new guy here
 

Got a duo and when i go to charge or balance my 3s a123 it says output circuit problem??? Ive never used a lithium charger but im pretty sure every thing is hooked up right like balance taps and its set 9.9 a123 2300 mah. This is frustrating me because i ordered this charger from bishop power products and i received it when troy was still working there. I hope he didnt send me a broke charger in a new box. That guy had some issues cause he sent me the wrong charger the first time and i had ship it back and wait another month to to get what i got now and its not working. I hope its something simple. Please any advice helps . thanks

make sure you have the pack hooked up to the output that you have all the settings set for. Sounds dumb but I've done it, had a bunch of packs and adapters sitting around the charger and grabbed the wrong output connector. Now I make sure I have a clear area.

I do and it still says output circuit problem.lol

Try it without the balance taps connected, and check the voltage of the pack/cells with a multimeter, just to rule out a bad connection inside the pack.

Why does the duo turn off when i unplug the a123 balance conecter?? The charger wont even turn on when i plug my nimhs in . I dont understand how im supose to chrge my nimhs if it wont turn on without a balance tap?? I dont have balance taps on my nimhs. Am i missing somthing ? I have the power supplly hooked up right.

oh ya and the firmware on this is v1.5. is there somthing wrong with that firmware? i think this was one of the first duos ever made cause it didnt even come with directions.

You need to upgrade to 1.7. That's an old stock. Hopefully it's not broke.

What do you mean by old stock? just curios.

The new ones came with V1.7 but you can update it to v1.9. You You'll need to buy the wires in order to update your charger to the newest firmware.
