Epoch 12V 105Ah Heated Bluetooth (Essential): 12 V specs and what it works with
The Epoch 12V 105Ah Heated Bluetooth (Essential) accepts up to 100 A of charge current and its BMS is rated for 105 A continuous maker spec. Of the 12 RV converters we list, 3 pass both the lithium-mode and current checks for one battery calculated. Data updated .
RV converters and chargers
Each converter is checked against one battery: does the maker list a lithium mode whose voltage sits inside this battery's published charge range, and is its output within the battery's max charge current? For two or more batteries in parallel the current limit adds up; use the planner.

DC-DC chargers (alternator charging)
For alternator charging, use a DC-DC charger and follow its maker's instructions. The check below compares each charger's rated output with this battery's max charge current.
| Model | Charge current |
|---|---|
| REDARC BCDC1240D Dual Input 40A | WorksThe DC-DC charger's rated output is within the bank's published max charge current. |
| Renogy 12V 40A DC-DC Battery Charger (RBC40D1U-G2) | WorksThe DC-DC charger's rated output is within the bank's published max charge current. |
| Victron Energy Orion XS 12/12-50A | WorksThe DC-DC charger's rated output is within the bank's published max charge current. |
Inverters
Full-load inverter draw is continuous watts ÷ the inverter's published peak efficiency ÷ 12 V, compared with this battery's BMS continuous rating calculated.
| Model | Continuous draw | Surge draw |
|---|---|---|
| Magnum Energy MS2012 Pure Sine Inverter/Charger | NoAt full rated power the inverter would draw more current than the bank's BMS is rated for continuously. | Works, tightThe inverter's rated surge draw is above the bank's published BMS peak current; large motor starts may trip the BMS. |
| Victron Energy MultiPlus-II 12/3000/120-50 | NoAt full rated power the inverter would draw more current than the bank's BMS is rated for continuously. | Works, tightThe inverter's rated surge draw is above the bank's published BMS peak current; large motor starts may trip the BMS. |
| Victron Energy Phoenix Inverter 12/1200 VE.Direct 120V | NoAt full rated power the inverter would draw more current than the bank's BMS is rated for continuously. | WorksThe inverter's rated surge draw is within the bank's published BMS peak current. |
| Xantrex Freedom XC PRO 3000 | NoAt full rated power the inverter would draw more current than the bank's BMS is rated for continuously. | Works, tightThe inverter's rated surge draw is above the bank's published BMS peak current; large motor starts may trip the BMS. |
Cold-weather charging
Minimum charging temperature: -20 °C maker spec. Built-in heater: yes. See how the low-temperature check works.
Box fit (BCI group 24)
The maker labels it group 24. Against BCI's maximum group 24 dimensions: NoAt least one battery dimension is larger than the box dimension. Battery box fit guide
Bank energy for one battery: 1,344 Wh at 12.8 V nominal calculated.

Notes on the sources
Epoch states the battery's heater runs on incoming charge current (charging resumes at 5 °C), and recommends a charger temperature limit of 0 °C unless the charger has approved cold-charge logic.
In the maker's words
“Charger Temperature Limit Setting: 0°C (32°F) / 55°C (131°F), unless the charger has approved cold-charge logic” (low temp cutoff quote; source)
