Epoch RV Battery 12V 300Ah 1080 – Heated & Bluetooth & Victron Communications

We evaluated the Epoch RV Battery 12V 300Ah with Bluetooth, self-heating, and Victron communications as our primary off-road power source. This the perfect 12 DC power solution for those who have large RVs with residential appliances and the need to operate when no campground power is available. The Epoch RV Battery 12V 300Ah is a strong contender for those who camp off-grid and need the extra amperage to extend these stays for those days when solar production is a challenge.

Epoch RV Battery 12V 300Ah Evaluation

We put the Epoch RV Battery 12V 300Ah to the test using our Montana 5th wheel as a real-world environment powering a large GE residential refrigerator, lights, TV, and slides over an extended period of time without any means to charge the battery. Our efforts were to simulate a long tow lasting 10 hours, an over night stay, and then continuing to the next destination for another 7 hours. We relied on the Epoch RV Battery 12V 300Ah only, with no provisions for solar, campground, or the 7-pin connection to our truck for charging power.

Over the evaluation period, we used both the iOS Epoch LI-Ion Bluetooth app for iPhones and our Victron Smart Shunt monitor the performance of the battery. As a check and balance between both monitoring platforms, we found the reporting to be within a percentage point of remaining capacity and available voltage.

Epoch RV Battery 12V 300Ah Results

With the battery at full charge, the evaluation for the Epoch RV Battery 12V 300Ah exceeded our expectations. We ran our test over 31 hours and at the end of two days, we still had 26 percent, one quarter of the battery capacity remaining.

Recharging the battery with our Progressive Dynamics 75 amp charger took around 3 hours. The shortest time when have experience with any of the batteries we’ve tested to date.

With the batteries heavy duty construction, metal case, low temperature disconnect, internal heating, 11 year warranty, and much more, this is a perfect solution for our 12V power needs.
