I picked up a glass jar that I wanted to put a Teensy LC in along with some neopixels/ws2812b's, and I'm looking around for a lipo battery that I could use. The dimensions of the jar are 3" long and 0.7-0.8" wide. Most of the lipo batteries that I'm familiar with are too wide for the jar, or only have 100mah of power. A 600mAh would probably be fine (giving me maybe 6 hours of run time). Ideally, with any battery, the standard lipo chargers (the onehorse Teensy charger or the Adafruit pro trinket backpack charger) would work.
A 18650 battery will fit, but it is rather tight with a teensy and only one set of LEDs would fit in the jar.
One AA or two AAA batteries will fit, and I could use a current booster to get up to the 3.5-5.5v needed for neopixels. I figure rechargeable AAA's are around 800mAh and AA's are around 2200mAh, which would give me 3.5 hours of runtime on the AAA's and 4.5 hours on the AA's (assuming 90% efficiency conversion, 100mA power draw of the Teensy + LEDs).
Does anybody have suggestions of an appropriate sized battery to use?
