I re-read the description section under the battery and saw the last line regarding to achieve peak performance charge these packs to 4.35 using a Li-HV charge. I have been charging my current packs to 4.35 in Lipo mode using a iCharger 406 Duo…. Ooops. Is this possibly the culprit that has caused my batteries to puff a little??
I should plan to use the Li-HV setting to charge the new packs, correct?
Should I use the Li-HV mode for storage and for discharge also?
I have been charging these at 3c and discharge to storage at 10a.
I use these in my Tekno ET410 baby truggy. We have a 10.5 blinky class we race in. I have plenty of power, should I limit the charging to 4.21 per cell and just use Lipo (or LiHV) mode to get a little more life out of these or is 8 months a good life time for a performance battery pack?
Thanks
You didn’t specify, but if they weren’t 7.6V packs, the short answer is... “likely?” - I’ve seen so many warnings about not charging 7.4 2S batteries to 4.35/cell that it’s probably with good reason. That being said, not sure if that’s a “Pro tip” to do that, but it’s a known fact that you shouldn’t overcharge LiPo’s beyond their rated Max voltage peak. I personally wouldn’t do it. Heck, still being new since getting back into the hobby, I’m hesitant to “train” LiPo batteries, even though I know full well the advantages of minimizing iR in batteries from the old NiCd/NiMh days.
