I agree. I think that not having 2C labeled on the pack says it all. If it was capable of 2C charging rates, they would have pasted it all over the package and battery as well as bold print on their website.

I sent them an email, but they're probably swamped during this time of year. I'll call Monday.
Thanks!

If the rate is too high for the pack/leads/ ect. You will find that a very large portion of the charge is done in the cv stage (at full voltage with tapering current) It is possible to use an entire cv stage (no cc stage) if the current is too high and/or the resistance is too high. Especially if the pack isn't discharged all way.

cv= charge voltage?
cc= charge current?
Is that close?

cc/cv routine
 

Most lipo chargers use a cc/cv charge routine

cc - constant current (up to the max voltage) then
cv - constant voltage (current falling off until full)

Cool Gulio. I'm learning alot. Thanks!

I have a Hiperion 720i. This charger should pick which method (cc or cv) or combination of both to use on its own depending on the internal resistance, voltage,and mAh capacity of the battery. Is that correct?

Lipo charging protocol calls for both CC/CV. Lipo's state of charge and the selected charge rate impacts how long it spends in the CC mode. You won't find the option to select one or the other. Charging thru main power leads, I've never seen a lipo charge start anywhere but CC.


Some charge modes like FAST lipo charge mode shorten the CV mode (or do without it) for a quicker charge.

Thanks for the detailed picture of how all this works and calcs out. It is much appreciated.

Here is the answer that A-main sent today on the original question.

"Thank you for contacting A Main Hobbies."
"Hello David,
well the manufacture says you can, and the size of wire on the pack will defiantly support 4 amps so you should be just fine :)"

I guess I'll try charging one at 2C (4 Amps).

That would be good enough for me......

Yeah me too. I was glad to hear the news.

I'd check the 1st time charging at 2C that nothing was getting warm (wire and lipo), but I doubt anything will.

After than 2C would be SOP.

"SOP" ???
I've got some fireproof blanket material that I use for welding. Thinking of making a quick bag to put it in. Maybe use some small nuts and bolts to stitch it together.

Sorry, SOP = standard operating procedure....

alright made the makeshift LiPo bag. Gonna charge at 2C tonight. Hope I don't burn down the Christmas Tree. LOL

Would you do a favor , please?

If you can notice at what point the pack reaches the CV stage of charge 4.2 volts per cell.

I'm curious as to how much portion of the charge is done at reduced current , it will imediately start to reduce current from the setpoint. It would be nice to know how much capacity or percentage is added in the last stage of charge.
