Very good shape, being taller than usual, and taking less floor space.
This monster, having so little foot print, has enormous amount of juice. Over 4kWh!
App is showing right amount of % left in battery. I would give 4,5 star because 3rd party software didn't work with this BMS and humsienk own app is lacking advanced mode to see more info and statistics. Like cycle amount. But for casual use, it is enough.
Very highly recommend so far.
Replaced 4 12 volt lead acid batteries to the 12volt 100ah lithium batteries. Night and day difference.
Let me start off by saying this battery is huge in a good way. 110lbs (640ah) is awesome to have the capacity. If your running just one in a 12v setup or 4 in a massive 48v setup. The capacity for the price is hard to beat
The build quality is excellent also

Only had it for a few weeks ,but so far it has been Great,love that on the app I can see how well each cell is balanced,as well as the state of charge and discharge
Had a small problem but customer service took care of it for me other than that excellent
I bought this to properly charge my batteries on my boat. The boat’s inverter/charger system does not have a profile for new LiFePo batterieS so the batteries never get properly charged. If I want my batteries completely full before I leave the dock, then I use this charger to do a proper final charge.
I added the 300 Ah battery with Bluetooth to my boat’s house battery bank, 3 HumsiENK 200 Ah batteries. I never knew how full, or empty, my batteries were. Now I can look up exactly shat my battery bank is doing. How full it is, how many amps are going in or out, and I can disable the new battery’s charging or discharging. So I can cut my new battery off from the other ones with my app, so it can be a backup if I want to be careful.
I will never buy a battery without Bluetooth again!
This seems to be a very Good Battery.
I have had very cloudy skies since I installed the
battery. But seems to charge faster then the other two batteries beside it.
It has been working Flawlessly since it was connected to the system ten days ago.
I am Happy with its performance at this time.
I purchased four of the batteries, 12 V eight amp for a 48 V scooter and they were so light. It was like I had no batteries at all. They work great no issues at all. I will definitely advise anyone looking to purchase to give these a try.
Formidable batterie.
Bien conçue, n'affiche que 0.024v de différentiel entre les cellules.
Ce qui est exceptionnel pour une batterie de cette puissance.
Excellent rapport qualité/prix, livraison rapide et prix imbattable.
Vraiment, je recommande vivement cette batterie.
Great product & well made.
Lieferung dauerte etwas lange, aber sonst sher zufrieden! Batterie schaut gut aus, lässt sich mit Handy verbinden, alles super! Bin gespannt auf Langzeitergebnisse

Finally got a chance to use our rv and came away happy with the battery we install this year. It is and does what was promised Bluetooth work great and does everything I need. I received and charged the battery a month before using it and it stayed fully charged.
