Extra top-up battery storage

This is an amazing use of a battery. I charge it with the Temgot 20a battery charger that gets it's power from the overflow of solar energy coming into my solar battery. Then I can charge up any of my other solar batteries when they are low from the Temgot battery. Perfect for a cloudy day when I cannot store sunshine. I love the monitor on the Temgot battery. Love the battery charger too.

100 ah for trolling motor

Did extensive research and found these to be by far best bang for your buck. No other batteries compare for the price and warranty. I plan on using them for garmin trolling motor. Excited to have 300 amps available now. Would definitely recommend these batteries. My dad also bought these for his boat

Peace of mind.

Purchased for a addition to my BLUETTI Solar Generator AC180 for a guaranteed quick charge during extended outages due to hurricanes.

Appears to be a very high quality product for the price. I look forward to using it to power my Garmin Livescope system on my bass boat. Time will tell, but I would highly recommend this battery to others at this time.

Good battery so far...

I charged up the battery when I received to full capacity using a smart charge device at 14.6v. On the screen and phone application, I like the fact that the capacity of each of the four cells in the battery is shown. Probably won't be able to test in a colder environment, so I won't be able to speak to it's colder temp performance. Having Bluetooth capability is kind of neat, but I'm not sure why I have to get permission to use the phone app. I'm going to wait a full month to see how far the battery discharges just sitting (I'll check the phone app at 30 days) before considering a recharge. The BMS apparatus appears to track the number of times that the battery is cycled. I'm hoping that it will maintain most of its current so I won't have to recharge until 2-3 months. I am using the battery primarily for a ham radio backup, and other possible uses if I find that a 12v battery is needed in my other projects. So far I'm happy with the purchase. At the 1 month check, I switch my radio equipment from AC to DC load tests to see how long it will power my equipment.
