Hey Guys. I'm looking for some advice about my charger.

Today I left the charge-leads and balance-leads to my 10S pack connected to my Hyperion 1420i Charger, while disconnecting the input to the charger.

Very stupid.
Also the manual states that this is not a good thing.

Looks like the charger on itself is not affected by this mistake.
Unfortunately the (UART via USB) connection to my computer does not work as it should anymore.
It looks like it's constantly reconnecting. Sometimes I get some data, but most of the time it hangs.
Before this mistake it worked flawlessly.

Can anyone point me in the right direction, as to what could be defective in the charger?
Did anyone make the same mistake, and were you successful in repairing it?

I think you're right. I just bought one on eBay and I'm very happy with it.

Curious to see if any one is still monitoring this thread. Y'all seem like a friendly bunch. Please forgive me for not being able to search through the whole thread to see if a response maybe have already been given. Hoping one of you fine gents can just answer this for me. I have 3 6s lipos (22.2v) at 5000 ah. Can I charge all three at once with just one balancer.If not can i eliminate the balancer and use a different charging method ie pb or some other setting that doesn't require the balancer. I have two 12 v supplies running this unit. It has become quite a pita to charge these packs separately. Thanks so much and sorry for necroing an old thread

yes as long as the batteries are the same voltage when connected together. You need to make some sort of 3 way connecter to parallel all the batteries and connect all the balance connecters together.

They also sell a parallel balancing board (about 10 dollars) that you can use. Once all the batteries are connected together the charger sees one big battery and charges appropriately and keep it in balance.

also, while i was charging 2x 1s 60p blocks, i piggied another 10p block on with aligator clips. all seemed normal for a while i went downstairs to wach a movie :)
came back to notice the aligator clip leads were burned through.

looks like got hot and shorted where they overlapped..
why the hell would so much current go to the 10p block all of a sudden, maybe they have internal short??
i think their voltages were similar to start, but after, the 10p was drained to 1.8v??

just an update: i discovered by accident that i can charge the necropacks in "store mode" until they reach 3.6v or so, then using normal charging for the rest...now i have to find out how to enter store mode, as i found it by accident when pressing the buttons.. :)
