Hyperion connection

[stevelawiw]

Am looking at connections and wiring etc. I'm going to replace the connectors that interface with the charger as they are getting a bit loose. I thought the resistance was too high. I let it charge for almost seven hours. I've attached a screenshot.

Well its not balanced or charged yet, so restart... Wait until IT stops!

It may take a LONG time before all cells reach 3.450v Plus or minus 0.003 of a volt. Once they do it will say charge and balance end. And sit beeping at you. Let it do that for a couple of hours. THEN its charged and balanced. Next time the balance and last part of the charge will take a just a few mins.

Ok, thanks I'll do it tomorrow. Off to the land of nod now...

LOOK at the graphs and voltages here. Charged to 3.600v

Look at the shape and balance at the end.

Also, I suspect you have missed a couple of bolts when tightening all those 6mm allen screws. A loose one or two will make balance and chargte take days and be very inconsistent. Go around all of them and tighten.

Everything you need to know when making or connecting lithium cells or balance leads.
