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!

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.

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!

I'm very impressed so far. The capacity (according to their own app) is dead on, cells are staying balanced. Size was accurate. I've only been using for a few weeks so I can't comment on life but seems to be holding up very well. I'm most impressed with the app. It not only shows voltage and soc but also gives a live throughput which is great for knowing what you use and create with solar. Also creates a histogram if you leave the app running. I wish I could turn the Bluetooth off. I wish the app was a little prettier and user friendly. I turned off balancing in the app and can't get it back on (don't do that!) However, at this price so far this seems like an amazing deal!

I installed 3 of these in our 5th wheel, they work well.

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.

Complete order finally received. Customer service seemed to struggle but everything was made right in the end.

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!
