Batterys

[djdoug99]

I charge my batterys to full charge and then I will come back a day later and they will be totally drained? Anyone know whats going on?

What kind of batteries? Are they in the car or controller?

 

[djdoug99]

I've got 8 AA 2300 batterys in my M11. One thing about the M11 is I'm having a hard time figuring out how to be able to leave the battery pack in the M11 while it charges, is this possible?

 

[Rolex]

I also have the M11, and I don't see an outside charging jack.
I still have the alkalines in mine, but will go for the NiMH pack soon.
What type of batts do you have in there? Nicads, NiMH?

 

[djdoug99]

NiMH. They are almost brand new. The M11 battery holder is so damn hard to get out that I have to take all of the batterys out so I can get a good grip on it. I'm probably going to be building a pack for this reason.

How are you charging them, in the holder, all at once? What kind of charger, and what settings are you using?

 

[djdoug99]

SuperBrain960. I am charging at 0.5 amps. I am charging them all at once in the holder. What happens most of the time is that the charger will false peak only with these batterys ( I can charge my receiver pack fine ). It was false peaking so much last week I had to miss a qualifier, and when they do charge, the next morning I will check the battery and it would be totally drained while not even connected to anything.

Here are the batteries I am using http://www.amainhobbies.com/product_info.php/cPath/1_221_224/products_id/2361

Odd. I'm thinking you might have a bad one in the crowd draining the rest. Try charging them one at a time and checking the readings on each.

 

[djdoug99]

Checked the readings on each and found one that didn't have a charge. I charged them all at once and took that same one out and it still has no charge. Guess I need a new battery.

Thanks

You need to charge them with the bad one REMOVED.

 

[djdoug99]

I charged them with the bad one removed. I charged 4 at a time in another pack since I couldn't charge the 7 in the 8 slot battery pack unless I closed the circuit which I didn't feel like doing.

Anyways, I got around 5.85v for each at full charge. When I woke up this morning they were at around 5.60v. Are they supposed to drain like this?

 

[Rolex]

That's not much loss for a battery hot off the charger.
How long have you had them, and how many times do you think they've been charged?

 

[djdoug99]

They are still pretty new, only have about 5 charges on them.

when building a AA pack, what is the best way to connect them? It seems I can only find battery bars for the Sub-C batterys.
