Efest IMR Chemically Safe batteries , are they safe ?

[look30]

So I bought these batteries to be used in sigelei Zmax V3 telescope and I am unsure if they're safe or not as they don't have a protection circuit :

Efest IMR 18650 2250mAh 3.7V Rechargeable LiMn High Drain battery- button top-Efest battery for E-cigs

I got both the 18650 and 18350 .

Does the Zmax has a Protected Circuit built in ?

You're good.
The protection is built into your Zmax.

Yes, V-V / V-W boost circuit processors have built-in protection to sense a potential short from a battery and shut themselves down.

The IMR, high drain batteries do not use a protection circuit because they use safer chemistry materials that are not as volatile as Lithium Ion batteries. I consider their use to be safer than protected batteries even in mechanical mods that do not have built in protection.

Efests have a reputation as being a good battery. Also AW and Panasonic are excellent brands. Hopefully you have a high quality charger to go with those batteries; ie Pila, Xtar, or Nitecore.

I am using E-fest batteries with my Sigelei Zmax V3 Telescopic flat top. I'm using single cell 18650, 18500 and 18350. I won't be using 2x18350. Not going there. I like the single cell safety factor. The Zmax has a 4 amp limit so I'm very confident in using the E-fests.
