New ones look good- hope they work well!

Your batteries wont be helping, they will only be able to supply 80amps, I run them in UFO and they just cant supply the current needed. I would suggest upgrading batteries before the motors, if you upgrade your motors you will still have the same problem.

[JamesDavies]

Really? I see... What batteries would you suggest instead?

Nicad and nimh are rarely used now, unless bought cheap from someone else, a123 are hard to get at the moment , maybe the only choice is Lipo, they can be inexpensive and you only need a few of them, making them a prefered choice for many roboteers now.
They Will supply serious amps at stall though .

I see- what do you use in Toxic Terry? I'll look into it... Is what sort of amphourage would be reasonable?

[terry]

I use 4 packs of a123 at the mo, they all add up too 9.2 amps (2.3 ah each.)
I could get away with 3 packs (6.9 ah ) but as I use around 4-5 amps a fight I like lots spare !
If they go wrong or when I replace them it will be with 2 packs of optipower lipos from grant
roboteers get 30 % discount, they are 5 amps each so 10 amp will be perfect, here they are-

That's great- thanks will look into it

James, you obviously will need new chargers. I suggest the cell pro chargers as they will charge all chemistry so if you get lipos or a123s in the future you will be ok.

I have some A123 packs for sale in the 'For Sale' section if you're interested. Slightly better for the beginner and less likely to blow yourself up - they're a lot more forgiving.
