Stop making biased reviews of these lackluster products just to make a buck and get free swag. This battery is super cheap only because it is unremarkable with what must be average cells based on your testing. A brand new battery with decent LiFePO4 cells should have easily pulled rated capacity or more without needing to get into the absolute top/bottom of the charging curve. There is no energy to be gained really. Nobody wants a 15x cell battery that doesn't conform to standard inverter charge/discharge profiles. A no frills battery like this should be 3U not 4U height, saving physical space in a rack. Yet another TH-cam channel I have always liked that I am about to permanently block. The TH-cam platform from top to bottom has become so unethical and/or corrupt. Manufacturers are having a field day with how easy it is now to get subpar products represented to the public as something worth buying. So many channels selling out, sacrificing their credibility and integrity.
@@BeatTheBush You obviously didn't read or you understand what I wrote. If you knew anything about LiFePO4 charge/discharge curves (which you should as a guy doing battery reviews), you would know there is very little available energy to be gained at the top and bottom of the curve. Regardless, GOOD new cells would have tested over capacity despite not quite being charged in full. The .4V at the top/bottom of the curve in a 48V battery would have added very little energy...marginal at best.
Hi, was wondering, apart from voltage difference s, what are the pro and cons comparing this battery with the ones that you reviewed several videos back? (The ones that have carry strings attached).. assuming they're both on the same voltage..
If you have 48V (16 strings) on both packs, it's better to go with a server rack since it has battery balancing built in. There's less cost of cables, less fuss and assembly too.
There are two things you sort of allude to in your video, but never really discuss, with any specificity. These batteries have one less cell, which means the voltage can sag below 48v (which you noted), and due to charge parameter limitations, you accepted that you are getting 3% less capacity. However, you're also getting one less 100ah cell, or 1,280wh less capacity, since it does not have 16 cells. Now, that battery does come in at a competitive price point, even after you take into account the reduced watt-hour capacity it has. The problem is that it doesn't adhere to the industry standard of 51.2 volts, nomimal, by using a 16S design. Many folks are "Weizely" staying away from these 15S batteries, for that reason.
Both 51.2V and 48V batteries will drop below 48V with enough discharge. 40V and 37.5V respectively. There was an issued with charging to 100% using my inverter since the voltage setting was in increments of 0.4V. Certainly, if you build a brand new system, I wouldn't go with a 15 cell but it's interesting to see.
@@BeatTheBush No, no it's not really interesting to see a battery that that doesn't' conform to standard inverter charge/discharge profiles. Only reason to review this is to make money and get free stuff. Hench the affiliate links for garbage.
@@BeatTheBush - I'm not talking about the range of voltages throughout the discharge curve. I'm talking about voltage sag under load, which is completely different, although the two concern do intersect. The main takeaway is this battery is not following the industry standard and that makes it a bad choice for a variety of reasons.

Well said
The reduced capacity is due to a 0.4V charge difference due to my inverter since some parameters did not work well with a 15s configuration.

Fantastic review, i liked and subcribed, and will reccomend your chanel❤
awesome video! what kind of engineer were you in your professional career? An electrical engineer?
Electrical.
What about battery catching on fire is this one of them?
nah, that's Tesla
What do you think robinhood 3 percent cash back credit card?
Stupid question
It's great, video on this soon.
