We collected thousands of real consultation records from Keeppower global battery FAQ page, and selected 8 core questions that puzzle most buyers. All answers are combined with our actual production cases and international battery safety standards, totally different from generic online template replies.
FAQ 1: What is the difference between Li-ion, Li-Polymer and LiFePO4 custom battery packs? How to choose?
This is the No.1 question raised by new OEM clients. Three mainstream lithium battery chemistries have obvious differences in application scenarios, safety performance, cost and service life, and Keeppower matches the most appropriate solution according to clients’ actual usage scenarios.
-
Li-ion Battery: Cost-effective, complete model coverage. Keeppower covers 99% of mainstream Li-ion battery models on the market, suitable for power tools, consumer electronics and general portable devices. It is also the core product involved in the hot 2026 battery trend:21700 lithium-ion batteries replacing 18650 cells.
-
Li-Polymer Battery: Ultra-thin, flexible and customizable shape, no hard shell limitation. Perfect for wearable devices, medical equipment and slim handheld products with strict space limits.
-
LiFePO4 Battery: Highest safety performance, ultra-long cycle life, excellent high and low temperature resistance. The best choice for outdoor energy storage, industrial robots and backup power systems.

FAQ 2: What certifications do Keeppower custom battery packs support for global export?
Cross-border shipment failure caused by missing certifications is one of the biggest procurement pain points. All Keeppower custom lithium battery packs are produced under ISO9001:2015 quality management system, and have obtained full-range authoritative certifications including UL, CB, IEC, UN, CCC, ETL, CE and RoHS. All certification reports can be provided before shipment to ensure smooth customs clearance in Europe, North America, Southeast Asia and other regions.

FAQ 3: How long is the lead time for custom battery pack orders? Can you support urgent orders?
Order delivery cycle is the core factor affecting customers’ product launch schedule. Benefiting from mature production lines and standardized production processes, Keeppower keeps a stable delivery record for 15 consecutive years: 95% of standard custom battery orders can be shipped within 1 week.
We support urgent order services for clients with tight project schedules. Our quick response team replies to all technical inquiries and order feedback in the shortest time, avoiding communication delays. If you have urgent batch procurement demands, learn more about our fast production process via fast turnaround custom lithium battery pack service.
FAQ 4: What detailed parameters do I need to provide for battery customization?
To make accurate and compliant custom lithium battery packs, clients only need to prepare 5 key parameters: rated voltage, required capacity, external dimension limitation, working current (continuous and peak current), and matching interface type. Our engineering team will complete cell matching, BMS design and safety testing independently without extra work from buyers.
FAQ 5: Why cannot I match cheap third-party 12V power adapters with custom lithium batteries?
Many buyers choose low-cost uncertified 12V power adapters to save procurement cost, but this behavior will bring irreversible hidden dangers to high-quality custom battery packs. Unmatched voltage, poor surge protection and unqualified internal components will lead to battery bulging, shortened service life and even safety accidents.
We strongly recommend all OEM clients to read our popular industry article: 5 hidden risks of choosing the wrong 12V power adapter manufacturer before purchasing supporting chargers and adapters, so as to eliminate potential safety hazards in advance.
FAQ 6: Does Keeppower provide professional battery solutions for drone equipment?
Yes. Drones are one of our core application scenarios for high-discharge custom battery packs. Our professional drone batteries support long endurance flight, stable high-current output and strong shock resistance, helping aerial devices realize longer shooting time and more stable mission execution. You can view professional cases via drone dedicated custom battery power solutions.
FAQ 7: What is the advantage of Keeppower Q4 custom battery service compared with other suppliers?
Most battery customization processes on the market are cumbersome with repeated communication and long prototype cycles. Keeppower independently launched Q4 exclusive custom service, aiming to build the most streamlined one-stop custom battery pack process in the industry. It simplifies communication links, shortens prototype confirmation cycle, reduces extra communication costs, and provides full-process technical tracking from design, sample production to mass production.
