Smart 12V 150Ah LiFePO4 Battery with Bluetooth, LED Display Screen, Safety Switch and BMS, Perfect Lithium Battery for RVs, Golf Carts, Boats and Home Energy Storag

Had the 12v/300Ah battery for two months, here’s what I can report so far: Performance Capacity: This battery meets advertised capacity and current specifications. Testing I’ve been able to conduct include 25amp continuous load via a Rigol DL3031 electronic load, and a 2000w inverter (4000w peak) driving various loads in my travel trailer, including a 15k air conditioner. Using a Fluke DMM and clamp meter, I’ve seen 280 amps output. The BMS seems to work as advertised, and lives up to its beefy 300a continuous claim, and 450a (30sec) or 600a (5sec) peak are plausible. While I’ve not discharged beyond 80%, what I’ve seen suggests the cells are 304ah capable. I can only charge at 75a, and the battery seems to handle that no problem. The WiFi app and on-battery reported voltage is accurate enough, while the reported capacity percentage is a simplistic (as expected) measure. Overall, quite happy with its performance. Bluetooth: The functions of the app are somewhat limited, but intuitive and informative. There are two versions of app that work on iOS, powerQuary and CreaBest. Both provide the same info (total v, cell v, current, temp, alarms), consistently connected and reported measurements fairly accurately. Only issue is limited range - the case is 100% steel with overlapping seams, so with an internal antenna, no surprise there. Balancing: This version seems to only have passive balancing, which workes but is very slow. The same battery is sold in Europe under CreaBest and ShenTec labels, and those versions have a separate active balancing board. This battery has BMS provisions that would supply power to a balancer, and has threaded holes in the cell buss bars for per-cell connections. I’m looking into what it would take to add a Neey Active Balancer, which seems perfect for this battery. Design/Build First, my battery is more compact than the Amazon listing suggests, although still a brute. 243mm wide, 258mm high (248 if you don’t count the top handles) and 400mm long plus the terminals that project slightly. Mine weighed in at 72 pounds. The case is steel, well painted, with copious screws holding removable (but glued I’m told :) top and side panels. It’s not water proof, but then again, Im glad it’s not cheap plastic like most everything else out there. There’s no deflection when you press on the middle of the panels - this thing is a tank. The cells are pressed together by additional metal panels, stitch welded to the frame. The front display shows estimated capacity % remaining, voltage and amperage in tenths and internal temp (only in C). The power button lights when on, and requires a long press to shut off. There’s an Ethernet port, but no advertised use for it. My understanding is it’s actually a serial connection for factory use, YMMV. The power terminals are M10 (bigger than advertised) and solid. The top has foldable handles, which work well enough. I’d love to be able to remove them, but they’re bolted on from inside. They’d need to be, it’s a beast to haul around. If the Amazon and others pics of the guts are to be believed, the build quality is superb. Spoiler: They can be believed :). The cells look live EVE, but can’t confirm. The BMS is two boards, electronics with the controller, AFE, and connections, and a separate MOSFET board, with 58 of them (!) on a flat aluminum sink plate. There are no large gauge cables: all the current carrying is done by aluminum buss bars between cells (nicely made with expansion humps) and substantial insulated / tin-plated copper buss bars from cells to MOSFET board and terminals. Did I mention this thing is a tank? I haven’t seen better build quality - it seems it really is built for heavy duty. All the wires are indeed neatly tied down, the BMS is conformal-coated and well made; the whole thing is well put together. Value At about $800 (when I purchased), it’s not the cheapest way to get 12v/300ah, but I think it’s a good value. The only feature it doesn’t have is self-heating, but the high/low temp cutoffs work. It also doesn’t have the best weight/capacity or volume/capacity ratio, but the build quality makes it the kind of battery you keep, even if you later have to replace the cells. The customer service folks were responsive, and the warranty is the typical 5 years. Mine took a week to ship from CA to DC and arrived 98% charged and very well packaged (see pics). If you can handle the size and weight, this battery is hard to beat. I liked it so much, I purchased two more (my money) to finish my RV Pb-to-Li conversion.

Very well packaged and in excellent condition. The charger is robust and appears to be of good quality. The app works very well and shows exactly the same as the battery screen and some other functions. As soon as I have a chance to test it, I will update the information. For now I would buy it again.

