Hey all
Was considering if running onboard batteries would be better since I read that the battery to esc lead on a brushless esc shouldnt be lengthened otherwise it could damage the esc. Is this true?
What batteries would be best suited for onboard use
Lipo, SLA or NiHm/Nicd?
Can a brushless esc suited for lipo and Nihm/Nicd be connected to SLA batteries and a PSU?
And How can You work out approximate runtime of a battery (dont want like 10 minutes runtime with onboard :mrgreen: )
Thanks

Re: Onboard batteries
if you where to use batteries for power you should probable use lipos because you will get a longer run time. but if you use batteries it will in cress weight.
what are you going to use to control your ROV?![Smile :)](./images/smilies/icon_e_smile.gif)

Hey
Ill be using a arduino. Yea I think SLA or niCd/nimh would be better since they decrease buoyancy
Lipos are probably also a not so good idea since they can catch on fire ect
I already asked this in another thread but how can the pc to arduino cable be extended easily by 100ft besides using usb/ethernet extenders?
Thanks

Re: Onboard batteries
Li-pos only catch fire if they are damaged. I have been running Li-pos in aircraft for a while and have even crashed them with out a problem. They have a longer running time and less bulk and weight of batteries of the same rating. The only thing that I would recommend is that you insulate them to keep them warm. They have diminished capacity in the cold.

The image shows Lipoly Packs broken in 60m depth. No fire just damaged by shorten circuit.
