52V Battery for Electric Bike

Get smoother hill-climbs and stronger acceleration than 48V, with lower voltage sag under load. Our 52V packs are built for dependable daily riding and performance builds alike. Whether you need long range or high current, we engineer and test packs with Grade-A cells (21700 EVE 50E / Samsung 50G; 18650 DMEGC 2600/3000 / Samsung 35E), tight cell matching, and integer BMS options (30A / 40A / 50A / 60A / 80A / 100A). Connectors can be XT60/XT90 or 2-pin leads as housing allows.

52V (14S) E-Bike Battery Packs — High-Output 21700 & 18650 Builds

Step up from 48V without changing your platform. Our 52V packs boost top speed and hill-climb while staying compatible with most 500–3000W controllers. We manufacture 10.4–45Ah configurations in two cell classes: 21700 (EVE 50E / Samsung 50GB) for high energy and strong current, and 18650 (DMEGC 2600/3000 / Samsung 35E) for cost-optimized reliability.
Each pack is built with Grade-A cell matching, robust busbars, and a smart BMS (50A or 60A) providing full protections (over/under-voltage, over-current, short-circuit, temperature). Bluetooth is optional by model, and we support XT60 or XT90 leads. Tell us your target current, dimensions, connector, and desired range—our engineers will configure the exact 52V solution for your build.

More Headroom vs 48V

Higher voltage means lower phase current for the same power, reducing heat and voltage sag for better hill-climb and acceleration.

Flexible Builds

21700 for high energy density (range) or 18650 for broad availability; capacities from 10–40Ah across multiple housings.

Integer BMS, Real Power

Comprehensive safety—over-charge/over-discharge, over-current, short-circuit, and temperature monitoring—with optional Bluetooth for live pack diagnostics.

Drop-In Integration

XT60/XT90 or 2-pin leads, CC/CV 58.8V charging, harnessing and busbars designed for low resistance and stable output.

52V 14S E-Bike Batteries — 21700 & 18650 Options

Choose your capacity (10–45Ah) and preferred connector (XT60/XT90). Plug into your 52V controller for cleaner climbs, stronger mid-range torque, and reliable daily use.

Why Junda Battery

Custom Battery Engineering (OEM/ODM)

We design lithium battery packs to your exact spec—voltage (24/36/48/52/60/72V), capacity, discharge current, dimensions, connectors, and BMS logic—across LiFePO4 and NMC, 18650/21700/prismatic cells. Share drawings or targets (e.g., 48V 20Ah, 60V 50A BMS) and we deliver a fit-for-purpose pack for e-bikes/e-motos, cargo, robotics/AGVs, marine, and storage.

Premium Components & Cell Sourcing

Grade-A cells from trusted brands (Samsung 50G, EVE 50E, DMEGC 2600/3000, etc.), high-reliability integer BMS (30A/40A/50A/60A/80A/100A), nickel/copper busbars, and robust harnessing keep voltage sag low and output stable. Traceable lots and consistent quality mean longer cycle life and predictable performance.

Advanced Manufacturing & Quality Control

Cell grading & IR-matching, laser/smart welding, insulation & dielectric checks, and 100% end-of-line verification (capacity/IR; cycle sampling). BMS functional tests and documented QC deliver precision, consistency, and safety—pack after pack.

End-to-End Technical & Compliance Support

From early design through shipment, we provide application engineering, thermal advice, connector/charger matching, and documentation. We support UN38.3 transport testing and market compliance (CE, IEC 62133-2), plus DG packaging, logistics, and responsive after-sales—so your packs arrive ready to integrate and perform.

52V e-Bike Battery FAQ

Covers our 52V (14S) packs in 30–45Ah using Grade-A 21700 cells (EVE 50E / Samsung 50GB), standard 60A BMS, 3A charger by default.

1) What does “52V” actually mean?
A 52V pack is a 14-series (14S) lithium-ion battery. Nominal voltage ≈ 51.8 V, full charge is 58.8 V, and typical BMS cut-off is ~39–42 V depending on settings.
2) Which motors/controllers are suitable?
With our standard 60A BMS, a 52V pack supports controllers up to about 3 kW (52 V × 60 A ≈ 3,120 W). It pairs well with 500 W–3,000 W hub or mid-drives. If your system requires more, consider a 60V/72V pack or request a custom high-current build after we confirm your controller specs.
3) How far can I ride on one charge?
Estimate range with: Range ≈ (Ah × 51.8 V) ÷ Wh/km.
52V 20Ah ≈ 1,036 Wh → ~86 km @ 12 Wh/km (~54 mi)
52V 40Ah ≈ 2,072 Wh → ~173 km @ 12 Wh/km (~107 mi)
Real range varies with rider weight, speed, terrain, temperature, and assist level.
4) What capacities and cell options do you offer?
Standard options: 30Ah / 35Ah / 40Ah / 45Ah built as 14S6P / 14S7P / 14S8P / 14S9P using EVE 21700 50E or Samsung 50GB 21700 Grade-A cells. We can recommend the best pairing for your controller and range target.
5) What protections does the BMS provide?
Our BMS includes over-charge, over-discharge, over-current, short-circuit, and temperature protection with balance management. 60A continuous is standard; Bluetooth/app monitoring can be added on request for compatible models.
6) Which discharge connectors and charge ports are available?
We match your controller on order—XT60 / XT90 are most common for discharge. Charge port options include DC 5.5×2.1 or aviation plug. If you’re unsure, send a photo of your controller plug and we’ll configure it to fit.
7) How long does charging take?
Time ≈ Ah ÷ charger-A × 1.15 (for CC/CV taper). With our default 3A charger:
20Ah → ~7.7 h
35Ah → ~13.4 h
40Ah → ~15.3 h
Faster chargers are available if your pack and use-case allow.
8) Can a 52V battery replace my 48V battery?
Sometimes. Your controller must tolerate 58.8 V fully-charged voltage (often labeled ≤63 V components). Check the controller spec or capacitor rating. If uncertain, ask us—otherwise use a 48V pack.
9) What are the recommended storage and care practices?
Store at 40–60% state-of-charge, in a cool, dry place (≈10–25 °C). Top up every 2–3 months if idle. Avoid leaving the pack fully charged or fully depleted for long periods. Keep vents dry and avoid pressure-washing.
10) Do you support certifications and safe shipping?
Yes. We support UN38.3 testing and DG packaging for air/sea transport, and can provide MSDS and related compliance documents. Ask us about regional requirements (e.g., CE/IEC) for your market.
