Battery problems
I have an rc carv9.6v pack that can read 7.5v on a meter but appears to discharge the instant I try to connect it to the esc...faulty battery?
Any advice appreciated

NiMH or NiCd cells?

Re: Battery problems
You need to test the battery on load you can't just connect a multimeter to it as this causes a short and have possibly now damaged the battery (I may be wrong I am no electrics guru).

Sounds like a new battery.
Re: Battery problems
A reading of 7.5 on a 9.6v pack indicates that at least one of the cells is knackered, but more likely all will be below 1 volt - well past saving I think. You could try breaking the pack down to individual cells and charging them independently, but it's probably easier just to buy a new pack.
There is a site called http://batteryuniversity.com/ which is great for all types of battery - it will tell you the minimum voltage such cells should go to - typically end-of-discharge voltage is 1V/cell, so your pack should read 8.0 volt minimum
NiMh are considered very 'leaky' when in storage, and need constant monitoring and recharging to be kept in best condition.

Re: Battery problems
Thanks Phil, they haven't been used in a while so probably I'm the cause! I've ordered some cell holders for some AAs I've got. I guess if one of those goes I can replace it easier.

Hallo,
since I use these Panas.... white Eneloop Accus, I got rid of all batterie problems. They are a little bit more expensive, but my eldest pack is more than 10 years old and runs very well.
