Protected 5000mAh 10A 21700 Button Top Battery - Wholesale Discount

Important: Like other protected 21700 these batteries are too long to fit into many chargers. However, they can be charged using the XTAR FC2 charger, or other chargers that fit batteries that are on the long side.

The LiionWholesale Protected 21700 5000mAh is a PCB protected button top battery.  This is a 5000 mAh 10 A battery and is one of the best batteries we offer for high discharge flashlights or other devices that need a high capacity but medium discharge protected battery.  

Compatible with 3.7V

Some companies market batteries like this as 3.7V 3500mAh, this will replace any 3.7V lithium ion with no issue.  3.7V vs 3.6V is just a labeling difference and is not an actual voltage difference inside the battery.

All protected batteries are not the same - the Liion Wholesale version is the best protected 21700 on the market

These are manufactured with a very high quality PCB including a Japanese Ricoh protection IC with three FNK MOSFETs for 20A high current cutoff (most PCBs will not be able to handle this much current).   This protection circuit protects the battery from mishandling, overcharge, or overdischarge while allowing the battery to do its job properly.

The cell is made by a high quality cell manufacturer.  Our company then adds the high quality PCB along with the button top in an ISO certified factory to all safety standards.  A silver wrap is put over the top to hold it together.

Please note that these batteries have a UN38.3 test report available and are legal for shipping.  Many protected batteries on the market actually do not have any test data and are likely illegal for shipping due to lack of UN38.3 test report.  Many competitors don't realize that a separate test needs to be done on the battery assembly and that the cell test is not enough.  All of our batteries include a UN38.3 report available upon request.

One of the tightest diameter protected 21700s

We took great pains to minimize the diameter and keep it to 21.7mm maximum so it can fit in as many devices as possible.
