After market charger

[Thomas111]

What the best rate to discharge the battery at

 

[Thomas111]

Ok charger will only go from 2.0 down so left it on that setting

 

[Thomas111]

Well called yuneec UK they said send it back to them so it's away today so hopefully get a new one under warranty

 

[Thomas111]

Ok update sent the battery back yuneec UK sent replacement under warranty so all good

 

[Thomas111]

Ok while charging my 2nd yuneec battery today this has developed the same fault as the 1st one I just got replaced by yuneec what is going on here

 

[Thomas111]

Just found this on a site any members got 1 or used 1 now wonder what you would have to put ur aftermarket charger rate up to if 4 batteries on it

Stay away from the multi port charging boards.
They're bad news.
I have a couple and here's what happened to me....
On a multi port board, what one battery gets they all get.
I charged four batteries. My charger died on one leg (to much pull on charger) so all four batteries became seriously unbalanced on one leg. I spent hours trying to get all four back to a balanced charge that my charger could see and not give error warnings.
The boards are not insulated or isolated and if you get the board into some metal... a dead short is bound to occur.
My suggestion... stay away from the multi port charging boards.

Thanks jafo for that yes I will stay away from them that's terrible that these are allowed to be sold

 

[Thomas111]

Jafo at the moment I keep my batteries in the case with my Q is it ok or should the batteries be laying flat

 

[Jafo]

That's just fine.
After flying, give them time to cool before storing in the box.

 

[Thomas111]

Yes I leave them out the box till cool

I must have an iMax charger somewhere in my storage room. I used to charge my Align Trex 450 Pro V2 lipos back in the days...

 

[Thomas111]

Question on the charger it gives input charge rate now am I right in saying this should be set to 12.6 volts

 

[Thomas111]

Hi here is the instructions if anyone can help with my question

I have set the cut off timer to 1hr 20mins

 

[Thomas111]

Any help please

 

[Jafo]

Been away on Vacation...
I turn off the timer. I watch it enough it's not needed for me.
Your charger should taper off the charge as the battery fills up and should have a minimal trickle charge when it's done.
There should be no heat build up at all. If so, reduce the charge rate.
I start most of charge cycles at 5-6 amps and let the charger do the rest.

 

[Thomas111]

Thanks jafo For the 5400 yuneec battery I set at 5.4 and for the 6400 gifi power I set 6.4 that correct that way not puting too much in to damage

This guy ships to the UK.

Happy Hunting.


Added: If you don't already have them, you might need a couple of these too.

Not quite true. you will need to buy a second EC3 charge cord and a second Yuneec cable/balance cable.
The Venom Pro Duo comes with one EC3 charge cable and 2 balance boards.you need to supply the balance cables (the cable you use to charge the batteries with the Yuneec charger).

 

[Jafo]

I guess that's true.
I think I forgot about buying the other parts or maybe I already had them laying around.
Thanks for the reminder
