How to charge LiFe rx batt that has no balance cable

I have an iMax B6 AC v.2 charger. I recently bought a couple Reedy '307, 250 mAh LiFe rx batteries that do not have balance cables. I have tried to charge the batteries on both the LiFe Charge (not Balance Charge) and Fast Charge programs and always get the error message "Balance Connect Error." My Charger manual says ther is also an error message "No Balance Cable Detected" and "... if your battery comes without balance lead, push enter to start." Pushing enter with the Balance Connect Error does not start the charging program. I think I'm getting the wrong error message, but have no idea how to get the right one. Does anybody have any ideas, short of buying a different charger, how I can charge these batteries? Neither SkyRC nor Reedy have responded to my inquiries to them.i

Thanks for any help you can offer.

What does it do when you push enter?

And you've tried pushing and holding for a few seconds?

Pushing enter does nothing. The error message remains, but nothing else happens. I've tried pressing long, short, and repeatedly. Generally this charger requires a 3 second push on enter to start a charging program; I have tried that too. No difference. Nothing happens.

Are you trying to hook up the brown/orange lead to charge? It's possible that the battery has a balance circuit in the pack. Normally, if you have brown/orange wires, the brown will be ground.

Damian Liu of SkyRC followed up on the question I left on their site. First, he said to go into System Settings in the charger and "Load Factory Set". See pp. 08, 17, Owners Manual. When that did not work, he said to go back into System Settings and progress through the menu to "Bal. Connection" and manually turn it off. You will then get a warning that it is off. None of this appears in my user manual, but the Bal. Connection menu item is immediate after the Load Factory Set referred to above. After successfully charging the battery, I disconnected it and powered down the charger, and then restarted it and returned to the Bal. Connection in System Setting; it was still off. So, I you need to do this, be sure to turn the Bal. Connection back on before doing a balance charge.
