I don't say this often, but HELLLLPP~~!!

Okay I need anyone's input on this. If you don't know how electronics work, you won't help me. I'm not posting this in modders, cuz well it's not about mods. I need some general HELP!

I bought 2 PIF Riva's, yaaay. I decided frack it and tore one apart. Super easy to do BTW!! Anywho looking for someone to tell me what could possibly be wrong with these suckers. i assume something is wrong with the circuit board that's not allowing it to charge or vape. So here's a quick video I made any pointers that can help me figure out their issue would be greatly appreciated.

No, I do not have multimeter or anything like that, but i know the batteries work. i personally think it's in that little board... tell me what you think!

Have you tried charging them with a USB charger so you can see what the charger lights are doing ?

The Riva flashes like that and stops when the battery has a little bit of power left, not when it's totally dead, it shuts it down. I would say it's the board personally, but the board might snap out of it and decide to work if it likes a certain charger, i've had this happen with some other e-cig batteries. That's why im curious if you've tried charging them with a couple different types of chargers.

yes i've tried a homemade passthru, usb, and pcc. it's not a huge big deal i bought them PIF to tinker with, just wanting to know if ppl thot it was something other than the lil board.

i'm gonna try wiring it with a different button and totally bypassing the board

I believe the board is the Mosfet controls. That is the part that typically fails when attys start failing and the resistance drops below 1 Ohm. If you can bypass the board somehow the battery should still work fine. have no idea how to go about that though.

what if i just said eff the board and used a switch of my own? think it would fry the battery?

i would of course add an led with a 1/8 watt resistor on it. think it would work if i just incorporated it into my magnum style mod?

 

[Shan B]

or what if i tried putting the battery in my mod and charging it, think that would work?

i'm not trying to blow a battery up in my face, is all.

You're trying real hard... you could blow it up....be careful

Shan, I admire your curiosity and spunk with this project, but I think you may be better off junking the battery and board and switch, replacing the power supply with a USB cable using a 3 amp button. I suggest that you check the mods section on how to make your own 5 V USB direct PT. You need a 2.0 amp power supply to go with it.

If you really want to repair the eGo with that battery and button , you really NEED a working board. The button is not rated to handle the current, it needs a MOSFET (power circuit) for the button and that circuit is part of the charging as well.

OTOH, I suppose you could try 14500 batteries to see if they fit in there with a 3.0 amp button. Then you could charge the 14500's externally using a separate charger, but IDK how you open and close the eGo to change the battery. I suppose you could rig a AA to 510 connector converter for the charger.

The center of the atty connector is usually the positive connection, the shell is the ground. And use a protected 14500. If it won't fit, go with the USB direct PT.

BTW I have no idea if the 14500's would even fit. The idea is to use the eGo shell as a box mod (tube mod) replacing the button and battery.

Hope this helps.

P.S. I consider the disclaimers in the mod section to be in full effect......that is really DIY and at your own risk.

Regarding the video.... Lithium Ion batteries are "cut off" by the control circuits when it gets to "low charge"... NOT DEPLETED. So, for example, a new battery would charge to 4.2 volts, run fairly consistently near 3.6 volts, and be considered "done" at 2.75 volts. The is all part of the board/protection circuit. So the eGo may be considering the battery "done", but it is not dead. Thus, it will power your LED and the carto for a little bit. If you run a Lithium Ion battery to zero, it is ruined (supposedly).

Pops,

TY for all of your input. I've read alot of your posts and replies and I take everything you say to be 99.9% truthful in situations such as mine. (No one is always right, and is why I say 99.9)

I was a total idiot girl and did some things before you got a chance to reply, and indeed you were right. LOL I blew it. LOL. You live and you learn, just glad all that stuff came out of the top and didn't blow sending shrapnel of all sorts at me. So I'm going to just use your advice and go with junking the batteries and board. I'll use the lil rubber from the button, the shell casing and the 510 battery connector but eff all the rest. Now I know what they mean by batteries "screaming", indeed they do.

So anyone playing around with UNPROTECTED batteries. Heed my warning, they can jack your day up. Pay the extra money and get some protected batts if you're going to try to mod an eGo, Riva, Tornado, TRex, etc.. they come with UP batts and I wouldn't suggest ANYONE (no matter how inclined you are) to mess around modding with these things. PROTECTED is the ONLY way to go. If you can't afford to keep buying things, like me, wait until you can. It doesn't pay to take shortcuts when it comes to electronics and circuitry.

TY again AP! I'm just going to use the safe parts to make another mod. Worth a shot, but not worth the burns or scars.

I've been wanting to make my own PT, but was so wrapped up in modding my own PV that I forgot about it. So... PT making is on my agenda today. I keep random electronic parts, like a guy, you wouldn't believe the stuff I found packed away in my closet. Computer mother boards, hard drives, torn apart dvd players, random plugs, chords, and best of all 4 different power supplies!.... I even had 15" speakers in there and a JL Audio Sub... who woulda thunk?

In the mix I have 2 that are rated OUTPUT: +5.0V==2 A <<<thinking this is what I need

Gonna check into PTs to see if I need any resistors or anything other than the PS, switch, and Connector.

Thanks AttyPops! You rock!!!

PS
No a 14500 won't fit in there. they are about 6mm too long and about 3mm too wide
