Q: 3. Will these work in the Surefire R! Lawman flashlight?

Q: 4. Does this work with the Tilta Advanced ring grip handle?

Q: 5. Will these fit in the Moza Air 2 battery compartment? I have read where the batteries that come with the Moza are smaller than standard 18650Li so any other branded battery you buy to replace it will be too big and will not fit. If this battery is sized too big for that product, then is there any other 18650 battery on the market that's smaller than standard size to fit in the Moza Air 2? Because the Moza batteries died on me (and many other people in the reviews section) and I don't want to replace them by again buying the same faulty battery it comes with. Anybody have any knowledge on this unique issue?

A: I contacted Gusden (the manufacturer of the Moza Air 2) concerning your inquiry. Unfortunately, they state they cannot guarantee the performance of the SureFire 18650 Li-Ion Rechargeable Battery with Charging Port (3.6V, 3500mAh) in the Moza Air 2 gimbal. They instead recommend the customized Moza Li-Ion Battery for Moza Air 2 (4-Pack), B&H # MOMCG7, for use in the Moza Air 2, and cannot guarantee compatibility with the Surefire battery option.

Q: 6. How to check if this battery will fit your device? It is showing dimensional differences than other 18650 batteries.

A: Being that these batteries match the dimensions of the Nitecore 18650 batteries, it will work in any device that normally accepts those batteries.

Q: 7. what is the max and constant discharge rates?

A: I'm sorry, but the manufacturer does not provide that information. However, this will work for any typical camera, typical add-on camera flash, typical toy, or typical small appliance such as a flashlight or portable audio recorder. If you believe your intended usage is one of extra high draw then you might want to discuss your needs with the manufacturer of the equipment you are using to see what they recommend. Either way, all batteries do have some internal impedance so you can expect any battery to become warm during use -- especially rechargeables due to their ability to allowance for higher draw than alkaline or carbon-zinc chemistry batteries.

Q: 8. Will these work with the Moza Air 2 or are they too long?

A: No, the Watson 18650 Rechargeable Lithium-Ion Battery (3.7V, 2600mAh) are too tall to fit in the Moza Air 2's 18650 battery bay. We can only recommend using the Moza Li-Ion Battery for Moza Air 2 (4-Pack), BH #MOMCG7, to power the Moza Air 2. See: https://bhpho.to/2rlLU0d
