LIHV question
 

What is the correct LIHV storage voltage? My charger has an option but it seems high.

Like charging could I just use the standard lipo 8.4v storage discharge?

I searched around and couldn't seem to find anything real definitive. (maybe I just missed it)

Same as a normal Lipo. I think the hv Lipo thing is kinda a gimmick. Pretty sure standard lipos can be over charged too. It's within there specs. Airplane guys have done it for years. So your standard Lipo is let's say 4600mah. They just call it hv 5000mah. I think it's like adding 400/600 mah. But whatever

LIHV's have 3.9v per cell as opposed to 3.7v of a normal lipo. I would think that a safe storage charge would be the same a a regular lipo

How about charging lihv packs beyong 4.35 volts per cell, say 4.36 or 4.37 for a little extra power?

i wouldent do that. The 4.35v is high enough

The newest iCharger software can go up to 4.4v per cell. I doubt they would allow that if it completely ruins batteries and causes fire.

On some older chargers that aren't LiHV capable the storage voltage is actually too low. My nosram LiHV pack says 'dont discharge below 3.3v/cell' whereas normal lipos have a 3.0v minimum

Uh, I wouldn't push it, I've seen at least 3 batteries catch fire during a race or at a pit table. I am positive it was due to over-charging. Sure, some guys will push it and try to get that extra punch from their battery ...but its a serious risk. Its pretty obvious when a battery goes up as to why.

Did you set up these peoples chargers or check to see what they were charging to? Were they HV batteries? How old were these batteries? What was their IR numbers of the packs? How much capacity had these packs lost?

​​​​Pushing the limits of battery technology requires responsibility and a very good understanding of what to look for to stop using the battery before it goes into thermal runaway. Some people have a difficult time with attention to detail, these people do not pay attention to the signs to stop using a battery.

If these guys have older packs and got a new high power charger to try to be competitive, then yeah high power charging is going to be dangerous.

Here is new research that shows occasional high current cycling is good for the battery.

I presume you mean LiHV? If so, yes the newest software creates a LiHV profile, and let's you set the end voltage to 4.4v per cell.

The newest icharger software has lihv settings. I believe its version 2.18. When you go in to the battery type, it'll have lihv as an option and allow you to set the cutoff voltage to 4.4v per cell.

Found the LiHv settings...guess I just had to look down the list more.
