Hey guys I have a change to pick one of these up for $10, but the question is...Can I charge my hump packs with it. I did a search and it doesn't look like that. The lowest charge rate is .5a, what are you guys charging you packs at?

Help:confused:
 
I have been charging my hump packs at 1.0 amps and delta V cutoff at .25mV. It takes about an hour to get a full charge.

doesn't your charge rate depend on the mah is on the pack? i have that charger and i use it to charge my rc18b battery. i charge it a 1 amp sometimes 1.5 with no problems. what the mah on the pack you want to charge?
 
It does and it doesn't. The slower the charge the better it will be. I think the average rate is .5a per 1000mah, but I'm not sure.

I'll be charging my hump packs 1100ma and 2500mah, and hopefully my glow stick and radio batts.

if what your saying is true about the charge rate you should be fine with the .5 but i was told to charge batteries by 1amp per 1000 mah which is why i charge mine a 1 amp(the battery 1100mah)
 
I am using the 969 Pro, the 959 has adjustable delta V cutoff which is what I depend on when charging packs. One of the differences between the two is that the 969 Pro is adjustable in increments of .1, while the 959 is adjustable in increments of .5. I use 5mv per cell in a pack to figure out the delta V.

You'll need to make an adapter for the 959 to charge your hump packs by using a tamiya plug and a female servo plug.

The safe quick charge rate is 1amp per 1000mah rating on your pack. So for example

1400mah pack can be charged at 1.4 amps
3600mah pack can be charged at 3.6 amps

so then i was right? also it will only take like an hour to charge give or take a minute.

you are getting a real good deal on this
 
it will take an hour like stated above.

Example....
3600mah = 3.6amp hours
charging at 3.6amps it will take an hour to charge.
 
Hump packs I would always charge them SLOOOOW when practical,overnight slow charge.

The 3300mAH = 3.3AMP or 1100 = 1.1AMP charge is not of much value unless you have LOW RESISTANCE quality cells from GP or Intellect.

As these high discharge cells can be charged fast and produce little heat.Use this rule on cheapo higher resistance cells and you will have a boiling hot or at least hot cell pack.

For hump packs and cheapo cells I use a 4 to 6 hour charge,so a 800mA pack will be charged at 0.2 AMP(4 hour charge). The packs will last longer and be stressed much less.
 
Great info guys.. I was still confused about the whole battery charging process.. I always let the charger figure it out for me... Superbrain 959
 
I've always used the 1 amp/1000mah rating in conjunction with setting the correct delta V. I also let the pack cool down before I use it. Haven't experienced a pack failure yet.


Of course now that I have said that my pack will die tomorrow lol.
