Custom Drone Battery Cells: What to Prepare Before Requesting a Quote

If your drone design has a fixed battery compartment, send us its dimensions before requesting a quote. A drawing, a weight limit and the expected current draw give our engineers a starting point for checking whether an existing cell fits or a custom design is needed.

What to include in your enquiry

Tell us whether you need an individual cell or a complete battery pack, and what the drone will be used for. For the initial review, please include:

• Dimensions and weight. Share the maximum length, width, thickness and weight. Include the required tab position and any assembly constraints. A drawing or an existing battery specification helps.
• Electrical requirements. List the operating voltage range, charging limits, target capacity (Ah) and energy (Wh), and the expected continuous and peak current. Include how long the peak current lasts.
• Energy density and cycle life. If you have a target in Wh/kg, specify whether it applies to the cell or the complete pack. Include the minimum cycle life and the capacity you need the battery to retain after that number of cycles.
• Operating conditions. Share the expected charging and discharging temperatures.
• Order details. Include the number of samples, expected production quantity and required delivery date.

For a complete pack, include any requirements for the enclosure, connectors, wiring and battery management system. If you are replacing an existing battery, tell us what needs to change. If some specifications are still open, mark them as provisional and identify the ones your design must meet.

Can a custom cell meet both my size and Wh/kg targets?

Our engineers assess your target dimensions and energy density alongside discharge current and cycle life. A higher Wh/kg target can involve a trade-off in cycle life, so include the minimum acceptable cycle count when you submit your requirements. We confirm the minimum order quantity for each proposed custom design.

Joysun’s 28 Ah anode-free cell and 67 Ah solid-state cell are already in mass production. If an existing model fits your requirements, we can discuss samples for that model during the review.

How sampling and approval work

Once we review your requirements, our engineers propose a specification for you to approve before we make samples. We typically retain three to five reference samples and send samples to you for testing in your equipment. After you return the signed sample approval, we schedule production. If testing calls for a specification change, we agree on the revised requirements with you before production begins.

Typical lead times

• Standard-model samples. Within 7 working days.
• Samples with new cell dimensions. Typically 15 working days.
• Standard production orders. Typically 30–45 calendar days after payment is received.
• Custom production orders. Typically 30–45 calendar days after signed sample approval.

Sample lead times are counted from the day after we receive payment or our sales team confirms the sample schedule, as agreed for your order. Production lead times depend on the factory schedule. Please confirm shipping time separately and allow time for customer testing and approval when planning a custom order.

Request a quote

Send your drawing or maximum dimensions, along with your target capacity, weight limit, current requirements and expected quantity. We’ll review the information with you and discuss the next step.
