This is a CLEARANCE product. No additional quantity discounts will be given. Quantities ordered will not count towards quantity discounts on other products.


Genuine Samsung 30Q 3000 mAh batteries with a low resistance button top welded on.  This is an amazing cell, extremely low internal resistance similar to the 25R but with a higher capacity of 3 Ah.  A great battery for 10-50W per battery devices.  As always, we've done extensive testing to be sure they're real so you can be confident you've got the real thing, grade A.  Then we put on a high quality button top and wrap in a secondary layer of protective PVC.

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, if you are looking for normal flat top 30Q click here.

Note that these cells do not have PCB protection built in, so be sure to treat them carefully as a result.

  • Style:  Button Top

  • Rated capacity:  3000mAh

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.

Details regarding manufacturer ratings here.

Warranty:  Satisfaction guaranteed, if your battery is DOA or you think there's a problem with it just let us know within 14 days of your order and we'll make it right.

Battery safety is very important.  Mistreated batteries can get extremely hot and/or vent which could cause severe injury or even death.  Always follow the following rules to make sure this doesn't happen.  We are not liable for any injuries caused by lithium ion batteries - use at your own risk.

 Here are a few tips:

  • Never completely discharge batteries (below 2.5V under load or 3V unloaded).
  • Charge fully (to 4.2V) before first use.
  • Never use a lot of force on the battery to install
  • 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.  
  • Be mindful of the current limits in the specification and never exceed them.
  • Never keep a spare battery loose in a pocket, purse, etc.  Always use protective cases for loose batteries.  If it shorts against a piece of metal it can be very dangerous.
  • Never charge battery 4.3V or above.
  • 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 battery then do it in a case or individual box in cool and dry place at approximately 3.6V - 3.7V.
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for Li-ion batteries.

    • What device/application do you use this with? Used in a TK61vn modified search light, 1800Lumens/770Kcd!

    Great batteries, nice wholesome BT!

    30Q are known as great batteries. The only question is longevity. In that sense,,,time will tell. Personally I think reviews should be done several months after the product is used. Since they are not, I can say they perform very well at the moment!

    • What device/application do you use this with? TK61vn V4 -1800 Lumen/770Kcd

    Still working well,,,as expected!

    After 2 months of use in my TK61vn V4[1800 lumen/770Kcd] they are still working great.. The voltages are holding well with minimal loss after resting several days.Only losing 0.01v/0.02v maximum. I see that Jon just lowered the price from $6.49 to $5.09 which is what I paid with the Group Buy price on BLF! I want to get some more but do not need any! I already have ["new"] 4 x 30Q FT that have been in storage for 10 months that I bought from Liion last October. Maybe one of my single cell Modified torches will need some of these BT's before they sell out! If I remember, I will give an update in about 1 year. I am sure they will still be performing very well.
