HV LiPo's How to Charge

[White_Crow_G]

Hi Everyone.
Well, my question is as simple as thread name.
How to charge HV batteries.
i've just received a pair of HV's. my Hota D6 pro is charging to 4.2 v/cell by default.
It doesn't have any HV charging program
Should i change voltage to 4.35 v? is it safe enough? or maybe i should change it to 4.3v or 4.34v?

Thanks mate. never check this menu as it was always just LiPo's.
Will take a look this evening

I don't charge my HV packs any differently than standard LiPo packs.... 4.2v/cell and done. I only bought LiHV 2S packs because they were on sale and were in the capacity range I was looking for. Will the life of a LiHV pack increase if a person does not charge to 4.35v/cell? I don't know. Lots of debate/testing done on voltage dropping on LiHV vs. LiPo cells.

Probably just a marketing thing to make packs more attractive.

My LiHv packs by SMC outperform ace gens. CNHL’s. I have a pair of 11200 mah LiHv ‘s for my boat. Night and day closely compared to 10K mah lipos. But I noticed the real difference in my speed run car. 105 with 27T gear and 15000 mah 4S bricks. Swapped out the batteries and hit 113. 114 with a 32T gear. 124 with the LiHv. I could just be lucky but I really enjoy them. Shawn Marsh. Aka: vwturbowolf turned me onto Onyx batteries. He’s the fastest man alive on a single motor. 203. hes fast.

I didn't even think about doing speed runs or drag racing. That part of the hobby doesn't pass through my head most days. Speed runs would probably be the only time that I would charge up a LiHV pack to its "max".

I'm not totally sure of your situation on how/where the batteries will be used, but if racing... gotta check them rules. If just general bashin' session and lookin' for that extra little zip... do whatcha gotta do.

that'll be racing.
just bought 2 packs of 9k HV's for this. if i get it right i can run then at normal voltage and they will be fine.
i'm not that super fast racers who will see benefit from +0.001v ))

The difference is SUBSTANTIAL..

Are we talking about the life of pack, voltage dropping, or both? I was more inclined to believe a LiHV battery would have a more constant voltage for a longer period of time, but only if you were to be "fully" charged (4.35v/cell) a pack.

I’m talking back to back comparison vs standard LiPo. More power, and longer runtime “apples to apples”.. No clue on the longevity/life-span, as a few of mine are still going strong as ever after almost 4yrs now.

So are you charging them to 4.35v? and 3.85v for storage?

4.35V to run, and 3.8 storage.
