Default battery question

i am using a motor and batteries that have sat for two plus years with no use. Some times i get good power for most of the race, and some times after a few laps my power seems to go flat. Yes i know i need new ones, but i am just curious why this is happening or what may be causing this.

You've probably got a dud cell that's giving a false peak when you charge it and is discharging prematurely.

Most packs will self discharge over time, and if they get too low, the cells will slowly destroy themselves. After sitting for 2 years, I wouldn't be surprised.

You can confirm by charging, discharging and putting 1000mAh in the pack and letting it set for a week then checking it with a voltmeter.

HTH,
Chris

The problem could also be with a hung brush or other motor condition.
That would be worth checking into.

I find with some older packs they tend to false peak sometimes. You may want to keep an eye on what the peak voltage is when it comes off the charger or how many mah it's taking each charge
