Powerizers and other questions

[Codrut Popescu]

I have several questions about the Powerizer batteries (I own for the moment only 2 of them ordered from Notcigs, and I am waiting for 4 more to be shipped):

- What is the maximum discharge for Powerizer Li-Ion batteries (Ampers)?

- Where are they made? China? USA?

- What kind of built-in protection do they have?

- It happens that I do own a high quality digital multimeter (Fluke 175, a true RMS multimeter -250 USD device made in USA) and I measure the voltage from time to time in order to check if they are okay. As it seems that if they will be ever exploding this will likely happen after you take them from the charger and using them the first time, if I measure them immediately after taking them off the charger is there any danger of explosion at that time?

- Can I predict their failure with a digital multimeter?

- Is there any danger in batteries being damaged during shipping? You know, the postal service is not necessarily careful with packages.

- I do charge them using a TrustFire TR-001 (also from Notcigs) on which I replaced the power cord in order to make it work in the 220 V grid which we have in Europe. The device is rated 100-240 V and it is working fine, but should I consider buying perhaps a better charger? This one is made in China...

Thanks

the only answer I know to your questions is this one...

Powerizers are NOT protected batteries, this is why they should ONLY be used in your buzz. The Buzz has several forms of protection within it's circuitry.

They would fit in my Roughstack, but it is an unprotected mod, and that would be BAD.

In the battery safety sticky buzz mentions that the Pro PV limit actual battery draw to about 2A maximum. The buck regulator functionality is handling any higher current seen by an atty. Even when you run a 1.5 ohm dc at 4.7v, 3.4 amps seen by the atty, the batteries are only seeing about a 2a load.

I think I'm beginning to understand this a bit better.....so this is a very good thing! The batteries are not taxed to maximum whatsoever, hence no overload, no worries Peachy Keno!

Yes, buzz has multiple electronic safety functions, then there's the three good sized vent holes, then there's the delrin plastic bottom cap. It would take a really conscious effort, like plugging holes, soldering end caps, bypassing the PCB, to make the unit do something bad.

I"m glad you are understanding it all FreeFire! As for me, I'm just gonna trust all you smart Buzzards to keep me safe. LOL

Notcigs PV's and batts sold by Buzzkill. <---- I'm good to go!

One thing that can't be repeated enough...altho safe to use in the BuzzPro, Powerizer batts are not protected and should never be used in any other mod

Just ordered my Buzz Pro and had the same question. I hit all the stickies, Batteryuniversity, then looked up the Powerizer rcr123a's that are coming with it and the spec sheet stated a maximum continuous discharge of 1200 ma or 1.2 a. If I use the BP with a standard 2.0 ohm carto at 3.7v, this comes to 1.85a. This is under the BP limiter but still over the discharge rate of the batteries. Is this a problem or, as is more likely, have I missed something somewhere?

The Powerizers are rated at 2.5 C so 650mah x 2.5 = 1.625 amps . we run slightly above this , BUT that is a 100% duty cycle rating , in other words FULL TIME discharge until empty , we use them in a different capacity like 15-20 % duty cycle , we have NEVER had a outgas or failure other than Stop working bad. no liquids come out or anything like that that I know of.

We will be going to a protected battery very soon to adhere to ECF guidelines.

I believe I understand. Safety wasn't my primary concern in this mater as I know the BP already has that covered for me. I just didn't want to abuse my batteries overly much and am trying to learn as much about them as possible. I killed one of my first 510 250 mah batteries with a LR carto when I fist started and that taught me a valuable lesson... Knowledge is power.

LOL LR with 250 mah 510 batt = POOF !
