Balancing tab configuration?
 

i bought a hyperion charger and want to put balancing tabs on my a123 packs...
i am not sure how they go on there?! can someone help me and show me how to wire them?

thanks,
G

Start here - its discussed in there somewhere or theres a pic of one wired so you can get the idea. Def buy the hyperion 7 wire a123 balance tap harness -

Lastly chase down the LBA10 balancer manual, see top of last page I believe for a wiring diagram -

The wiring is very literal.

You're the man...

thanks,

p.s. i just looked at the manual, a bit confusing for me, ha ha. have to study it for a while...thanks again.

Its really simple, but it takes a little to figure out what needs to be done. I've got some notes somewhere...

Def make sure you follow the wire harness note - all thewires you're actually going to use have to be the same length. My 5S and 6S pacs are big enough, I didn't cut them, just taped them down and out of the way.

I didn't do this on my 1st one, I cut them - that note wasn't posted on All e RC yet and finally had to ask why my 1st pac was taking forever to balance!

thanks for all the tip! if you find those notes, please let me know...

...i don't really get it?! what is the LBA10-A123 manual for? just for me to see how to wire the tabs, right? if i have the hyperion duo, do i need anything else to charge the a123 packs? what i don't get as well is: if i want to put balancing tabs on packs that are in series, i kinda get it. but if a pack is also in parallel, how is that gonna work?

thanks,
G

p.s. i have PC power supply that i was using for my sonic a123 systems charger and my triton...it has 255 WATTS at 12V...i should be fine with it, right? why using one that costs $100 bucks?

I'm still looking - you solder the balance wires directly to the cell - Deans solder worked without any probs.

As far as the PC PS - yes, it'll work fine. 255watts - DUO is basically 2 chargers built into one case - that power is shared. If you push the power on both sides, there will be a limit.

I didn't do parallel - I made 5S1P pacs and then externally, wire them in parallel, but I charge/balance them separately. I think you'll have to wire them for two plugs and build a parallel balance harness to hook them up. Not certain about that though....

LBA10 was out really early and Hyperion put a lot of stuff in there that was coming from customers.

DUSTER?!?!?! where are youuuuu?:blush::blush::blush: i need your help buddy. gonna get my tabs today or tomorrow...already have the charger. if you find your notes, let me know asap...

thanks,
G

I'm here - haven't forgotten you. I'll post back when I get home today.

You bought the hyperion a123 harness??

yes, the one you showed me. they are in the mail. ETA today or tomorrow...
every diagram i see for wiring balancing tabs are for cells in series but not in series and parallel...cant be that hard?!

thanks,
G

Good, think thats half the prob, getting the right harness.

When you get the harness, there is one red wire and 6 black wires. The red goes to "pac positive". I put it right next to the red main power lead going to the deans. For series, there will be one more wire than # of cells. One pac positive and one wire on each. Parallel shouldn't be diff.

If you looked at the RCGroups how to, I did pretty much everything he did, except my 5 cells were in a side by side flat pac arrangement. Number them like he did and wire them in sequence - the 2nd wire in the harness, next wire down from the red wire - the 1st black - is the neg for the cell you used as pack positive. The rest - follow the numbers you put on the cells in order on the plastic connector.

Nice thing - mock this up and connect it and see if it works before you make anything permanent. Some solder will need flux to stick on the tabs, I didn't solder to the cells themselves and Deans solder didn't need flux.

i should have them by tomorrow...i am sure i am gonna screw it up :lol::lol::lol:

Think positive.....lol! I screwed my 1st one up....its allowed. Just test it before you make things permanent, all that strapping tape I had to cut off was the pits.

believe me, i invented screwing things up, ha ha.
