This is a PROMOTIONAL product, with LIMITED quantities available.
NO additional quantity discounts or wholesale 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 authentic so you can be confident you've got the real thing, grade A.
The cell is made as a flat top from Samsung. Then we put on a high quality button top and wrap in a secondary layer of protective PVC.
IMPORTANT: DO NOT REMOVE THE OUTER 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 and WILL NOT WORK where flat tops are required - if you are looking for normal flat top 30Q click here. (Don't know which kind of batteries you need? Please Contact Us before ordering.)
Note that these cells do not have PCB protection built in, so be sure to treat them carefully as a result.

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.
Batteries are sold individually.
If your battery is damaged or defective on arrival (will not take its first charge, or has issues with its first cycle), please let us know within 14 days of receiving your order and we'll make it right. Please read our complete store policy on defective products here for more information and to see if you're eligible.

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 (below 2.5V under load or 3V unloaded)
- Charge fully (to 4.2V) before first use
- Never charge batteries to 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 your battery, only store in a case or individual box in a cool and dry place at approximately 3.6-3.7V
- 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

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!
Robert, we'd love your re-review in a few months :). Feel free to post again when you've had the opportunity to use them for a while.
I just received the batteries so I can't speak to the longevity of the charge but so far (3 days) they seem fine.
Samsung 30Q offers a nice balance between capacity and high discharge rate. These have a button top added by Liion Wholesale and seem to be assembled and wrapped well, with a nice branded black wrapper bearing the specs of the battery. All vital specs tested well and matched or exceeded published specs for Samsung 30Q.
Good product great price
After using it for a while they hold their charge as tested with opus so happy with my purchase. This site was recommended by a YouTuber anyway so I felt comfortable buying from here.
