This rechargeable lithium polymer cell is thin and light, and includes protection circuitry.* It's polarized correctly for use with the Timeport and is the perfect size to power your portable projects. At 1.25" X 1.5", it fits between the Timeport spacer mounts and will power the unit for hours. The output ranges from 4.2V when completely charged to 3.7V
SKU: HC93337
Additional Details
The connector is a 2-pin JST jack.
*The included protection circuitry protects the battery from over-charging or over-use. Discharge cuts out when the cell reaches 3.0V. It will also protect against output shorts.
It is very important that you re-charge the cell only with a Lilon/LiPoly constant-voltage/constant-current smart charger at a rate of 500mA or less. The Heron Circuits Timeport, powered by either of the 6V or 9V AC/DC adapters sold on this site, is perfect for the job.
Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger to charge this cell. Do not short, bend, crush or puncture the cell. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or possibility of short circuits, and never use or charge unattended. The polarity of the connector for this cell matches Heron Circuits PC boards; other brands may have reverse polarity and can destroy the charging circuitry. Lithium ion polymer cells and batteries should be used by an experienced person who is comfortable working with power supplies.
