Best 20700 Battery for Vaping 2020 – Reviews & Top Picks

For a vape mod to operate smoothly and safely, it must be powered by a reliable battery. 

In the past, vapers were content with the power output of the 18650 batteries. However, as time passed, they wanted more power. 

As a result, many manufacturers tried to capitalize on the growing demands of the vaping community, thus developing 20700 batteries. Truth be told, 20700 vape batteries are relatively new, only appearing for the first time in 2017. 

Compared to a 18650 battery, a 20700 battery performs at a much higher wattage range and has more power, better performance, and longer battery life. Such is the power of 20700 batteries that they are even used on cordless power tools, flashlights, and electric vehicles. 

There are various factors you need to consider when selecting a 20700 battery, including the discharge and voltage rates, peak voltage, and battery capacity. I would also advise you to only purchase these batteries from a trusted source. 

Why so? Some sellers inaccurately exaggerate the battery specs to attract customers, and some even sell rewrapped batteries. 

Anyway, let’s get to the matter at hand. Check out this list of some of the best 20700 batteries for vaping.

Top 5 Best 20700 Battery for Vaping 2020 – Our Reviews:

1. AmpKing 20700 Battery

With a whopping power output of 40 amps, AmpKing’s 20700 battery is truly a monster in disguise. 

Featuring five-leg top contacts, it is capable of supplying sufficient power for vaping on both variable wattage and mechanical mods. I also like the fact that the battery has an enviable storage life. 

For a battery as powerful as the AmpKing 20700, it is quite surprising that it is lightweight too. 

However, be careful not to expose this battery to e-juice; it can soften and swell up if you do. Apart from that, the AmpKing 20700 has all the makings of a superb battery for vaping. 

Pros

  • Power output of 40 amps
  • Five-leg top contacts
  • Lightweight
  • Long battery life
  • High-energy density

Cons

  • Susceptible to overheating
  • Has a long recharge time
  • Can swell up when exposed to e-juice

2. IJOY 5-Leg Battery

As its name suggests, the IJOY 5-Leg boasts of five-leg top contacts. 

What I like about the IJOY 5-Leg, in particular, is the flat-top design that makes it ideal for both variable voltage and variable wattage mods. In fact, the IJOY 5-Leg performs admirably in any mod with high power configurations. 

Featuring a 3000mAh rating, this battery enjoys a significant fan following from all over. Go for it if you want to enjoy a high-powered vaping session for an extended period. 

Pros

  • Flat-top design

Cons

  • Wrapping starts peeling off after a while
  • Some users have complained that it doesn’t hold a charge after a few uses

3. Sanyo NCR20700B Battery

No one beats the Japanese when it comes to releasing high-quality, trustworthy batteries on the market. 

Sanyo‘s NCR20700 rechargeable battery is particularly loved by fans and critics alike for its reliability. It works exceptionally well in both variable voltage and variable wattage mods. 

Like other premium 20700 batteries, the Sanyo NCR20700B also has outstanding battery life. In fact, on a full charge, this battery is capable of lasting throughout the day. 

Try the Sanyo NCR20700B if you enjoy low-wattage vaping. 

Pros

  • Particularly great for low-wattage vaping
  • Reliable power output
  • Phenomenal battery life

Cons

  • Not as powerful as other 20700 batteries
  • Not ideal if you’re looking for strong potent hits on the regular

4. Hohm Tech Sherlock Battery

Thank goodness the Hohm Tech Sherlock doesn’t tarnish the legacy of the fictional character it was named after.  

Featuring a power output of 48 amps and a large 3116mAh capacity, the Hohm Tech Sherlock is a high-amp rechargeable 20700 battery ideal for those looking to vape up to 75W per cell. This battery is at its best when used on regulated vape box mods

Hohm Tech Sherlock is famous because of its accessibility and excellent output. However, be advised that Hohm Tech discourages the use of the Sherlock on unprotected mechanical mods. 

Pros

  • Power output of 48 amps
  • Quick charging
  • Large battery capacity
  • Outstanding choice for mods with high-power configurations

Cons

  • Could’ve been priced cheaper
  • Susceptible to overheating

5. Efest 20700 Battery

The Efest 20700 battery is a dark horse entry to the list. It may not be as popular as some of the batteries mentioned above, but it is well capable of giving any 20700 battery a run for its money. 

The Efest 20700 battery’s flat-top design makes it an ideal choice for high-powered vape mods. 

Other features of the battery include Hi-Drain capability and the ability to produce 30A of power efficiently for up to 3000mAh of capacity. It also performs similarly to the IJoy 20700. 

The Efest 20700 battery is, without a doubt, a safe investment in my book. 

Pros

  • Hi-Drain capability
  • 3000mAh power capacity
  • Flat-top design

Cons

  • Could’ve been priced cheaper

Conclusion

There isn’t a dearth of 20700 batteries on the market. However, the ones worth purchasing are few and far between. 

Some batteries are even re-wrapped and have their battery stats fabricated to appear impressive. So, always be extra alert when purchasing a 20700 battery. 

Only purchase from a trusted source. 

For whatever reason, big-name brands such as Samsung, LG, and Sony don’t have 20700 batteries available for purchase yet. That means if you find a Samsung, LG, and Sony 20700 battery online, chances are it is a counterfeit battery. 

On the bright side, the lack of involvement from popular manufacturers has given smaller brands a chance to prove their worth. 

If you want a 20700 battery that is powerful yet lightweight, go for the AmpKing 20700 battery. For those that prefer low-wattage vaping, opt for the Sanyo NCR20700B as it will give you satisfactory results.
