Battery advise

[mattan]

Lock for hi current output on ths batteries, it is two types of it, low current output and hi current output. or ASK when you baying this on a hobby store.

Ah forgot about this but I recently upgraded from Sanyo 3000mAh NiCD Botpacks. Now ive switched to Intellect IB4200 NiMH packs, the bot does feel more alive and preformed well at Birmingham. Stalled an Ev Warrior for a period of time and burnt out two overvolted 18v drill motors at the same time, but still afterwards they was hardly warm.

Alex,
Try http://www.overlander.co.uk/http://www.overlander.co.uk/ we get all our cells from them and make our own packs. They will also give you a good discount on orders of 20+ cells!!

As Alan says the GP3700 are very good, we use them in Scorpion Evil, Batterbot, Small Torque & Pillow Torque. We have used over 100 cells in the last 18 monthes and have never found a single bad one.
Im using something a bit different in Pain In The Asp... 4 packs of 20 X GP 1300 2/3AF cells in parallel (80 cells in all) giving 24V @ around 100A!! (This thing is going to fly!!) :wink:

so how do you make your own packs, and which cells are recommendable?

thanks alex

I agree with Geoff , overlander is the way to go. I used the GP 3300mah in 24v config and they are great in my ram bot.

Yeah those are the ones , there are pricey but the performance of them is well worth the money.

so how many do you use? and how are they assembled?

thanks for the help
alex

[psycho_fling]

also are they easily made? or do you need some sort of battery making skill to be able to make a good job?
