All are sold. Thanks CPF!
Hi All,
I have received several requests for my datiLED battery drainers, and finally got around to putting some together using my new PCBs. The new "Volt Vamp" battery drainers are more efficient than my previous builds due to a higher quality inductor and improved board connections. They also use a higher grade N52 Neodymium magnet for the contacts, allowing them to be mounted to vertical surfaces when using an AA or AAA battery.
The low profile Volt Vamp will drain a battery to less than 0.8V while providing usable light. It will continue to light the LED to approximately 0.65V with declining brightness. They are especially good at draining "dead" cells, or what I prefer to call "partially depleted".
The Volt Vamp battery drainers feature:
Nichia GS COV bin LEDs.
High quality N52 grade neodymium magnet connections. The ground connection has 3 pounds of holding force.
Teflon jacketed silver plated copper stranded wire, mechanically anchored on both ends with solder and epoxy.
Epoxy encapsulated components for durability and environmental protection.
Works with any 1.5V cell. DO NOT use with CR123 or rechargeable cells.
Ideal for power outages, camping and travel.
Easily fits into Altoid tin emergency pack, bug out bag or luggage.
Can be anchored to any ferrous metal surface. Will support an AA cell on a vertical surface, or suspended from the ceiling. Note: Some cheaper alkaline or carbon zinc cells are not made with steel contacts.
There are a total of 12 8 0 available. $14 each, or two for $27. The first "I'll take it" posted in this thread takes preference over other communication. Price listed includes First Class postage within the U.S.
A word of caution about the neodymium magnets used in the battery drainers; they are unusually strong, and will jump to magnetic and ferrous objects. Neodymium magnets are brittle, and could crack or shatter if allowed to slam together. Neodymium magnets can affect electronic devices if allowed to come into contact.
