Title: Use a EEMB 3.7V 2000mAh 103454 Lipo Battery to power ESP32-H2-DevKit-LiPo
Post by: m4biz on August 30, 2024, 01:11:29 PM
Hi.
I'd like to purchase an ESP32-H2-DevKit-LiPo.
Anyway I've read that it works with a BATTERY-LIPO1400mAh.
The question is : is mandatory to use this 1400 mAh LiPo battery or, having already an EEMB 3.7V 2000mAh 103454 Lipo Battery, I could use it without purchase another?
Thanks in advance for your help.

Usually there is no problem to charge Li-Ion with Li-Po charger, but double and triple check where is the plus and minus on the connector and on your battery. There isn't universal standard and these might be mirrored which would lead to short circuit!

If in doubt consider checking the schematic and double checking the datasheet of the battery charger IC BL4054B-42TPRN:
