T-PCIE / T-SIM7000G using unchargeable Lithium Battery

[vitorxlima]

Hi, i need to use a Lithium battery ER26500 3.6V-9000mAH on models T-PCIE and T-SIM7000G replacing 18650 slot. This battery isn't chargeable, i'm woried about the charge module when use USB-C or UART individuals pins to program, and damage the battery or the board.

I do not need the recharge function in this case. There's a easy ways to solve this problem?

@vitorxlima Easy! Put a diode in series with the non-rechargeable battery to allow the battery to dis-charge and run the board but not allow the USB to pass current to it.
