Default Flightpower LIPO balance plug help?

Hey there!

I recently bought a used Electrifly PBY-Catalina ARF which was equipped with
a Flightpower EVO30 Premium 3S LiPo.

I have an iMax B6 charger-balancer, but I have a problem connecting the balance plug of my pack to the balancer.

Could you please help me? I guess I need an adapter/converter but I don't know which plug I have and what I need.

Thanks a lot,
Kostas1

Bad luck, it seems you have an old style Flightpower battery. I have copied this from their web site.
All balanced packs now feature the JST XH plug — the most common balancing connector in the industry.


Probably the easiest thing would be to buy another battery! I must have bought dozens over the years from everywhere and every one had a JST-XT balance plug fitted.
If you are up to soldering you can buy the plugs with short leads on them and you could replace the original non standard ones.

yes but I cann't throw in the garbage a LiPo pack,just because the balance plug doesn't fit my balancer.

The question is this:
IF I buy a JST-XH 3S plug should I be very careful with the polarity of the leads???

Kostas1 solution is probably the easiest

If you fit a new plug you have have to ensure the all wires are exactly to the same pins other wise it will never charge, or possibly wreck something. Also be very care only to cut, solder and re insulate one wire at a time. Touch two together and it would short out one or more of the cells. The current could melt the wire and possibly destroy the LiPo!

You mean that the easiest way is to buy the TH converter that is ready to use or just buy a JST-XH 3S plug
and
trim-connect the wires accordingly?

Congratulations!
Your Catalina seems to float slightly port (have to use the nautical terms!) wing down which makes the take off tricky. Is there a lateral balance issue? Sea planes with wing tip floats are much more sensitive to this than a land plane.
Not quite sure of your landing technique. Flair and just kiss the water? Even if it is just the tops of the waves!

Thanks a lot for your kind words!!!!
I haven't balanced the model laterally...maybe it's just the directions of the wavess??? :P

Hey there!

I just want to let other users of Flightpower packs,
about the connector I bought.

This is it: a 3S male JST-XH to female Thunderpower.

Nice, descent plug and cheap.

Greetings!
