Some more questions... which one?

[padailey]

I heard that driving on one pack that ti will last long when you charge at less amps, and when you charge at more amps, the pack has more punch... is this true?

Charging at less amps than 1C will be fine it'll just take longer to charge. It is not true that you will get more punch charging at higher amps... that may be true for Nimh's but does not apply to lipos. Charging at a higher rate than 1C is becoming more acceptable as lipos get improved but from what I've read it generally shortens the life of the pack and all you get is a quicker charge. Generally at 1C it takes a little over an hour to charge a pack but the first part of the charge up to 4.2 per cell doesn't take near that long. The last bit of filling up the cells takes quite awhile but once you hit 4.2 per cell it is close to done anyway.

Just to follow up with what others have said DO NOT leave the pack at near 3.0V per cell... that's too close for comfort IMO. Longer term storage at 3.8V per cell otherwise for short term storage just make sure it has some juice in it. Full is fine for short term also.

My hot bodies lightning came with 5k all round, I've swaped the centre to 7k for a little more on power oversteer.

The thicker it is the more power will go to the rear wheels and less power to the fronts, leaving the fronts with more spare grip for cornering,

I think that 20-30k is taking that too far and would behave like a Rwd car and either oversteer too much, or transfer too much weight to the rear lifting the front off the ground and preventing steering totally.

Uh oh, I ordered 30k since everyone said this, I hope it turns out all right. It really is a pain in the arse for me to rebuild the center diff.

[jnev]

Just received the 30k diff weight. I have never had a vehicle with a center diff or one where you need to fill the diff with oil, since I have only had the rc's in my signature below which didn't require oil. Just grease.

So my question is, how much do I fill it up? I heard half way, but wanted to make sure. How do you know that it is half way also?

Thanks

I already rebuilt the center diff, but still haven't ran the car except for one pack.

I have everything set up on the charger, except for 1 part of it. I entered lipo, for type, charge for mode, 8000 for mah, 8 amps for current, 120*F for cutoff temperature, and then you have to put something in for "volt". I clicked the arrow pointing up, and nothing happens. I click the arrow pointing down, and it goes to "1C" then I click the down arrow again, and it goes to "2C", then 3C, etc. Do you know what to do at this part?

I would really like to get the charging done today to run it tomorrow.

[jhautz]

Its asking how many cells. 2p pack is 2C, 3p pack is 3C, etc...

[jnev]

Oh, I see. Great, thanks a lot. Off to go charge the battery. :)

[GorillaMaxx360]

what are you charging it on.

[jnev]

Superbrain 989 with the LBA10 balancer.

I didn't have time to test the charger earlier. But I tried it just now, and it says that incorrect information has been entered.... "error BL." Which in the manual says that this means that the voltage is too low in the battery. But I used a volt meter, and it says just over 13 volts, so it can't be too low. Anyone with a 989 want to go over all the settings with me.

That would be very helpful. Thanks.

it does that to me when im out racing, i just push start again and its goes, mite be something wierd, but it only did that with my ib packs and i dont even use half there mah so yeah its kinda wierd

and wow c is cells, i was waay offf, see y i dont help with that kinda stuff lol? glad i didnt

[jhautz]

I have the 989 and it has alot of failsafes built in so you dont screw up, but its not foolproof so make sure you know what you are doing here.

Tell me what packs you are trying to charge and I'll give the exact settings to use. Be as specific as possible so I can make sure to tell you correctly.

[jnev]

Well, tried it again and it has been charging for about 30 minutes now. I must be getting the same problems that e-maxx got while racing.

jhautz - I'll definitely let you know if I have any questions about the 989.

yeah, IDK y, i dont care really, i want some high end stuff from much more but thats 250 bucks plus all the otehr stuff i want... but this is the BEST basher charger... HIGH cell counts and lipos etc:018: :018:

So far its a great charger. I've charged 1 NiMH battery and 1 LiPo and so far so good.

I had just one question though. Is it all right if the battery stopped at about 8700mAH when I put 8000 before charging? It stopped at exactly 16.8 volts so thats good there I am pretty sure. If the leads on the balancer are still flashing, does that mean that it is still balancing? I have already unplugged it, but want to make sure for next time. What do the flashing leads mean as well?

Thanks so much guys for all the help so far.

yes thats normal with batts, well not matched and zapped batts, they have moe voltage in them then MAH

but thats normal!!

and idk on the ballancer
