Charging batteries question

[scoopbb]

Hi guys, i just purchased a Vtube mini kit and it comes with the charger and a battery. i also picked up a DMM to check the voltage after it charges.

I'm currently debating getting an xtar wpII, 2 18350 AW IMR batteries and a safe charging bag but its 50 bucks and i wanted to wait a little bit before dropping more money.


do you guys not recommend charging the batteries with a safe charging bag or will i be alright using the charger that came with the vtube and that battery for now as long as i watch it and use the DMM? prefer not to have my face blown off or better yet my house.

Generally speaking, the best bet is to use the charger that came with it, it supposed to be best tuned to the output that the battery is supposed to receive. I'm actually interested to know if anyone has had such a catastrophic battery episode. i haven't come across any horror stories so far and I get the feeling that modern batteries are actually pretty safe.

I put my sealed battery assy. in a can when I charge them. I am however going to get one of those bags. $50 sounds a bit high. Try Amazon. I plan on getting one there.
FYI if your testing just a battery not a sealed assembly the DMM will do fine. But it you test it in the tube you will not get a good reading. The Voltage coming out of most if not all mods is a Pulsed tight square wave not a true DC voltage. If you want to test it in the tube or an assembly you will need a true RMS meter. May not be a big deal though it will give you and idea. Also you need to test them when you get them to have as a reference. Then you will know after that fist full charge what to expect.
Hope this helps.

They also make a little board that attaches to the tip of the battery in ones that have removable batteries. It has a current limit if there is a problem that board will die but cut of current flow.

oh the DMM was just to test the batteries after charge to make sure its not overcharging.

also 50 bucks was for all those things, including the bag. the bag alone is like 7 to 9 bucks but its 6.50 to ship.

what kind of can are you putting it in?

Great where at.

The can was an old salmon can It has is tapered coated and steel. No zinc coating. Some sort of plastic. But that is for my sealed batteries. For now i trust the battery only charger. I've been charging batteries a long time and the worst I've ever had happen is for the battery to leak.

You can get the bags a lot cheaper if you shop around:

$1.99 Lithium Polymer Charge Pack 18x22cm Sack

$2.73 Lithium Polymer Charge Pack 25x33cm JUMBO Sack

But you could put it in a coffee can on it's side. Some folks charge them in the sink. I don't because of the worry about fogetting and turning on the water. LOL

I agree, you can screw up a unit with the wrong battery.

good info here. thanks

steve, it was rtd vapor

the other question i had, if i have them in the bag, when do i know its done charging, just periodically check? doesn't that defeat the purpose.

Well, you pretty much know your batteries and what to expect for an average charge time. So set a timer and check at the appointed hour. Beyond that I personally think there is too much hysteria going on about isolated battery boo boos. These chargers do not keep supplying run-on charging current guaranteed to explode the batteries if you don't remove them within two minutes of a completed charge cycle. If the chargers were designed like that we would have batteries exploding everywhere. The chargers do monitor battery voltage and do shut down charging current when the proper battery voltage is attained. This is what they are designed to do. A defective battery or charger can be a problem. But that should be a rare exception, not an expected norm.

i didnt even think twice about using these types of batteries before. but once i began looking up the joytech mod, and saw people bringing up exploding batteries left and right, it put that fear in me lol.

this isn't really an expected thing for me, just now a conscious paranoia.

I'm using the setup xtar wpII, 2 18350 AW IMR batteries for my vmax. I got three different sets of batteries,(my ocd i guess). I've never had any problems. You need a pair of extra spacers for the 18350's to fit the charger. I never have used a bag or container for charging mainly because I never leave them alone. I also did a lot of tech work back in those days. Just pay attention and keep a eye on them. Don't let em get hot or leave them hooked up overnight. The charger that came with my "kit" only charges one battery at a time and I think that stinks. IMHO.

I' ve seen those reports also. I'll say it again along with others I hope. "NEVER LEAVE YOUR BATTERIES UNATTENDED. DO NOT GO TO BED OR OUT FOR THE EVENING WITH THEM IN THE CHARGER. Watch em like you left the oven on and no worries.

RTD vapor has the the xtar wp2 II for $20, aw imr 18350 for $7.60 ea. shop around. i heard good things about the charger. its a smart charger. look into it.
