Default Newbie Needs Some Balancing Help

Hi, I have Losi 2.0 E and run a 4s battery in it. When I bought it I also bought a Venom balance charger and venom battery. I had to change the connectors on the battery to Losi style to match the plug on the ESC . So far so good. Well, I bought a Losi battery now and the balance connector is different than the Venom charger balance port so I can't balance it. I heard about balance boards but have't been able to find a Losi to Venom adapter. Any help is greatly appreciated.

And the charger is JST-XH.

So you need an adapter to go from JST-XH to TP.

Thanks guys. I found one on-line. One other really basic question on charging balancing. Should you fully charge your Lipo and then balance or balance and then charge?

The best way is balance charging - balancing while charging. The Venom charger is able to do that. That way you wind up with a fully charged, balanced lipo in the shortest time possible. If you balance after charging, then all the balancer is doing is lowering the cells to the min voltage indicated by any cell - that costs you some lipo capacity (run time). You lose any benefit of balancing if you do it before charging.

Balance charging is the way to go.

So you need an adapter to go from JST-XH to TP.

Duster I just got this connector and it doesn't work, on either the battery or charger.

Post the link to the adapter you bought - I assumed that bohdi was correct about the TP connector.

Does it not fit on either the charger or the lipo? I know the charger is JST-XH - it should fit on the charger.

Just to make sure we are on the same page, I have a new Venom Pro Charger that uses a 5 way Balance Block and am trying to mate the balance connector on my Losi LOSB9864 14.8V 4S 25C to the balance block. My SMC battery balance connector hooks up no problem

SMC uses JST-XH balance connection per description here -

http://www.spcracing.com/index.php?categoryID=11


Losi supplies no info on teh balance connector used -

http://www.losi.com/Products/Feature...rodId=LOSB9864

There are only 4 balance conns in use - JST-XH (Align ), PolyQuest/Hyperion, Kokam and Thunderpower.

I am correct but the JST-XH has the Align connectors and you will need the TP adapter of some kind to hook up to battery if it actually plugs into your charger.

I bought the Align EFLA229 adapters.
You will only use 5 of the six pins on the adapter itself, just make sure you match the red wires on battery and the adapter. All adapter pins will not be used (1 extra and not used) but all the pins on the battery will be connected.

I use the Hyperion charger too.

Wldmoose - show us what you bought online that doesn't fit. I can't find an adapter.

For balancing using Venom Pro, you plug the balance connector into the side of the charger. If TP is correct, you need something like this -

http://www.hobbycity.com/hobbycity/s...idProduct=7349


I have an Accucel-6 charger that does my 2S lipos - it has the balance conn built into the side like the Venom charger does. This lets me charge my Flightpower pacs - the harness plugs in to the side of the charger in the 6S slot, then to the adapter board.

OK, I found a manual for the Venom Pro and I'm wronmg about it having multiple connections built into the side for balancing - it has a single connection and comes with one adapter board for JST-XH balance connection. Now I'm not sure if what I linked above for an iMAX charger will work or not.....

I just spoke to Losi customer service (after almost 45 minutes on hold) and they said it is a TP connector
