hi guys,
on your “Sunny Buddy MPPT Solar Charger” is says that it’s for single cell LiPos only. But on your tutorial “Weather Station Wirelessly Connected to Wunderground” it’s connected to a 3 sell LiPo. Why is that? Is this advisable?
The sunny buddy is intended for single cells but could be possible with particular muli-cell units. While it is possible; it is not supported, recommended, or guaranteed. Please use at your own discretion.
Thanks for your reply. Is there a solar charger available or in development that is intended for multi-cell units?
As I am currently aware, there are no projects planned for this at this time. I will forward your feedback to our internal teams for future products.
Great, thanks Brandon.
Also, the 3 cell pack we used for that project has all the cells in parallel and that effectively makes it a single cell pack so it will work with the Sunny Buddy.
When the cells are wired in series is where things get more difficult as far as charging goes.
