View Full Version : Question about "Electic Power" packs

I know theres no industry standard for tap connectors so I was wondering if anyone could answer this question. I bought one of these packs at the link below (its on the way) and am wondering about balancing. It comes with balancing taps on it, and is a 3 cell 1300 mAH. The balancing plug on it I see only has 4 wires (click on pic to enlarge). Does this mean that only one negative wire is hooked up to it? So to get all three cells voltages, I would test each color with the black wire? I plan on getting a trition charger, and want to be able to balance my packs. Also, if this is true, any suggestions for a connector I can use to hook each cell in, while using the single negative wire?

VAMPower & 2DogRC (both Dual Sky)& Electric Power use the following for 3S packs.

Corrected 12-14-05
1-Black -VE
2-Yellow +3.7v Cell1 (and - for cell 2)
3-BLue +3.7v Cell2 (and - for cell 3)
4-Red +3.7v Cell3

Male connectors are same as used on IPS and 350 brushed motors.

You could use one of the IPS / 350 motor connectors to check or charge single cells.

More balancing information here.

Great info Charles! I was going to ask the same thing. Now where do we get the plug end that goes to the pig tail coming off the pack itself?

To translate Charles's technical info into plain English for those who don't necessarily understand electronic "technobabble:"

The two middle wires serve a dual purpose. They're the + for one cell and the - for the next cell. To test or balance individual cells, you would connect to two adjacent wires.

You can't hurt anything by trying different combinations of wires with a multimeter set to VOLTS, so check it out for yourself. If you hold your black probe on the black wire, then touch each of the other three, you'll get 4.2V, 8.4V and 12.6V, respectively. Move the probes together so they're always on two adjacent wires, and you'll get 4.2V, 4.2V and 4.2V.

Neat I learned a new word today,thanks.

A picture / drawing is worth a thousands words so.Courtersy of Thunder Power by way of TP-205 Smart Balancer User's Guide.

Please note that not all LiPoly vendors use the same cell numbering sequence. Some start atr the neg . for cell #1 and some start at the negative.

is two each 2 pin connectors(pigtails) such as comes on most IPS and 350 size brushed motors.I have seen these refered to as being ESC connectors. Each one has one red and one black lead. Place them side by side Red Black / Red Black and glue with CA.

Here is a picture of the connector furnished by Polyquest and the way that I have wired it. Count from left to right
Pin one, the red wire, to pin two is the first cell.
Two to three is cell two
three to five is cell three.
Pin one to pin five is total voltage for the pack.
That is the way the polyquest 3s1p tap is wired and that is how it is test.

When you read 2s1p it reads 1-2 the 2-5, one to five is total voltage fo the pack.

1 2 3 4 5
- +
- +
- +
_ +

Not sure if this makes sense or not.:D

I tried.:o

Next time I will make a drawing and take a picture.

I drew a graph with the contacts and it gets edited out when I save it.

OOPS! :o Sorry about that. I thought he was using the 2 pin connector for the balancer end. I just ordered a couple TP balancers so I couldn't look at the plugs as they are not here yet. I also ordered the pigtail to hook to the balancer so will go the two pin method unless I can talk Vammy into sending me the correct plug to fit the Dulskys.

OOOoooh. Very cool. Thanks guys for the info. Info I just happen to have been looking for! I I have a couple of Vammy's packs (love um!) and asked Vammy what the pin-out of the balance plug was and he never replied....
