Match the thread, then the voltage
510 is the screw fitting, not a promise that every cart you already own will fit the crown or the voltage range. The Core listing mentions a wide crown for a range of atomiser sizes. The Veil Bar Flow listing names 510-thread atomisers and refillable tanks up to 2 g or 14 mm. Read the limit on the model you buy.
Other listed batteries, without their figures repeated here, are the Vessel Compass, the Vessel Expedition Trail Edition, the Cartisan Veil Bar Pro Evo, the Veil Bar Duo, Cartisan The Inspector and the G Pen Hydout. Open the listing before you compare them with the Core or the Flow.
