Hyperion charge error

[KartRacer]

I am trying to put my truck Lipos on my Hyperion charger. They are 2s 65c. When I connect them and try to charge, discharge, or store charge. I get an " too high output voltage" error. I have tried several times with no luck. Any idea what could be going on?

Are you sure you are using the correct board for your batteries

I think the problem is the two cells are to far out of balance. I have the same problem with my nano tec (crap) one cell on my 5s pack is always low after a good thrashing and have to charge on my astroflight where i can crank up the charge rate manually for 15 min then back on to the hyperion to charge and balance, and all is good........... so far!

Is the charger set to charge 2S?

[KartRacer]

Thanks for the responses.
The cells Re balance as I have been using a onyx 245.
The balance board is jxt for two cell.
I discharged the batteries on a separate discharger to 3.5 per cell and tried the Hyperion in all modes. I continue to get the error. The batteries charge fine on the onyx 245. I want to use the Hyperion because of the storage mode that is not available in the onyx.
Also plan Ed to sell the onyx as it is not needed.
Any help is appreciated.

still seems like the balance board to me what brand of batteries are they?

Well you are probably correct.
I just looked at the boards are there different kinds of 2s boards? The onyx board is an electrify the cells are integy.
The Hyperion is a just with 2 s port.
They probably offer an additional board that I don't have.

My guess is it takes a jst-xH board same as most HK lipos and that board does not come with the Hyperion normally

Well I won't be buying anymore of those batteries as I buying the Dynogy's from MarkF so maybe I will just hang onto the onyx 245 until they die.
Thanks for everyone's input!

Oh, in that case I'll get a couple of them.

just make sure you get teh correct ones for the charger you might need them for the other batteries also. Not sure what balance tap Mark uses

I have the tap for mark's , charging my 6s Dynogy's, they came with the Hyperion. I had these 2s before I got into FE.
