POLEEJIEK’s electric bike batteries are tailored for B2B retailers, e-bike manufacturers, and urban fleets, delivering high-capacity lithium-ion solutions. Unlike our 3 wheel e-bikes designed for stability or compact mini bikes for urban mobility, our batteries, like the EBK-48V, offer 36V–48V systems with 10–25Ah capacities and smart BMS for enhanced performance. For specs, see our Battery Guide. These batteries power urban delivery fleets, bike-sharing programs, and OEM production.
Our electric bike battery 48v models provide 20–65 mile ranges and 500–1000 charge cycles, ideal for high-power e-bikes in commercial fleets. Compared to heavier lead-acid alternatives, our lithium-ion batteries reduce weight and enhance efficiency for commuters and delivery services. Certified to global standards, they ensure reliability for B2B partners—see certificates.
For manufacturers, our electric bike battery replacement options are modular, fitting road e-bikes, cargo e-bikes, and folding e-bikes. Retailers benefit from bulk supply of 36V and 48V batteries, supporting electric bike conversion kits with battery for aftermarket upgrades. Our 30,000 sqm factory delivers customized solutions in 45–60 days.
Our batteries for electric bikes support motors up to 750W and comply with U.S. and EU regulations, featuring waterproof housing and 18650 cells for durability. Maintenance tips extend lifespan to 2–5 years, ideal for high-turnover fleets. Compatibility covers most e-bike systems across road, cargo, and folding platforms.
