Any enerland cell based pack (ie, polyquest, polyrc, flightpower, neuenergy, hyperion, etc)

Maxamps (all)

Hi Linc, are Neuenergy Packs actually using Enerland cells? Note their capacity numbers are completely different to the ones listed on Enerland's website for their XP XQ cells.

I always thought they were enerland. They are assembled similar from the outside, and they definitely have tabs on each end, and only enerland and elite do that.

I have not pulled any neu packs apart yet, no dead cells so far.

In fact I have not dealt with an enerland based pack that had anything other than physical damage, no qc issues, tabs falling off or much else.

I did have one trakpower pack that smoked a bit during a charge, turned out a balancer wire must have been bad (maybe pinched and cut thru most of the strands?), and it got hot and melted the insulation. I popped it open and changed the wire out, no issues since...

Otherwise my experience with enerland cells has been great. I have made and reconfigured a ton of packs by them, with great results.

Surely they are great packs, but seems like there are more good cell manufacturers than just Enerland.

I just paid some small attention to the details, what I found is FlightPower, PolyRC & Hyperion's packs all have capacity numbers accurately match Enerland's cell series, say 30C XQ series, 700/1200/2000/3200/4500 mAh，or twice the number for a 2P config. But NeuEnergy has 800/1500/1800/2100/2500/3300/4100/5000, none of them match Enerland's cell.

Also there are some Chinese LiPo maker do their cell's having tabs on both ends.

Enerland do offer quite a few different cells. I have found that the 5000 30c cells are offered in different lengths, a short and a long. These cells are the same with all of the mfgs that offer them.

As far as the tab on each end goes, I pulled my first rhino pack apart last night. It certainly has the enerland style cell layout, but is assembled differently. None of the std enerland markings on the foil either.

Question time...

Who do these belong to? Real name is Michael Chin...



And the lower pack is a great example of a puffed cell. I do not think I have ever seen a cell that puffed...
