help me understand batteries

[donaldbyrd]

I have a sigelei zmax v5 and would like to get another 18650 battery for it. Their web site says you should not use a protected battery in it. Can some one explain to me why that would be? Thanks in advance for any help

Possibly size fitment issues?, a conflict with the electronics for some reason?...who knows....I would contact the manufacturer for at least direct from the source information regarding this.

I am assuming that the ZMAX has battery protection already and possibly have a two in one will mess up the device

can't be size the zmax v5 is a telescope. I have a bit of understanding when it comes to electronics and can not fathom how "double" protection would interfere with the electronics of the device.

The ZMax is a regulated mod. It uses boost circuit technology to create higher voltage. A protected NCR battery does not have the capability for high drain applications like an IMR battery does.

A basic rundown of replaceable, rechargeable batteries used in mods:

NCR Li Ion Lithium ion class batteries, also called "protected batteries".

• These are batteries that have a built-in protective circuit. This is because they contain a volatile chemistry that can become unstable when hot, and when short circuited can vent with flame in an event that is called "thermal runaway". If safe battery practices and common sense is used, they are considered relatively safe.

• These batteries have a higher capacity (mAh rating) than IMR batteries, and are primarily used in single voltage applications where long battery time is the primary objective.

IMR Li Mn. Lithium manganese class batteries. Also called "high drain", "safer chemistry", and "unprotected" batteries.

• Use a safer and more stable chemistry and therefore do not require built-in protective circuits in the battery. These generally are used in regulated mods that use boost circuits to achieve variable voltage-wattage, but they can also be used in single voltage mechanical mods, especially when using sub ohm vaping.

• This class will have less capacity in mAh rating compared to protected batteries, but are superior to them when maximum load current is required, such as in regulated mods or mechanical mods using sub ohm.

thanks Baditude that helps

so the 18650 3.7V Panasonic Hybrid IMR CGR18650CH should be a good choice, if I can find them they seem to be sold out every where.

Also, with a device that has the "protection circuit" built in...the battery protection circuit could do what my VAMO V3 did, limit the overall current..when I would hit the button on anything higher than 4.0 watts...DOINK system would shut down...had to unscrew it and put it back in to turn the system back on

Also the "protection circuit" prevents you from draining the battery TOO low (Li Ion cannot go below 3.2vdc per cell (actually the I KILLED IT voltage is around 2.7 to 3.0vdc depending on the chemistry of the battery)

A device housed protection circuit will prevent you from pulling the battery too deep, on a mechanical mod..there isn't anything there to keep you from hitting it and hitting it and hitting it till you effectively murder the battery

Welcome to RTD Vapor has alot of good batteries that work quite well in these APV's and are fair priced too

RTD Vapor has them:

Hi, I also have the Sigelei V5 and have been trying to figure out the same thing. I am so glad you posted your question about which type of battery to buy. Every since I have been reading all the dangers of using unprotected batteries I started have second thoughts about this mod, which I just love. Thank you to all the other posters for all the information, it is very helpful.
