We absolutely love these Lithium batteries from TimeUSB. We use them to run 12 volt accessories mainly the 2 refrigerators we take on camping trips and Jeep rides. I tested the first Lithium battery from TimeUSB and was amazed!! It ran the 56 qt refrigerator for 4 days, that's keeping food and beer cold at a setting of 34 degrees so we bought another one to run the 2nd cooler. Very impressed with the batteries. My Bluetti (EB55) doesn't even come close to powering the coolers, 2 days tops maybe before having to recharge it. Thanks Time USB for having such a great battery.

I have had eight of the 12-volt 100-amp Pro batteries connected to create two 48-volt batteries which is then paralleled with another 48-volt wall mount battery. Been running great for several months now and, when checking the individual 12-volt batteries their voltages are spot on with each other. I have no complaints about these batteries at all and an excellent bargain for price paid. Shipping was quick too.

These two along with the four I already had gives me enough power. Good Batteries ! My diy system works great.

I had bought 2 - 12.8V 100Ah Pro batteries for my 24 volt trolling motor . They have been working great. So decided to add a 12.8V 50Ah battery for my fish finder and down riggers. Batteries are all working great and have more than enough power for my application. Very satisfied with the delivery process and customer service. I am recommending Time USB to my fishing companions. Thx Rob

Works Great for running my shop and as emergency power backup for house!

quality batteries and great support with installation and general help with sizing solar panels to batteries. could not ask for more helpful people

Put this in a battery box, added a 500w pure sine wave inverter, usb and 12v power port. This makes a great portable power station for half the money. We have used even on the garage door opener when power was out. Ran a tv and lamp over four hours one night. Not powerful and yet still hand plenty for our needs. Fine job fine job Timeusb
