PUPVWMHB 12.8V 300Ah Lithium LiFePO4 Battery With Bluetooth, Smart 200A BMS, 3840W Rechargeable Lithium Iron Phosphate Battery.Max Load 2560Wh .for Solar Energy Storage,Backup Power,RV,Camping

I bought this battery to replace the 2 deep cycle 6V lead acid batteries we had in our RV, (which were actually more expensive than this and only lasted 4 years). I also installed a Victron inverter, and I couldn’t be happier! No more need for a generator! Our first camping trip was for 4 days, and we never had to charge the battery. That’s making Coffee, watching TV, running the lights, microwave… At the end of the trip, we still had 30% left in the battery. The build quality is great, and I love being able to monitor the battery in real time on my phone. I can turn things on and off and see how much power they use. The next purchase will be a couple of solar panels and an MPPT charger for complete off grid camping. If you’re on the fence, pull the trigger! This is a great battery and very good value!

I bought four and used for a small off grid solar system. I’m pleased with them so far. These batteries are powering an 3/4hp well, a golf cart charger, ebike charger, and small electronics. All batteries came charged and in good working order. I appreciate the compact size but I don’t know if the size reduction comes at a cost of losing efficiency compared to the larger lifepo4 batteries. I’m pleased with the purchase and would buy them again. It is my understanding that when using batteries like these it’s worth noting that only half of the amp hours are considered usable. If that is the case, these batteries are just over 150 usable amp hours. Still good in my opinion.

So far this battery is performing as expected. I upgraded my 100ah to this one and like the fact that I'm not running out of power in the middle of the night for my propane heater. It lasts throughout the night with moderate use.

Initial Charge takes "Forever", but Awesome Off Grid Power. I have a 200w Solar system, to keep it charged, and a 30w Solar panel/ system for continuous/ trickle charging. The "App" to monitor activity, is mostly in Asian. Language. Customer Service is usually 72hrs to 4-Days to respond.. But they do usually give several options.

This appears to be a great lithium battery. I bought the 300 AH mini for a solar inverter project. I really like the size and weight of the mini and it seems to perform just as well as the full size. It all had to fit in a compact box shown in the pictures below. The blue tooth connectivity works great and allows you to see full status of the battery including individual cell voltages, load/charge currents, and BMS Mosfet temperatures. It even gives the estimated time left on the battery based on load and the estimated time to charge. I like that it has a 200 amp BMS as some large batteries only have a 100 Amp. I only have a 1500 watt inverter but I plugged in a hair dryer and the battery performed flawlessly delivering over a 100 amps of power. Bottom line, I just bought to two more for another project.

I purchased 2 of these to replace my failing RV house batteries. I monitored them to make sure they would not catch fire or blow up. The batteries charged erratically and did not stop charging when they were reporting full. In fact they were charging at over 400 watts at over 105% of rated capacity. This could lead to a fire or explosion. The batteries do not match well for RV parallel setup, as one would continually discharge under load, while the other would continually charge under the same load while the solar system was charging at the same time. One battery was at 30% charge, while the other was at 75%. Last of all, you must have internet service to control them. While camping off grid, we needed to use the microwave, so I started the generator. The batteries were low and drew erratic power from the generator so much that it shut down while also running the microwave. Being off grid I could not stop the batteries from charging so I could not use the microwave. I also noticed that if I stop the batteries from charging they will not deliver proper discharge current so that my inverter would not output power. The description for these batteries on Amazon clearly states that they are for RV's. If you use them in an RV you may not be able to use your microwave at times, and you will be taking a fire or explosion risk. The main reason for RV fires is electrical issues. I complained to Amazon support after the seller would not or could not address these concerns. Amazon promised to file an A-Z claim and promised that I would get a refund. A few days later Amazon sent a message that I would not get a refund and that I should contact them. I contacted Amazon via phone and was told they would file an appeal and that I would get a refund. Today I got a message from Amazon stating that this case was not A-Z compliant and that the case is closed. If you purchase from a 3rd party vendor from Amazon, be aware that you have no protection. The 3rd party vendor can make any claim they want and if their product does not measure up, too bad. It is better to purchase from Walmart where they refund without question. I plan on doing more shopping there and less from Amazon.

So far I am very pleased with this 300AH battery. The quality appears top notch. The post bolts seem excellent. The values/rates i’m seeing for charge and discharge seem perfect. No issues with the safety features, but glad it has them and I am really enjoying the mobile app support. I hv a 200 W solar setup with 300 ah battery and 2k pure sine inverter. Based on my region and access to sunlight, I’d like to purchase another 200 W panels (400 w total). Currently I only get about 8-9 amps max for 2 hours, so my charge rate for this giant is roughly 10-15% a day. I’ve set this up in my shed and tested running the shop vac and saw for an hour. Everything is working well together!

Put it in my camper and have never run out of power.

Sehr guter Akku

Ottimo prodotto ne comprerò altre due

Got 4 of these these in the spring of 2023 for my RV and have used them for a season so far. They were measured and provided the advertised capacity at the rated voltage without issue. They are a significant step-up from the 4 flooded lead acid batteries I used to run in terms of capacity, charging and their ability to maintain a constant voltage until they are drained. Their light weight also makes them sooo much easier to manage during install.

Wer etwas recherchiert wird feststellen, dass 170 Ah eine ungewöhnliche Größe ist. Dabei aber von der Bauform kompakt, so dass sie z.B. wie in meinem Fall noch unter einen Sitz im Van passt. Geliefert in stabiler Verpackung. Etwas merkwürdig ist, dass der Aufkleber mit den Leistungsangaben in meinem Fall händisch mit "170 Ah" beschriftet war. Nach nunmehr 3 Einsätzen kann ich aber bestätigen, dass die Angabe stimmt. Die erste Ladung (Lieferzustand exakt 50 %) war problemlos. Alles lädt bzw. entlädt unauffällig. Die App ist sehr rudimentär. Es scheint, dass weitere Funktionen möglich sind oder sein sollen, aber bei mir ist ein Großteil der Funktionen nicht aktiv. Das wichtigste geht aber: Ladezustand in %, Spannung gesamt, Zellspannung als Durchschnitt, Stromstärke in A (Entnahme) und Leistung in Watt). Hin und wieder kann man auch grafisch den Zustand jeder einzelnen Zelle sehen, dass funktioniert aber nur random. Wenn nur geringer Strom entnommen wird, dann ignoriert die App das und zeigt es nicht an, z.B. Entnahme kleiner 2A wird nicht erkannt als Momentanleistung. Etwas gewöhnen muss man sich an das Koppeln via Bluetooth. Rot heißt koppeln erfolgreich und nicht, koppeln gescheitert. Wen all dass nicht stört, hat eine simple und bislang zuverlässige Batterie.
