Pimoroni Zero LiPo - supply voltage range


#1

I have a Pimoroni Zero LiPo and have a couple of 3.7 volt LiPo batteries, but am waiting for some connectors in the post.

In the meantime, I do have some 7.4 volt Lipo batteries and have the right connections, however, I am a bit wary of connecting one to the Zero LiPo, as I cannot find the acceptable input voltage range for it.

Can you tell me what the range is and would a 7.4 volt LiPo be safe?

the Zero LiPo features a TPS6123x, a boost-only converter, so the max you probably can feed through is 5.25V. I think anything above that would destroy the Pi… I certainly wouldn’t try.

actually, our engineer pointed out that the converter datasheet state a max rating of 5.5V, so it’s possible you’d destroy more than the Pi too:

Thank you for your advice,
I’ll wait for my 3.7volt connectors,
