Frequently Asked Questions

Q: What does the WEMOS D1 Mini Battery Shield V1.1.0 do?

A: The WEMOS D1 Mini Battery Shield V1.1.0 is a dual-function module that both charges a single lithium cell (LiPo or Li-ion) and boosts the output voltage to power your WEMOS D1 Mini board. It accepts a supply voltage of 3.3V–4.2V and operates reliably across a wide temperature range (-40°C to +85°C), making it ideal for portable IoT and microcontroller projects.

Q: How many units can I order, and which should I choose for my project?

A: This Battery Shield is available in quantities of 1PCS, 5PCS, or 10PCS. If you're building a single prototype, 1PCS is a great starting point. For larger production runs or to have spares on hand, the 5PCS or 10PCS packs offer excellent value per unit.

Q: Is this battery shield compatible with standard LiPo and Li-ion batteries?

A: Yes. The shield is designed for single-cell lithium batteries — both LiPo (Lithium Polymer) and Li-ion (Lithium Ion) — operating within the 3.3V–4.2V voltage range. It integrates seamlessly with the WEMOS D1 Mini board's shield stack for a compact, all-in-one power solution.

Q: Does this module require any additional components to function?

A: The Battery Shield V1.1.0 is designed to work as a standalone shield on the WEMOS D1 Mini. You will need a compatible single-cell lithium battery (not included) and a WEMOS D1 Mini board. No complex external wiring is required — simply attach the shield to your board and connect your battery.
