Autonomous Mobile Robot (AMR) & Delivery Robot Battery FAQ

High energy-density Lithium-ion is the industry standard for unmanned delivery. When selecting the optimal battery type (such as 18650 or 21700 cell types), you must evaluate payload capacity, terrain, and operating temperatures. As a vertically integrated 20-year source factory, KRL engineers custom lithium solutions that perfectly align with these complex variables to ensure maximum fleet endurance.
A comprehensive cost analysis must look beyond the initial purchase price. KRL batteries are engineered to deliver 2000+ lifecycles—offering up to a 150% longer lifespan than standard market alternatives. Combined with zero daily maintenance and advanced BMS fault prevention, our vertically integrated manufacturing significantly lowers long-term replacement and operational costs.
Scaling a robotics project requires uncompromised supply chain stability. Partnering directly with KRL—a 20-year vertically integrated source factory—guarantees total quality control from initial cell type selection to final assembly. We eliminate middleman markups and offer deep customization capabilities, providing you with a massive competitive edge in the automated logistics market.
A Smart BMS transforms a standard power pack into an intelligent, communicative asset. It is essential for monitoring real-time State of Charge (SOC) and State of Health (SOH) via CAN/RS485 or SMBus protocols. This allows your fleet management software to optimize routes, balance cell performance, and prevent thermal issues, ensuring stable 24/7 operation in dynamic outdoor environments.
Attribute Lithium-Ion Lithium-Polymer

Shape Flexibility Limited Very flexible
Weight Low Lower
Cycle Life Long Medium–long
Cost Medium Slightly higher
Safety Good Good with proper BMS
The right approach depends on your specific logistics model. For continuous, zero-downtime operations, KRL's custom hot-swappable battery designs allow operators to change packs in seconds. Alternatively, our high-rate lithium packs support 1–2 hour ultra-fast charging, ideal for opportunity charging at docking stations between scheduled delivery runs.
A smart battery typically includes features such as:
