Edna Batteries

The Edna battery box uses a simple 1S1P (3.7v) 18650 li-ion battery pack, with protection circuitry incorporated, and silicone leads. This is a widely available standard format, or can be easily constructed.

Knowing some fundamentals about li-ion batteries (important) will help you get the best from these.

The Edna battery box will also accommodate individual 18650 batteries (typically available up to 3.5Ah), using the Edna battery holder. Source your own batteries.

The latest Edna battery holder will accommodate both unprotected (button top) and protected 18650 batteries.

Always take appropriate care when using individual 18650 Li-ion batteries.
