excellent value in a compact package. I like the built in meter that shows voltage and an estimate of remaining capacity. I checked capacity from a full charge and got over 4000 watt hours.

Item was only 118ah. Not 300ah. Item was checked 3 times. All 3 said 118ah.Company was responsive and quick to answer. Item was sent back using their dime.I would try again as long as the item was 300ah. Spec's are par for the market average.

Arrived well packaged and charged to 13 volts. I read the docs and set the parameters on my solar controller. Before installing in the Sprinter I topped it off with my 10 amp Noco charger since the on-battery display showed 65% charge. About 3 hours later it read 100%.I have a 100AH battery that works just fine. This 300AH was acquired to help my run the accessories in the van longer when solar recharging isn't practical - too much tree cover, winter months, week-long excursions, etc. The biggest draw are my fridge and ice maker. I need my beer cold, okay? The fridge for cans of beer (and food) and the ice maker for the jockey box when I bring small kegs.Will leave the battery to sit overnight and see how it settles, and will run some load tests tomorrow and update my review with any out of the ordinary results.

If all Amazon sellers were this good, life would be so much better!Installed two 300AH batteries into our motorhome using Victron products to manage. Have been putting them to the test for the past 6 weeks and they're performing great. Did a full charge and heavy depletion and they delivered the advertised energy.The only think I wish they had was Bluetooth connectivity to the BMS so you could see what's going on in there. Not a must have, by any means, but would be nice.Customer service VERY responsive to questions. I love this company.Buy these! Highly recommend.

I bought one back in August and eventually bought 3 more. I've been running 4 of them in serries with a battery equalizer for over a month now on my 48V 5000W system. They are working great. Charging daily from the grid at first and from solar lately. Perfectly reliable power for a month now. I bought a 5th to use for my backup 12V inverter.

They’re good quality function rather well and the weight makes them more than desirable for applications where you’ll end up moving them around every so often. The 8 mm stud is nice because it cinches down rather well and being a Phillips head screw or a bolt Is rather nice for when you want to get the connections firm but not overly so the battery delivers rather decent performance and the capacity is larger than any other one for that price range customer service was helpful and knowledgeable and the fact that you offer free chargers should you want one is a large plus.
