This product is either priced at a low wholesale-level price or is a limited quantity product so it is not eligible for any quantity discounts. Quantities ordered will not count towards quantity discounts on other products.

This battery is manufactured under our brand and uses as its main component a genuine Samsung 30Q 3000 mAh battery cell.  This is an amazing cell, extremely low internal resistance similar to the 25R but with a higher capacity of 3 Ah. As always with Liion Wholesale, you can be confident we only use grade A cells in our manufacture.

The cell is made as a flat top from Samsung.  Then we put on a high quality low resistance button top and wrap in a secondary layer of protective PVC.  Please note that this battery lacks PCB protection and therefore IS NOT an approved application by Samsung, so use at your own risk.  These cells can be very dangerous if misused and are only for advanced users who understand how to use and store unprotected cells safely.

These batteries were designed specifically as Thorfire Q8 batteries, but would also work great in any high discharge lighting situation or other application that needs button tops and high discharge.

These are BUTTON TOP batteries and WILL NOT WORK where flat tops are required (Don't know which kind of batteries you need? Please Contact Us before ordering.)


  • Style:  Button Top
  • Size: 18650
  • Approximate Dimensions:  18.65mm x 67.3mm (to tip of button top)

As always, you can trust Liion Wholesale to have tested random samples from each and every batch to make sure all the batteries are fresh and genuine.  Whenever possible, we buy direct from the manufacturer - and we still test our shipments to guarantee authentic, consistent performance. You won't get that with most suppliers.

Battery Warning

Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer, including outside a battery pack and/or without a BMS, may cause severe injury and damage. We are not responsible for any injuries caused by lithium ion batteries - use at your own risk.

All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.

Here are a few tips:

  • Never completely discharge batteries (usually below 2.5V for li-ion or 2.0V for LiFePO4, check datasheet)
  • Charge fully (usually to 4.2V for lithium ion or 3.6V for LiFePO4) before first use
  • Never charge batteries to more than their full charge voltage
  • Do not charge unattended
  • Do not store your li-ion batteries fully charged for an extended period of time (weeks or more)
  • If you must store your battery for a long time, only store in a case or individual box in a cool and dry place at approximately 3.5-3.7V for li-ion or 3.2V for LiFePO4
  • Use only high quality battery chargers
  • Do not expose to heat
  • Do not connect the positive contact to the negative contact without an appropriate load
  • Never exceed the battery's specifications
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries
  • Always charge these batteries on and within fireproof material
  • Never leave rechargeable batteries in a recharging station unattended
  • Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
  • Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases)
  • Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
  • If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
  • If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

Listing claims the INT18650-30Q 15A battery is the Samsung battery, just with a LIION label instead of Samsung. However there is 1 discrepancy that I’m not sure how to reconcile unless it has something to do with adding the button top. The 30Q Samsung’s I own differ in that they are 3.7v where as the LIION INR re-branded version shows 3.6v on the label. Why the difference?

We will see!

Usually Quality batteries. However, as I have learned from other experiences(P26A). We can not possibly rate a battery after Three weeks. Depending on degradation, It can not be judged for at least one year.

  • What device/application do you use this with? Modified X65vn Mini. FLASHLIGHT

Great batteries as always

Batteries came with a case as always. The battery wraps were clean and straight with no damage as expected. USPS was lame, but can't blame that on lion wholesale. Though I do wish they offered other shipping options. The batteries work great in my flashlight.

  • What device/application do you use this with? Thrunite TC15

Only lasted about 4 months.

Purchased these batteries to get a longer run time for a rechargeable flashlight. They worked great for 4 months. After that they will no longer take a charge.. The original battery that that came with the flashlight still works fine. In addition only one of the 2 batteries had the Samsung name on it. when they arrived.

Hi Michael - Thank you for your review. The brand of the battery is typically located under the shipping label that is placed on the batteries. If you remove that label, you will be able to see the "Samsung". We will contact you via email to see if we can assist you with the issue you are having with your batteries.