I’ve had the battery for a few weeks now and I have had time to thoroughly check it out. I’ve had several email exchanges with customer support, both before and after my purchase. They always answered my questions within a day, often within a few hours. I chose this battery because its combination of features is relatively unique for a battery in the standard 100 AH size. Namely, it has more than 100 AH capacity, 150 amp BMS, built-in shunt with display, Bluetooth capability and on/off button. The battery arrived in a few business days. It was packaged VERY well. Nested sturdy cardboard boxes with two high density Styrofoam packaging layers. I verified that the battery will source 150 amps continuously for several minutes. According to customer service, it will maintain that high current till the BMS high temperature cutoff. The battery has a display, which shows battery capacity, voltage, charge/discharge current and temperature. I checked each of these with external measurements and found them to be reasonably accurate. The Bluetooth app is basic, but functional. I like that the battery has on/off capability. I verified zero volts on the terminals when the battery was “off”. My one complaint, is that I was not able to get the advertised 150 AH capacity. I was only about to get about 135 AH, but I decided to keep the battery because of its other features.

I purchased a 150Ah battery in December 2023. Within a few cycles it failed and the display would cycle between 100% charged and 0% charged. The company sent me a replacement battery and it failed after 7 cycles with a MOS State Charge warning showing in the app. The company told me this was due to a faulty core and sent me another battery that did the same MOS State Charge failure after 1 cycle. I own 2 other 100Ah batteries from 2 other companies. I use the same smart charger for all of my LiFePO4 batteries and the other 2 have not failed after more than 50 cycles. Now Hypery wants me to send all the failed batteries back to them before they are willing to refund my purchase price. Mailing the batteries back to Hypery to a CA address will cost me more than the purchase price. They do NOT honor their warranty and I would NOT recommend doing business with Hypery to any of my friends or family. I am very disappointed with how Hypery has handled this issue. I will be purchasing a 160Ah battery from Amped to replace the 150Ah battery I was trying from Hypery to power my motorized kayak. Do NOT waste your time and money by purchasing their 150Ah battery. This has been a very frustrating experience doing business with Hypery.

Have not had a load on this yet. Was 88% charged when it arrived. Charged it to 100%, and charge dropped to 92% a day later. Charged it to 100% again. Charge held 100% longer, but dropped to 96% a couple days later. Charged it again. Has held 100% so far since then (three days ago).

My BMS readout stuck. Customer service replied immediately with a resolution!

I bought 4 of these last year and they are performing flawlessly with my solar array. I decided to add another 4 to increase capacity because I was so pleased with the ones I got (and I added another inverter). The new batteries have sat for 2 months in an AC controlled space uninstalled and unused. When they arrived the built in gauge reported all 4 as 99% charge. Today I finally got around to install and found 2 batteries reporting 78% charge and 2 batteries reporting 0%. That is a lot more self discharge than I would like. They are on chargers now and seem to be taking a charge just fine, but I am wary of placing them in the bank. I will probably add the two 78% batteries now (once topped off) and when the 0% are fully charged let them sit a month or two and see how they do. So for now I have knocked 2 stars off my 5 star rating due to apparent quality control issues. If the recharged 0% batteries hold the new charge for a couple months then I may raise my rating back up. Again - the four year old batteries are still performing wonderfully. Just the newer ones are not doing as well.

This battery’s been working great for me. I have it them hooked up to solar panels, and power inverter running a RV works great and seems to charge up fast…. Had a problem at first but company took care of it for me thank you for making everything right! Good battery hope to purchase more soon

ok nente da dire se avre la posiblita di fare altri impianti mega scleri le battrie di queso veditore

niente da dire ok

Don’t buy this battery!!! I can’t say why because this was rejected on the original review (why?!)… but, please don’t buy this battery. I would have preferred to have provided more information.

Ich habe diese Batterie für festivals besorgt um die Autobatterie nicht leer zu machen. Habe 3 Lampen und ein Radio damit in Betrieb und dies funktioniert sehr gut. Wer mehr Leistung erwartet, muss natürlich auch mehr AH nehmen. Für mich völlig ausreichend und mega entspannt, da ich keine Angst mehr haben muss, mein Auto nicht mehr gestartet zu bekommen. Demnächst noch paar Photovoltaik Panels dran und es ist perfekt.

Der Akku wurde schnell geliefert und war leicht in Betrieb zu nehmen. Ich nutze den Akku als Speicher für meine "Camping"-Solar Module, die ich auch zuhause auf dem Balkon betreibe. Ich denke in drei Jahren kann ich dann mehr sagen ;) Was mir nicht gefällt, ich möchte eine frei formulierte Frage an den Hersteller bzw. Lieferanten schicken, weil ich eine Frage habe, die nicht zu den vorgefertigten "Hilfeseiten" passt. Das wäre relativ dringend, ich würde evtl. einen zweiten Akku kaufen, muss aber vorher noch etwas abklären. Schade, dass das so schwer zu finden ist. Oder ich übersehe da was? Aber wie gesagt. Der Akku selbst ist vollkommen okay und wenn der auch so lange hält, wie beschrieben, ein sehr gutes Preis-Leistungsverhältnis. Nachtrag: Ich habe eine entsprechende Möglichkeit gefunden, direkt eine Frage zu stellen. Vielen Dank, so passt das alles.
