48V 100AH Lithium LiFePO4 Battery,Wifi/Bluetooth, Auto Fire Suppression,Built-in 100A BMS, 5120Wh Server Rack Battery with 3U Rack Mount Kit. for Solar Energy Storage, Home Backup Power

Great battery! I really like how long it last between charges, and the Bluetooth functions. Great alternative to AGM batteries . But it is super small for as much battery power it provides

Very reliable so far. Runs great. Like the blutooth app so I can monitor it.

200AH Mini PUPVWMHB Bluetooth Battery. Arrived earlier than estimated, packed well. Came at 50% state of charge. After removing my existing RV battery box it dropped right into the opening in my truck camper, no cutting. Sweet! It replaced a 81AH lead acid, figure only half of that is usable = 40AH. This 200AH lithium which is fully usable has 3x more capacity at 42# vs 50# for a single 81AH lead acid. Things to know- Not a product issue, but I feel the recommended BMS app seems lacking, but other apps will work. Do a web search for JBD BMS. Also, it's Bluetooth has no switch and is always on which might be a security issue. 3 other batteries I have purchased (a different brand) all have a switch for Bluetooth. I'm concerned someone with a app and bad intentions could walk thru a campground and mess with the battery settings. All in all I'd say it's a nice battery for the price. 2 requests for the manufacturer- Add a switch to turn Bluetooth off, and pronounce PUPVWMHB for me!

Battery came packaged very nicely and works as it should. The battery fit in the existing battery box that replaced a 100aH AGM battery. So I now have 200AH in the same footprint of my 100aH original battery.

Very good value for money. The BMS works well, I inadvertently tested the short circuit protection. The battery went into self protect mode, then reset itself after 10 minutes - nice. The Bluetooth app is not available through Google play, which meant I had to bypass some security settings and also deal with some Chinese tick boxes.

Awesome well built battery. Long lasting time and super lightweight. The self heating feature is key for those colder climates. I have mine rigged up to power my fishfinders on my boat.

i have been testing this battery for a while now. it is as described and im impressed. great value and light weight. i will be posting a full review and video on YouTube of this battery and others similar. Hoping to do more business with this company and maybe more reviews.

Long lasting but it does take a while to recharge. I tried 5 amp trickle charge but went to a 10 amp to get the job done. Use it for my Minkota trolling motor and it works great.

Working as expected, great value for the price!

So far so good

Review of the 12V 330Ah PUPVWHMB LiFePO4 Battery An In-Depth Assessment for UK and Irish Users Let’s get the dry blurb out of the way. Overview The 12V 330Ah PUPVWHMB LiFePO4 battery is a high-capacity lithium iron phosphate solution aimed at users seeking reliable, long-lasting energy storage. It is well-suited for a range of applications, including off-grid solar systems, motorhomes, marine setups, and backup power systems. This review covers the battery’s main features, performance, advantages, and potential drawbacks, with a focus on its suitability for British and Irish consumers. Main Features • Capacity: 330Ah at 12V with a 200Ah JBD BMS delivers a substantial 4,224Wh of energy, sufficient for long-term and high-demand use. • Chemistry: Utilises LiFePO4 (Lithium Iron Phosphate), renowned for safety, stability, and long lifespan. • Cycle Life: Typically rated for 3,000–5,000 cycles at 80% depth of discharge, meaning years of regular use with minimal degradation. • BMS (Battery Management System): Integrated BMS protects against overcharging, deep discharge, overheating, and short circuits. • Weight & Size: Considerably lighter than comparable lead-acid batteries—this makes it easier to transport and install. • Maintenance: Virtually maintenance-free compared to traditional lead-acid batteries. Performance Users report consistently stable voltage output, even under heavy loads. The battery’s ability to deliver its rated capacity is backed by its advanced BMS, which actively monitors cell health and balances charging. In practical terms, this means fewer worries about sudden power drops or system shutdowns. Charging times are also notably faster than with lead-acid alternatives, particularly when using an appropriate lithium battery charger. The LiFePO4 chemistry also performs well in colder climates, which is a significant advantage for users in the British Isles, although extremely low temperatures can still impact overall performance. Advantages • Longevity: With a lifespan of several thousand cycles, the PUPVWHMB battery offers excellent value over time. • Safety: LiFePO4 is inherently safer than other lithium chemistries, with a lower risk of thermal runaway or fire. • Lightweight: Easier to handle and install than lead-based counterparts. • Consistent Performance: Reliable power output, even under sustained loads. • Low Self-Discharge: Can hold a charge for months with minimal loss, ideal for backup or seasonal usage. Potential Drawbacks • Initial Cost: The upfront investment is higher than lead-acid batteries, though this is offset by longer service life and lower maintenance. • Charger Compatibility: Requires a compatible lithium charger for optimal performance and longevity. • Temperature Sensitivity: Although better than many lithium types, charging below 0°C is not recommended, and extreme cold may reduce capacity. Applications • Off-grid solar and wind energy storage • Motorhomes, campervans, and caravans • Marine and boating applications • Uninterruptible power supplies (UPS) and home backup systems • Golf carts and other electric vehicles My Takeaway as an Everyday Bloke The 12V 330Ah PUPVWHMB LiFePO4 battery offers a compelling package with outstanding capacity, safety, and long service life. While the higher initial outlay may give some pause, the reduced running costs and hassle-free ownership make it a sound investment for those needing dependable power storage in the UK or Ireland. Its robust features and reliable performance make it suitable for a wide range of demanding applications, and it stands out as a modern alternative to traditional lead-acid batteries. I'm very satisfied with this battery. I’m going to have four of these in series for nearly 17KWh of battery storage, with a nice hybrid inverter, 17KWh of power for £1200? That’s a bargain all day long. I never overload my batteries, and I’m not going to for the sake of a review, I need my gear to last it’s proper lifetime. But I will say that this battery wil pull it’s rated 2.5KW all day long, but I won’t ever need to pull more than perhaps 1.5KW of power per battery with four in series. Build quality is the same as other plastic boxes, fit and finish is good, and now I have found what I think personally is a great battery, I don’t need to look elsewhere. The Bluetooth works well and has been reliable with no issues. I use the advanced JBD app on my phone. The app that is tailored to these batteries doesn’t allow for the granularity I need going forwards. Even though I live and was born in the UK, I lived for many years in the United States, which is where I went to school for solar. I have been waiting since the 6V golf cart Trojan lead acid battery days for affordable power storage. What more could a person want. Now I’m back home in the UK, roll on the sunny week of summer, 😂

Excellent battery , great price Quick deliver , app is good too…

Fijne robuuste accu. Kan echt wel een stootje hebben, al verschillende keren ont en opgeladen, weet van geen ophouden, echt een aanrader !!
