Frequently Asked Questions
What payment options are available?
We accept UPI, debit cards, credit cards, and Cash on Delivery (COD) across India. Choose at checkout based on your convenience.
What is the typical charging time?
With a 0.1C charger (32mA), expect 3–4 hours to full charge. Higher-current chargers (0.5C or 1C) reduce this to 45–90 minutes, but require proper circuit protection to avoid damage.
Where do you ship?
We ship across India including Delhi, Mumbai, Bangalore, Hyderabad, Chennai, and Pune. Standard delivery takes 3–5 business days. Express options available at checkout.
Can I use this battery with Arduino or ESP32?
Yes. Connect via a protection circuit or charging module like TP4056 to prevent over-discharge. Ensure your microcontroller has voltage regulation rated for 3.7–4.2V input.
