REDODO 12V 100A Battery
With Low Temperature Protection

We see a number of blogs and video where lithium batteries are used in RV installations and usually these are associated with a large and very expensive solar build out. While these types of installations are worthwhile for those who’s RV travel takes them off grid, there many who own RVs who want the benefit of using lithium batteries who are wanting to replace their heavy, limited capacity Group 27 style lead acid batteries. We wanted to find a lithium replacement for lead acid batteries that were feature rich, at a reasonable cost, and could be used for campers, van builders and small bus builders. We have reviewed a number of larger 200Ah and 300Ah lithium batteries and wanted to give an option for those needing a 100Ah lithium battery that cost less, but maintained all the advanced features found in the more expensive, larger batteries. We evaluated the REDODO 12V 100Ah Lithium Battery with Low Temp Protection and found it not only performed very well, but meet all the features were were looking for in an affordable 12V lithium battery, and cost less or equal to most popular AGM lead acid batteries.

REDODO 12V 100Ah Lithium Battery

The REDODO 12V 100Ah Lithium Battery tested offers a number of benefits when compared to traditional 12V 100Ah AGM batteries having a discharge rate of only 50% and weighing 60lbs or more.

The REDODO 12V battery tested is equipped with a battery management system (BMS) that will automatically cut off of charging when the battery temperature is lower than 32°F (0℃), and automatically resume charging when the temperature is higher than 41°F (5℃). This is critical for all lithium batteries preventing damage to the battery during freezing temperatures.

REDODO 12V 100ah Lithium Battery is made of high-quality Grade A prismatic cells which we prefer over other types of lithium battery construction. This battery supports 4000+ deep cycle charges at 100% and has a 10-year service life which is superior to most AGM batteries having only 2-3 years and 200-500 cycles.

Evaluating the REDODO 12V 100Ah Lithium Battery

As with all of our lithium battery evaluations, we place the batteries in an environment that demonstrates daily use in an RV where no campground power is available. It the video below, we show how long the battery will sustain a number of 12V DC and 110V AC appliances until the battery is depleted. The test was done with no external charging using the battery only for power. We found the battery performed very well with one 10 hour test period that included the charging of two tablets, and using a 1000 Watt pure sine wave inverter powering a number 110V AC devices including a LED light, small campus style refrigerator that had not been pre-chilled, an oscillating floor fan, 19 inch TV, and a Roku streaming device. After the test, we left the refrigerator running for another 12 hours to deplete the battery. We also tested the battery using a 3000 Watt inverter to see how the battery performed when the max continuous discharge current exceeded 100 Amps.

Results

Overall, the REDODO 12V 100Ah Lithium Battery performed very well. The battery is a very good solution for those who are wanting to replace their 12V lead acid battery with the benefits of greater power and less weight in a Group 27 form factor. And the REDODO 12V Lithium Battery offers a path for the budget conscious who are wanting to add lithium now, with plans to add additional additional batteries in the future.

Our thanks to REDODO for providing the battery for our evaluation. We have provided helpful links below if you are interested in knowing more about this and other REDODO battery products.
