Charging 48V Lithium Battery With Solar

Awesome package. Solar with lithium battery. Very reliable

I have a couple of the micro lte solar units and so far they are awesome. The lithium battery combined with the solar panel makes going to change batteries a thing of the past. Great unit.

Iv had my two in the field since April 2023 They are solar no lithium battery just the cameras and they are still in the same spots to this day February 29 2024 iv only stopped by to occasionally format the SD card if set up properly definitely no issues

It works wonderfully charging the lithium battery included for my A6500.  Does exactly what it is supposed to do.  What else can you say.

This lithium battery is very reliable.

Great product , does pass through charging and has 2 solar inputs, I just ordered one extra battery.

Best portable battery. Fast charging time from wall outlet. Good mppt charging from solar. Lifepo4 batteries for a longer battery life. Extended battery. Big inverter to power most needs. EcoFlow quality. Way better than the Goalzero. Also the Bluetooth and wifi app is well designed

Having owned several brands of portable batteries for our off grid solar living, I was pleased to receive the DELTA 2 addition recently. The battery is extremely fast charging, reliable, and as advertised. Well designed and the app is a plus for monitoring. I love that it is lithiumFE battery based which will allow many cycles of charging.

Already own a Delta, which is a five star product. But after a recent storm left us without power longer and run time shorter than expected we needed more. Well the more we found was in a Delta 2 Max. After receiving it we tested it on our frig, Whirlpool 22cf side by side circa 2008. 10hrs afterward it had 50% battery remaining. Decided to go all in and connect our 2 160w solar panels in serial purchased for our Delta. Started charging once sun was up at 220w. Solar started charging when battery was at 32%, 1 hr later battery at 37%. We've been in and out of frig adding groceries so it has run nearly non-stop for 4 hrs at 150w but our Delta 2 Max is recharged up to 55%. Sun is setting and input has dropped to 190w. So staggered at the performance, longevity and portability we went all in and bought the 2 add-on batteries and another 160w solar panel. FYI haven't used app and don't care to. Plan on getting manual switch over for whole home backup.

Backup charging for when I need it. This availability of the solar charging system was the answer to one of my main concerns regarding using the battery backup during a power outage.
