# BATTERY

* lipo can charge at 1C
|
|
* 5900mAh -> 5.9A
|

|
Strawman design proposal: 1S LiPo, 18650 for easy ubiquitous availability
|
|
(~3,000 mAh). Add cells in parallel until you get the capacity you want.

strawman: charging up to 4v with the INR18650 (see `CELLS:INR18650-35E` for the discharge capacity graph, and `CHARGERS:3` for 4V cutoff w/ a 5V panel) gives us ~3000mAh, or 92% of the battery life.
