2 Pack 12V 100Ah Slim Lithium LiFePO4 Battery, Xtra Mini Deep Cycle RV Battery with 100A BMS & Low-Temp Protection Smart Small Lithium Battery for Solar Systems, Off-Grid Marine RV

I bought 4 of these batteries for a total of 100ah @ 51.2v. I just ordered their, single, 51.2v battery as well. So far I've had no issues whatsoever. I've used an electric kettle(1500w for 10min) to boil water, an air fryer(1500w for 30min) to fry some wings, and the batteries delivered without a hitch. The batteries are so lightweight that moving them around from delivery to installation was really easy. They don't have Bluetooth, however, but I use victron components to monitor as much as I can. At this price, you'd be making a mistake not to buy.

Well i have not finish setting up yet. but so fare it is a great battery long lasting and multi purposed a good product of the 21 century and getting Better.THANKS AMAZON for being a connecting force and the market today.appreciate it

I bought the 36 v for my golf cart. The BMS system might be bad. The battery shows no power at all when it is less than 99%.

Great Batteries, work as they should. Very heavy so install heavy dutty support.

I have purchased a total of 4 batteries. 2 from Amazon and 2 from the dumefume web site directly. they were purchased 1 battery a month. first and last purchases were from Amazon. the 2 that came directly from dumfume had a 13.0 and 12.9 volts. they both charged to 100 percent with no problems. the 2 that came from Amazon had 12.2 and 12.4 volts. they would not charge. i hooked another fully charged lifepo4 battery in parallel to the non charging battery. i then hook a 20amp charger to the non charging battery. it then charged fine. i waited 24 hours then recharged each of them. i was surprised that it took another 10-15 minutes of 20amp to top of all 4 batteries. This process was done when each battery had arrived. note that one of the batteries from Amazon came in with a hole in the box. the battery appeared not to be dented or damaged. PRO: 1: this dumefume 150ah lifepo4 battery is priced good. 2: i like the fact that it is not a smart battery. i have no cell phone and did not want or need the blue tooth feature. 3: external seems to appear to be well built does not feel cheap. no clue on interior. 4: they are light weight for the size and amperage of the battery. CON: 1: did not like the fact that i had 50% of the batteries were not able to be charged and needed a "jump" charge from another battery to get it to work. a little concerned on the bms settings because of this. i also wondered if this was caused from used cells or not. 2: no more room in the house for another battery purchase. NOTE: i have purchased these batteries to supply additional power when attached to a power station. they work great in recharging those power stations. these batteries are being used a power storage and will be sitting on the shelf for an emergency. it will be interesting to see how they hold up over time. i would have liked to see a teardown of the 150ah. there are a few online for the other amp hour versions. CONCLUSION: i like this battery. its a new frills, non smart lifepo4 that feels good to hold. dumfume does have good deals both on Amazon and there website from time to time. If i had room in my home and/or needed another battery i would purchase it again. only minor issue is the charging of this battery and long term (calendar time) will "age" well. i am happy with the purchase.

Purchase (2) for my 24v trolling motor. Long lasting charge, very light, great value for your dollar. 10/10 would buy again.

Excellent for my kayak. Very light and runs my water snake for 5 hours easy.

There batteries came partly charged and well-packed. I bought them to replace 2 Battle Born 100 AH LiFePo batteries that were 7 years old and not putting out full power any more. The Dumfumes are working great, charging fast and effortlessly powering my microwave through a 2000 watt inverter with little voltage drop. Check out Will Prowse's tear down on YouTube where he finds them of very high quality! These batteries are an outright bargain.

Betreibe damit eine 220V Wandler für eine Gefriertruhe & wird über solar geladen. Funktioniert tadellos.

tres bien, conforme et bien emballe, je conseille

Batteria utilizzata da ormai quasi un anno in camper con inverter collegato e ricaricata da pennelli fotovoltaici,la capacità effettiva secondo il test è di circa 300ah perciò corrisponde a quella nominale della scheda. Testata anche in scarica con correnti fino a 120a e non ha dato nessun segno di cedimento. Vedremo nel tempo se rimarrà affidabile con i cicli di scarica e ricarica ma per adesso la consiglio vivamente se uno volesse passare al lifepo4 a prezzo interessante.

The built in BMS allows your solar controller to stay at peak amp charge right till battery is full Much quicker charging then lead acid or agm batteries Excellent quality battery The size of this battery is awesome This is the best addition I have ever made for solar energy Worth every penny Off grid since 1998

ACHTUNG: Dieser Akku ist nach nur einem Lade-/Entladezyklus ausgefallen. Er nimmt überhaupt keinen Ladestrom mehr an (0A) – getestet mit professioneller Victron-Ausrüstung (MultiPlus-II und Phoenix Smart Charger). Beide Ladegeräte funktionieren einwandfrei. Normale Nutzung (~500W Last) Keine Überlast Keine Fehlermeldungen Akku lädt einfach nicht mehr Der Support wurde mehrfach kontaktiert – keine Antwort. Für ein Produkt in dieser Preisklasse ist das absolut inakzeptabel. ❗ Wenn Sie ein zuverlässiges Produkt erwarten – Finger weg.
