A quick follow up to my previous post, just returned from 3 weeks on the boat, anchored out every night except for 4 nights! My 300ah Lithium Ion battery worked great, now I can keep the drinks fridge, galley fridge and galley freezer all running 24/7 just like home with lots of power to keep them cool, I can highly recommend this battery for anyone that likes to anchor out for any length of time..

Purchased this to use as house battery on my boat, I'm really pleased with performance, just wish I had this long ago. I run 2 fridges and small freezer, all work even better than full power from previous pair of batteries as these charge to a little higher voltage. We anchor out lots and so happy to have something that really works well..if you like to anchor out on the hook for any length of time don't hesitate to spend the extra ,you'll be so glad you did..

Had previously bought six 100amp Lithium Ion batteries, from SmartBattery, for use in my Solar/Wind powered RV. The six batteries have been in use for over one year running 24/7. I wanted an additional battery bank so I bought this 300amp battery. I am completely satisfied with my purchase. So much power in such a light battery and it looks great too. Will be buying a second 300amp battery for a grand total of 1,200amps!
