Battery Life

[RCDad]

I'm still getting about 10 minutes of playtime out of my crap batteries. I charge them for 15 minutes on my dynamite dual-e. I figure they are doing their job.

Another question, I have two V Maxx Super Duty 2400 mah sticks. They get hot super quick whenever I charge them so I take them off, does that mean there pretty much shot?

Was there a question here?

It could mean that you're charging them at too high of an amperage. Try charging them at 3A. Or you could try cycling them....discharge them and then charge them at .3A, repeat 3 times and see if that brings the pack around.

Also, you might have a bad cell. If the pack is worth it to you, If all else fails dissassemble the pack and find the bad cell and replace it and cycle the pack again to equalize your cells.

The packs gets hot, but how long does it last when you run it? Do you get good power out of them?

On a final note, I've had a few of the same packs your talking about.....they're crap! I picked up 2 packages for a total of 4 battery packs. Out of all of them, only 1 still runs decent.....and I take care of my batteries! So, IMO get some new packs.

If you really want some more power out of your E-Maxx, get some 7-Cell packs. It will be a world of difference.

You cannot adjust the amperage on the mega dual-e, all you can do is set a timer. However, I believe what your saying that thier total crap.

If you're planning to get new batts, I'd recommend Reedy match packs. 3300 NiMh. Excellent. The other advantage is longer run time and no cycling. However, you'll need a charger that does NiMh, and charge time is longer. I never get NiCads for anything anymore.

Are you saying the mega dual-e is not for nimh batteries? The way I use it is I monitor the battery temps. I have a graph that tells me how long they should be charged for but I try to use less time and go easy on the batteries.

I'm not familiar with that charger. Mine has separate settings for NiCads and NiMh. Check your manual.

I called the company and asked about amps and safety. They told me to monitor the battery temperature.

I wish I knew more about electronics, I'd install a fan inside the charger.

You better wait for more replies on this. I have a Dymond Super Turbo battery charger. $120. It's doubtful it would have separate settings for each type of battery if there wasn't a good reason.
I can program in any settings I want for either one, and if I have a 3300 NiCad, and a 3300 NiMh, and set them at the exact same charge rate, there's a reason I have to program it to tell it which one I'm charging.

 

[RCDad]

I looked on the website and this charges at 3.5 amps.

 

[Rolex]

That still doesn't tell you if you can do both types of batts. Any chargers I've ever looked at specifically state that they can charge both NiCad and NiMh if they are designed for that. If any references there are just for NiCad, I'd wait for more info here, perhaps from someone who has that same charger.

 

[RCDad]

Yeah, it definitely does not specify, but, its all I have so.

Whats interesting is the Mega 2 specifies that it does both but it charges at 4 amps, which to me seems high. I wonder if its just the fact that it has a discharger and a rate meter.

This site http://warrickcustomhobbies.com/inside/store/product.php?id=3419&cat=174 says it will do both, not sure where they get their facts.
