Q&A
- What country were these batteries made do you have any 18500 battery cells made in Japan Thank you for your time and help with this information request
- We do not carry any 18500's made in Japan - these batteries are made in China. Many lithium ion batteries are made in China.
- I would like to know if an 18500 size cell is available with a continous discharge rate of 8-10 ampS or I would like to exchange these cells for 18650 size and am requesting an RMA number.
- We do not have the information on that from the manufacturer. Sorry.
- I would like to know if an 18500 size cell is available with a continous discharge rate of 8-10 amps is available or if you sell the sony vc3 ( original size for the solowheel unicycle) or samsung 22p which are used in electric unicycles? My original battery is not branded but uses 16 18500 cells vs the 18650 size. Why do the 18500 cells not be able to produce a similar discharge rate than the ones only 15mm longer according to the cell specs of similarly built 18650's?
- The Panasonic 18500 does not provide us with a discharge rate for this battery. The Olight 18500 we carry is proprietary so would not work for any device but the light it is meant to be used in.
- I need to change the original cells in an Airwheel X3 electric unicycle with a 350W motorand would like to know if Panasonic 18500 2040mAh 3.6V Unprotected Lithium Ion (Li-ion) Flat Top Battery have sufficient discharge capacity? The original cells do not appear to have any markings on them
- I am afraid we know nothing about the Airwheel so cannot advise on batteries. Sorry.
