FlightPower V-Balance System.

[Alfie]

Hey guys,

I have a question on using the FlightPower V-Balance System.

I understand that this FlightPower V-Balance System can be used on many Lipos' setup.

If this FlightPower V-Balance System is used on the 2C Trakpower 4900Mah Gold bars (mainly used for Touring Cars), how do you connect it when the only centre hole is so small that only a probe can be inserted?

Please help.
Thanks in advance.

That not for a probe. A 2mm connector can fit into that hole.

Depending on how u charge and balance the pack. For me i solder a 3 point connector onto the charging lead and plug in the balancer thru it. Hope u get wat i mean.

If u need the connector i still got spare

Not really, when I'm still blurred with Lipo Technology.

I would mind buying from you. Let me know.

This is what i did for myself. I balancer while charging and discharging the pack. Anyway 2s i feel doesn't need much balancing. Since there is no cell inbetween.

It looks like this, so I don't really understand how the wiring should be.

Sorry for being dump.

so humble sia. U know lah i also not good at explaining.

To make things short. Normally it would be simpler when most lipo comes with balancer tab. so u juz plug in the charging lead from the charger to the battery and the balancer to the balancing tab.

So in the trakpower case u need to wire up the balacing tab to charging lead.

So in series; 2s
Charging lead 1(-) 2(+)
Balacing tab 1(-) (+)0(-) 2(+)

They have a special balancer connectors available for balancing TrakPower via the V-balancer. You might want to approach the new FP distributor for assistance.

Flightpower balance harness for 2S Trakpower packs

Hi Folks,

The Flightpower 2S Harness for Trakpower packs (Gold brick) will be available in our store next week.

This is the right harness for the job. See pic.

We will also be receiving all the lastest packs of various capacities in next weeks shipment.

[Alfie]

I think I get what you mean.

2 Positive Leads, 1 Negative Lead.

So there are will:

2(+): 1(-), also the wires will appear to be: (+)(+)(-)

Which one is the (Positive) wire that goes to the 2mm plug? Left or Centre?
Thanks for your help all these while.

U can't say there is 2 postive leads and 1 negative lead cos for 2s u need 3 wire in order to detect the voltage of each cell.

the black is more like an indication that thats the -ve for the first cell.
So the black -ve and the centre +ve reads voltage for the 1st cell
to read the 2nd cell the centre +ve now becomes the -ve and the 3rd red will be the +ve

I hope by now u know y the centre goes like tat. If still can't visualise try using 2 AA battery and join them in series, then ask yourself how u going to measure each AA battery voltage.

Flightpower 2S Harness for Trakpower packs (Gold brick)

Hi,

Great reply.

The Flightpower 2S Harness for Trakpower packs (Gold brick), part number TP2S-VBALH retails for S$ 6.30 each.

Actually the harness has 2 x 4 mm bullet connectors , one red and one black, these connect to each bigger connector on the trakpower pack. The red 4mm connector connects to the right and the black 4mm connector connects to the left, see pic below. There is another 2mm bullet connector which connects to the middle connector on the pack.

In a normal cell, from the red big connector to middle, you will measure 3.7 volts and from the middle red connector to the black you will also measure 3.7 volts. If you measure across both big red and black connectors, you will get 7.4 volts.

Caution, do not run you trakpower packs down below 6.2 Volts in normal use. Over discharging damages the cells and causes bloathing.

Gentlemen,

The TrakPower harness is available locally already.
We forgot to add it to the list previously. Sorry for that

Have a look here (see drop down menu at the bottom):

Ok, I think the better word for those wires will be black, red, red.

I think this is easy enough for me to understand. You've been a great help, bluesky.

Now, can I use my current charger; Duratrax ICE?

Thanks for posting the price.

I'm comtemplating on whether I should solder those tabs or buy the harness from you guys.
