  • Holds its charge nicely
Style: 12V300AH
I didn’t get into my camper until late in the season. The battery held constant from when I got it until it was installed. After its first charge cycle, I turned off my converter so that all twelve volt power was derived from the battery and not the 120 volt. I had some extra steps in getting my camper de winterized, so I ran the lights quite a bit, ran the slide in and out at home and on the camp site. Used the jack up and down at home and leveled the camper, camped all weekend and the battery was still at 72%. I was pleasantly surprised. ... show more

  • Great litium battery
Style: 12V300AH
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. ... show more

  • Off grid shed setup, very pleased!
Style: 12V300AH
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! ... show more

  • Reliable power
Style: 12V300AH
I bought these as an upgrade to power the equipment on my mobile dog grooming vans. I use 6 per van for 1800 Ah total. Gives me all the power I need to run my high use devices (including a/c and high velocity dryers) all day with power to spare. Being able to monitor usage via app is really helpful as well. I’m using this system in multiple vans now and so far no issues. ... show more

  • Great product! Fabulous customer service!
Style: 12V300AH
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. ... show more

  • Should of bought this 1st
Style: 12V300AH
So battery came to me super quick, This battery seems to be really nice at a reasonable cost . I've been using multi 100ah batteries and this single 300ah is the exact power out put but costs less. Buying three 100ah batteries @$300 each for $900 or Buy this one. Easy decisions don't you think? And now I have the others as back ups too! ... show more
