Vamo battery appears to discharge instantly on use - please help!

[mrsdextrose]

Hi - I've been using a Vamo V3 with no issues for some time. I recently upgraded to a V5 and also bought a new Nitecore Intellicharger i2. I use UltraFire 18650 4000mAh batteries.

So I charge my batteries to full (three leds lit) using the new charger, plug one into the V5, press five times, voltage readout appears - next time I press any button, readout goes blank and nothing works. I put the same battery I've just fully charged back into the charger and it registers only one led - but then quickly goes back to all three.

So I repeat the process and exactly the same thing happens.

Try the same with my old V3 - and the same thing happens also, yet I know my V3 has been fine.

Charging and recharging batteries I've finally found one that gets my V3 working again, but otherwise I'm stumped. Have I bought faulty V5, or charger?

Has anyone else experienced this? I'd love to sort this out.

Thanks

You are tripping the protection circuit on the battery. The charger is resetting it.

eta: You should use an IMR battery

Your battery choice is your problem mrsdextrose. While the Vamo doesn't need the "best" batteries, it does need a "real" battery, and the Ultrafire 4000mAh isn't it.

Panasonic NCR18650B, NCR18650PF or the CGR18650CH batteries are better, and safer, and will work with your Vamo.
Sony, Samsung, Efest, AW and a few others have suitable batteries also. Don't let high mAh rating fool you! Anything over 1800 is good for daily use.

From what I've read, the Ulrtafire "4000mAh" is really 2600 mAh. The C rating is only a little bit over 1, so you can easily overtax it even in a Vamo, at anything over ~10W.

In short: This battery is not suited for vaping.

Many thanks for all the quick replies - I'll order new batteries asap.

Much appreciated!
