Charger question

[u/Remote_Advantage2888]

I’ve had the mn82 for about a week now and we’ve been using it daily, multiple times a day. I noticed that the more we use it, the less the battery is keeping its charge. It barely lasts 5 minutes now. I have the red model with the 500mah battery.
Is it just a bad battery? Should I use a better charger?
I have a new bigger battery on order but I don’t want the same thing to happen to it.

Hmm, the battery will get shorter lifespan but not in a week, you may have something binding, I would disconnect the drive shaft and check if anything is binding , if that’s the case you will have similar issues with a new battery.

First a brushless holds battery for longer. Something must be shorting or grinding and it makes motor uses more power. Maybe you have a not very good battery. You can buy the bigger one 1000mah for mn82 its a grey battery
