Battery Info

I have just purchased a VAMO - vivi from fastech and have a question about batteries -- what is a protected battery and are they interchangeble with non-protected? Any help would be greatly appreciated.

Protected and non-protected batts are not the same and you should (from what I have read) only use unprotected batts with the Vamo as it has built in protection. I can't say what makes the protected batts protected though. Sorry. But I'm sure some with more knowledge than I will come along and save the day!!!

there is a small circuit that senses dead shorts, over charge and under charge on a protected battery. I use protected batteries (because it was all I had) in my SID and I have no problems with them.

Here is one of the best deals for batteries to the Vamo Panasonic CGR18650CH https://www.fasttech.com/products/0...onic-cgr18650ch-rechargeable-2250mah-37v-1865

Some clarification is in order here. There are two types of Li Ion batteries - protected and unprotected. ONLY THE PROTECTED variety of Li Ion batteries should be used in APVs. These batteries use a more combustable chemistry and when stressed can overheat and explode. Thus they require a built-in protective circuit when used in APV's. These should have an "IC or ICR or NCR label" on the battery.

There is a second category of APV batteries - high drain, safer-chemistry IMR Li Mn batteries. These use a safer, less volatile chemistry that do not require protection. Instead of exploding when stressed and heated up, they merely vent hot gas. HOWEVER, this gas can be hot enough to cause severe burns or cause fire damage to property. These batteries will be labeled "IMR" on the battery. Panasonic has recently come out with a hybrid/IMR with a "CGR" on the label.

Unregulated mods (mechanical) have minimal protection. This is usually only a collapsable hot spring and vent holes to allow hot gasses to escape and hopefully slow a runaway battery down. Using a Vape Safe Mod Fuse adds a layer of safety to your mod that may prevent a runaway battery from beginning.

Regulated mods (variable voltage/power) have built-in safety features in their processors to detect atomizer and battery dysfunctions before they happen, and will shut down and refuse to fire. Since they use boost circuit technology, they require the high drain IMR batteries to acheive higher voltage.

I have just purchased a VAMO...and have a question about batteries -- what is a protected battery and are they interchangeble with non-protected?

Because the Vamo is a regulated variable power APV, it requires a high drain IMR battery, not the protected Li Ion variety.

Batteries of the new age can't be allowed to get low on volts cos the chemistry inside them has a fight and burns the house down. So they cut themselves off once they get low. Think of an ego battery - once the charge gets low it still has plenty power to brightly flash the fire button and inform you it needs charged, but it won't supply any power out. The protection you refer to is similar ie it'll stop working when volts get low. Unprotected don't have this protection so you need to notice when the power is getting low and make sure you charge it before the house fire. Vamo's, as stated above, have built in protection so they'll stop working before your battery gets too low, and therefore unprotected are fine. There's also some reports of protected batteries not working in Vamos, something to do with the two protection circuits fighting against each other I believe.

Thanks for all the information - I want to order some extra batteries and I need to know what type to get.

 

[E_DeCastro]

I'll be buying unprotected batteries after this.

IMR safe chemistry to be more accurate.

My understanding from reading here is the Vamo will not operate on a protected battery because they shut down when pushed as hard as the Vamo can push them. I have been using unprotected flat top Efest 18650 IMR batteries in mine and they work just fine.

 

[E_DeCastro]

no they wil work, I have been using them for months.

just not the best choice in batteries I suppose

Depends on the amp ranting and amp draw. In general, mods with boosters (like Vamo) recommend high-drain batteries like the IMRs.
