Compare nominal watt-hours at the stated nominal voltage, then choose your operating reserve. Neither number alone establishes runtime at AC appliances. Inverter losses, other loads and the time between dependable charges still matter.
Check cold charging before choosing heating
Read the exact operating conditions for the heater and charging protection. A heated battery still has temperature and power-source requirements. Compare those instructions with where the battery will be mounted and the climate in which you will charge it.
Include monitoring and future expansion
The Eco listing calls for external monitoring when Bluetooth information is needed. The two exact profiles also have different parallel limits. Compare the complete installation and any planned expansion rather than buying on nominal Ah alone.
Before placing the order
Save the exact model number, check the current specification and installation instructions, and confirm the selected supplier configuration. Include any mounting, monitoring, cabling or accessories required for your build when comparing the complete cost.
