Smart 12V 50Ah LiFePO4 accu met Bluetooth, LED-scherm, veiligheidsschakelaar en BMS, perfecte lithium accu voor campers, golfkarretjes, boten en energieopslag voor thuis

Item was veel te lang in transit en de leverdatum werd lang en langer, elke keer zelf navraag moeten doen voor updates en elke keer ander excuus, dus gecanceled...

niente da dire ok

Had the 12v/300Ah battery for two months, here’s what I can report so far:PerformanceCapacity: 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/BuildFirst, 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.ValueAt 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.

I purchased four 12V 100 amp hour and placed in parallel charged by 600watts of solar through 40amp hybrid (wind/solar) controller NO ISSUES and works perfectly one year later! Price creeped up since then but quality is amazing.

Excelente terminado y calidad, cumple con las especificaciones. Volveré a comprar próximamente. Me ha funcionado de maravilla.Actualización: ha funcionado muy bien la batería. Pero han subido mucho el precio. Un 35% más lo que hace que salga del presupuesto para adquirir una más.
