Morning Scott - Could you answer a question for me. The AW IMR batteries we get for our Reo's from RTD are they protected? Guess I am still confused why/why not to use protected ones?

I think it is because Rob designed the Reo for that type of batteries and RTD has got the best? Plus the spring in the reo will collapse for safety. idk but someone does :)

Just wanted to say Good Morning Cheri and everyone :)

Good Morning back. I read the links on batteries etc but find it so confusing. Think when RTD opens I will call them. The batteries I have the AW IMR from RTD you can feel the pcb chip in it on top. You can feel the lip in the red covering. I thought of course with mechanical you always have to use a protected battery. And with other regulated mods you don't or don't need to because the mod itself usually provides the protection. Just want a firm understanding on this and if someone could explain in layman's terms I would appreciate it.

The protected batteries have a lithium cobalt chemistry that will produce gas, heat, and flame if the battery is over stressed and goes into thermal runaway. They can't safely discharge the amount of current demanded by low resistance and sub-ohm atomizers. They're better suited for LED flashlights. The protective diodes on these batteries are extra insurance against over-charging/discharging to prevent failure and bad result.

The unprotected batteries we use in vaping devices have lithium manganese and hybrid chemistries that will produce gas and heat if the battery goes into thermal runaway, but flame is much less likely. Also, they can safely discharge much more current and are better suited for low resistance and sub-ohm coils, so the potential for over-stressing the battery is much lower. Adding a protective diode to these batteries would inhibit them from providing the amount of current we want to flow to our low resistance and sub-ohm coils.

All lithium batteries need to be treated with care. Some good rules of thumb are:

  • Measure your battery's voltage frequently before and after recharging
  • Use a "smart" charger that terminates charging when the battery is charged to 4.2 volts
  • Don't discharge your batteries below 3.2 volts
  • Allow your batteries an hour or more to "rest" before and after recharging
  • If the wrapper is torn or frayed, repair it or retire the battery
  • Retire the battery after approximately 300 recharge cycles

In short, if a battery is not listed as Protected, then it is not. The AW IMR batteries Rob recommends for our REO's are not protected. That is not to say that they are dangerous. A Protected lithium ion battery has a circuit board, typically in the base to guard against shorts, overcharge, overdischarge and overheating. They are also slightly longer to accommodate this circuitry. A not Protected lithium ion battery still has a veristor just below the button top that will sacrifice itself in the case of a short, overcharge or overheat condition. Similarly, a not Protected battery, if too overdischarged, is usually toast, whereas the Protected battery will shut down before it reaches that terminal point.

The truth is, both styles are quite safe. The major causes of battery failure are human error and failed chargers. I test mine when they come out and before they go in. I change my batteries several times a day. My I-4 charger sits in a heavy pyrex pie plate with no combustible materials close by. (ie, lampshades or curtains) I also installed a smoke detector in that room. That's it! Take the basic precautions and don't think any more of it.

Good Morning Reo-fam! Got a nice gig digging up a failed water line in a paved lot. Rented a brand new Kubota excavator for the job. Waiting for the last of the utilities guys to come out and mark their lines. Dig lines already chop-sawed. Trench box ready to go in. Good pay day today. Too bad not in time to get a Woodvil. Hopefully it won't be years before the next run. Have a sparkling day everyone.

I think today is going to be your day Ed. When you start digging keep a close eye out for bones. I think Jimmy Hoffa is going to be right there. I can say I knew him "when."
