I cant power up an ESP-01 with my 3.7v 1400 mAh Li-Po battery which could i fly drone.
İs there something wrong ?
i did measure the voltage and amps with a multimeter and i observe when i connect the pins Voltage drops to 1.4 but there is no drop when i connect them to a arduino's 3.3v. İs there a porblem with this battery ? or will all batteries behave like this ? where do i wrong ? what should i do for run it with a battery ?
Thanks in advance and best regards
