Hope you get a good batch
at that price itâs worth a testâŚ
I can tell yaâŚthose HK graphenes are far from grapheneâŚ
The original batch of HK graphenes weâre flat a123 cells and weâre a lithium chemistry. They had an ok lifespan for cycles and thier IR was that of a regular lipo after about 15 cycles. after about 80 they were at 40+ mohm/cell
Iâve had zippys, nanotechs and bolts last longer.
snake oil?
Edit: I got zippy flightmax am i good?
Yea. Iâd stick with the bolts or or nanotechs from HK if I was getting lipos
Honestly bolts are my favorite. They are LiHV but if you charge them to lipo voltage (4.20/cell) instead of 4.35 they last arc ages
Edit yes zippys are good to essentially the same as nanotechs
I will most likely yet them next,
Also I will Charge my Lipos at 4.10V that good?
Nah charge your lipos to full unless your worried about braking(vesc overcharge cuttoff). Lipos arenât damaged over time by top of charge like like Li ions. The end discharge is more important for lipo(3.65/c cutoff at the very lowest) if you want long living lipos, and donât leave them full or above storage (3.85/cell) for longer then 48 hours
you lipo lovers charge to 4.2 and discharge to 3.5 we li-ion lovers charge to 4.1 and discharge to 3.2
meh
3.5 on a lipo is damaging⌠Best practices with lipos is stop at 3.7⌠3.65 is where balance starts to drift, 3.6 absolute lowest.
Liions have a wide range depending on cell quality and current being pulled
Good Advice I would of set 3.60v cut off But this makes me understand what is most important
3.7v I could do because i bought more range than i need
EDIT: 3.75 Overkill?
ah yea. the exact reason iâm always sticking to li-ions
lemme just tell you that 2.2v is DEFINETELY not safe for lipos. ask me how I know
Hahahaha nope itâs not(2.2v)⌠lipos are great if you treat them good. Iâve got lots that are years old with almost 1000 cycles and under 10mohm IR⌠itâs all how you treat them
4.15-3.7v is my window of use.

Looks amazing
Go Li-po!
my lipo setup was disgraceful lol.
18 hours to charge both my 3s 5ah Zippys, held to my deck with sheer metal, no voltmeter, batt cutoff set to 0v in vesc. âiâll just go home when it starts slowing downâ
Ha. Fire skating
You should be in jail for what youâve done.
Did they puff?
ever roasted a marshmallow? thatâs what they look like now.
they wonât even short anymore cause the voltage is so low
Hey if you ever puff⌠Put it in the freezer after you know itâs stable⌠itâll shrink the puffâŚthen slowly recharge it.
Learn your lesson and never over discharge it again as a 2nd freezer treatment probably wonât work lolâŚ
nope! charged on my back porch overnight
some would call me a genius
