I’m working on a project that requires 2 weeks of battery backup in the event of a power failure.
Question 1 - what’s the tolerance on the PSU voltage of a Seeeduino ? ie - when will it blow up, when will it cease to work ?
Question 2 - Has anybody any experience integrating LARGE Amp Hour batteries into Arduino projects and also managing the charge of these large batteries ?
Would love to hear peoples thoughts.
Thanks in advance
