I ordered 4 of these some time ago.
One was already faulty, one cell was empty and if charged couldn't hold the charge, it was replaced by HK.
Of the remaining 4, 2 have died in the same way. The cell's grew in size and I'm unable to charge them in a normal manner.
If you don't use the cells very often, don't buy them.
I have never had this before..

Don't buy these I batteries they are total rubbish. Purchased 2 of them both wouldn't charge above 78pcnt then both of them have puffed up so total useless. They were purchased for a large aircraft but wouldn't use them or recommend anybody this rubbish. They wre only charged at 1amp and never even got to put them in the aircraft let alone fly with them.... Sent pictures to hobbkking for warranty and just kept getting requests for pictures to be sent. Will never order any batteries again from hobby king

Mein Pack ist leider auch unbrauchbar geworden! Zellendrift und extrem aufgeblht, dieser Akkupack ist leider NICHT zu empfehlen.

My pack is unfortunately unusable! Drift cells and extremely bloated, this battery pack is NOT recommended.

Oh well, as others have found, 2 packs completely puffed while stored... I would have stayed away if I had read the reviews here before buying....

I use these packs as power for a high performance 2800 lumen, 32 watt bike light. One pack will run my light about 50 minutes. I've run about 15 cycles on both packs. The first 5 cycles I just topped both of them up each day after they sat overnight. I kept track of time to charge, each cells voltage, number of amp hours added and I measured each pack's dimensions. I found that if a particular pack had an unbalanced condition (more than .1 volt difference between cells after disharge) that over the next charge or two, that difference went away.

I drained both packs three times, down to about 1to 1.5 volts per cell. The Cellpro Gold 4S automatically did a Low Restore and put both packs back to normal. On Low Restore, with one of the packs down to 0.9 volts per cell, the Cellpro showed that 4.7 Ah had been added.

I also measured with calipers the starting dimensions of both packs. After 15 cycles, both packs are within 0.3mm of their starting size.

I did drop one of the packs on the cement floor of my garage. The force dented one corner of the pack and caused part of the shrink wrap to crack along the edge. Fortunately this has not affected the pack in any way.

LiFePO4 packs can be stored at 100pcnt charge. It seems that charging them, just to top them off is a good thing. In the beginning, one of the packs took about 3 min to top off after sitting overnight and

Just wooowww I heard about LIFO batteries but never thought how good are they first of all thanks for the super fast delivery for all my item from HK to United Arab emirates in a week! Just great.
Now for the batteries I tried them on my grasses summit brushed I put two of them and for 30 minute of full power playing always 2 wheels and jumping and hard
Play for 30 minutes first 20 minute then relax and after 3 hours 12 min. And the batteries were just as cool as I put them in the first place with no influtaion like lipos(although the temp. Outside in our area was 45 c).
My next try will be with my e revo brushless.
So my final thoughts 5 thumps for batteries type and power and prices and delivery. I will post some videos soon with my summit 2 wheels.
Thanks for your time and enjoy your time

I am using 2 batteries for 2 years on a Boomarang XL jet with Emcotec DPSI. It's perfect for receiver battery.

I put 2 of these in my starter box for my 1/8 nitro buggy. Used it for a whole 10days at Asian Champs and put back only 800maH after a full charge. No bloating no lack of power and super light! For 24bucks, hard earned well spent!
