Checks
The compatibility checks behind every verdict
Every verdict on this site comes from 4 written-down checks that compare one maker's published number with another's calculated. When a maker publishes no number, the verdict is “not published”, never a guess. Data updated .
- Will my RV converter charge a lithium battery?Does the converter list a lithium mode, and is its charge voltage inside the battery maker's range?
- Alternator charging through a DC-DC chargerIs the DC-DC charger's rated output within the battery's max charge current?
- Charging lithium in the coldIs the coldest temperature above the battery maker's minimum charging temperature, or does it have a heater?
- Can the battery's BMS feed my inverter?Is the inverter's full-load DC current within the battery's BMS continuous rating?
The house assumptions these checks use (margins, charge voltage, efficiency defaults) are listed with their labels on the methodology page.
