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

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!

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.

Worked great. And carried everything on boat.

Bought 2 300Ah and both actually were only 200Ah. Bad brand

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

Product it’s great! Charged overnight. However, I accidentally turned off a setting on the app which would allow full voltage to the terminals. Seller was great to work with to educate me in record time and now all us well! Bluetooth connected well and allows you to monitor battery life. Will update further once we go boondocking on battery life.

Good value and seems to work great so far in my solar off-grid set up. I have a solar charge controller optimized for battery life, keeping this full and a 4k watt power inverter for electricity. No problems and I'm expecting it to last as long as I need it.

An Awesome product, I use 2 300ah batteries to power a mini spilt 12v 12,000 btu a/c for my van camper AWESOME
