Charging problem
 

I'm trying to charge my lipo's for the first time & no luck. I plugged them in to the lba6 balancer as per directions. The leds flashed five times, they all went out except cell #2 & cell #4. I plugged the balancer into the charger, & started the charger it said no battery was connected.

After you plug it into the charger you need to push the button on the LBA6 and change it from stand alone mode to charge mode. Then it will pass the voltage throug the LBA6. Just be careful after you push the button the leads on the LBA6 are just like the battery leads. Dont short them on something by accident.

It's working :043: :027:

Three of the 4 led's are light. Led #1 is off led's 2 3 4 are on. What does that mean ?.

Cool.

That means that cells 2 3 and 4 are higher voltage tha cell 1 and its dischargeiong 2 3 and 4 to make them the same as 1.

Thats what its supposed to do. Its working. Your all good.

Now led's 123 are on & 4 is off .

Cells 2, 3, and 4 flashing mean those cells are higher voltage and the LBA is slowly discharging them until they get to whatever cell 1 voltage is.

The LBA is fairly sensitive so different LEDs might go on and off. That is normal. If the LEDs go from flashing to solid, that means the imbalance is larger and you should reduce the charge current so the balancer has time to discharge the high cells before the charger gets to the CV mode.

Okay but how will i know when they are charged , the packs are 8000's & the counter on the charger only goes up to 5000 ?. The manual says i can charge 800's it will just take longer.

It working. Stop worrying.

That means you can only charge at 5 amps instaed of the 1c rate which would be 8 amps. Its still stop at the correct voltage.

Im only wondering how will i know when there done ?. My triton used to beep when finished i dont know what this one does when finished. This is my first exsperince with lipo's so i'm a little nervus :005: .

As long as it is true cc/cv charger..... quit worrying!

My charger is a hyperion eos5idp . But how will i know when there done ?. I've only had NIMH chargers. I've never used a good charger like this.

Just monitor the voltage and current. Once the pack gets to 4.2v/cell, the current will start to drop and eventually will dwindle down to 100mA (0.1A) and then stop. Charging an 8Ah pack at 5A will take 96 minutes, assuming that charger will do 5A at 4s voltage without hitting the power limit.

sorry i did'nt even see this repliy LOL :005: .

no .

After using my lipo's & they cool off can i just put them back on the charger or do i have to do something else first ?.

Just let them cool and charge them up.

Thank's for answering my ?'s. 4S lipo seems to have as much if not more power & punch than the 14 IB 3800 cells i was running LOL :005: .

I stopped waiting for the balancer to stop blinking before i charge the packs; just charge them with the blinking lights, the balancing process goes faster when charging. (or you don't need to wait for it)

Thank's for the tip rene. Did you find out if you had any of what we talked about ?.

not yet; what is your plan? perhaps i can make you something.

with you batteries Just tell them who's in charge.. (and with these words , the price for the 'worst joke of the day' is already taken by .....)

LMAO :005:

I'm making something very similar to what the mbx 4 had for a fan mount. I have exactly what i want made from aluminum but was going for the BLING BLING factor of CF LOL :005: .

It it a mount the looks like this with the fan mounted on the horizontal part & the vertical part is only about a 1/2 inch or so wide so i can mount it to the mount i made to connect it to my ESC mount. . The fan mount will screw to the reverse mount i made. I hope this makes sinice to you ?.

I think i still have the mount you used.

I already made another one of those in aluminum. I was thinking abount making one out of CF.

i just talked to jack at HYPERION & he said there is no added benifit of balanacing my packs everytime (per say ). He also said i could make up a cable that goes from the charger straight to the battery, & charge them that way & balance every 4 or 5 charges. My ? is if i charge them without the balancer is it safe ?. He also said the battery would charge faster not being connected to the balancer. I dont think im comfortable doing that. Any thoughts ?.

You are probably ok with not balancing everytime, but why not do it? It's not going to hurt anything and you can be sure that your pack will always be balanced. I balance while charging all the time. Any decrease in charge time by not using a balancer is negligible. Technically, since the bal does discharge at a low rate, charge time does increase, but is so small that it really is not worth mentioning IMO.

I agree with you & i feel safer using the balancer evertime.

I dont balance every time. I have more chargers than balancers so I just balance every couple charges or so. I rarely find anything that take more than few minutes to charge with the exception of some of my older 10C packs that get pushed very hard and tend to go out of balance more. But even they arent that bad.

Well, if you don't have enough balancers, that's another thing. I only have two chargers, so I have two balancers. My Hyperion charger acts funny though no matter what lipo battery I use. Once the voltage gets to ~4.1v/cell, the charger errors out ("output voltage too high"). The only way I can get it to not do that is to lower the charge current to about 3.6A. Weird. So, I use that for all my NiMH and the Xtrema for the lipos.

Are lipo's like nimh in respect to when the charger shows they are finished charging you have to use them right away to get the best performace, or can i use them two or 3 days latter ?.

You can use them three days later and they will still be almost fully charged, and there won't be a power difference after three days. However, it's best to keep Lipos at about 3.8v/cell when not in use (storage), so keep that in mind.

Im new to this lipo stuff how can tell if each cell is 3.8 & will it hurt if i store them higher than 3.8 ?. I'm assuming i can just measure the pack voltage as a hole ?.

I just figured out i can use the balanceing tab to measure each indaviduel cell.

I usually just run my vehicle for about 1/3 of the normal runtime. That typically sets the voltage right around 3.7-3.9v per cell. Yes, you can measure the pack as a whole and divide by the number of cells, but this assumes the pack is balanced.

Does it hurt if you store them with more than 3.8 per cell ?.

I can't remember exactly what happens when you store over 3.8v, but I do know it is better for the cell. I don't think it will explode or anything.

So after your last run of the day what is your rutine for storing them ?.

Is it bad if they are stored for a couple days with no charge? I ask because I am waiting for my charger in the mail, and surprisingly, the battery came fully charged, so I ran it.

Anyone know? Sorry for the thread hijack...

A couple of days is ok. A week, maybe. Longer; run it down to 3.8v/cell.
