Hi there, i just bought Efest purple battery, 2500mah, 35A, 3.7v, fully charged using at my Ipv4s with dual coil rda.. but i cant vape at 100watt, it shows 'check battery', kindly assist please....

Odds are that your coil resistance is so low the mod can't deliver that set power at all. Try building a higher ohm coil.

Also - Just in case you weren't aware - those Efest batteries are 20 Amp CDR (Continuous Discharge Rate), which is what you want to be paying attention to when looking at batteries. The 35 Amp rating is the Pulse rating (and may likely be overstated).

Hope it helps and Happy Vaping!

I don't know the mod well - but I'd be surprised if "check battery" was the message for too low a build - I'd expect "lo ohms" or something.

But doesn't the ipv4s take two batteries?
Are they in the right way?? (I think it goes 1 down, 1 up?)

Yup. It takes two (2) 18650 batteries, max at 120w, fire as low as 0.1
