Reoaoone DCH Series Internal Folding E-Bike Replacement Battery –

36V / 48V / 52V System Configurations (DCH-003, DCH-006, DCH-009 Cases) for 350W to 1000W Motors (Smart BMS, Key Lock System & Slim In-Frame Profile)

Restore full range and peak speed to your folding electric bike with the Reoaoone DCH Series Internal Lithium-Ion Battery. Specially engineered to slide directly inside the main frame tube of popular folding e-bike models, this hidden battery configuration maintains your bike's original factory look while protecting the battery cells from weather, dirt, and road vibration.

Compatible with motor power ratings from 350W to 1000W, the Reoaoone DCH series is available in DCH-003, DCH-006, and DCH-009 housing profiles ( physical sizes). Whether replacing an aging factory pack or upgrading capacity, each battery features an internal Smart BMS, charging port, handle, and key lock mechanism for anti-theft protection.

⚠️ Dimensions & Compatibility Check

CRITICAL SELECTION INSTRUCTION:

• Verify Frame Length: Measure your existing folding e-bike's internal battery cavity or current battery sleeve. Case options come in two standard lengths: .

• Voltage Compatibility: Choose the exact voltage required for your controller (36V, 48V, or 52V). Do not select a higher voltage unless your motor controller explicitly supports it.

• Motor Power Rating: Engineered to support mid-drive and hub motors from 350W up to 1000W.

🚀 Key High-Performance Features

• Hidden In-Frame Integration: Slides neatly into the central frame fold cavity for a low center of gravity and a clean OEM profile.

• Integrated Key-Lock Security: Built-in lock mechanism secures the battery inside the frame to prevent theft when parked.

• Multiple Voltage & Capacity Options: Offered in 36V ($10\text{Ah–}15\text{Ah}$), 48V ($10.4\text{Ah–}17\text{Ah}$), and 52V ($12.5\text{Ah–}17\text{Ah}$) to match your original motor specs.

• Integrated Smart BMS: Protects cells against overcharging, over-discharging, short circuits, and thermal conditions.

• Retractable Pull Handle: Equipped with a fold-out handle to simplify battery removal for off-bike indoor charging.

• CE Safety Certified: Tested to comply with European micro-mobility safety standard frameworks.

FAQ

Q: What type of electric bike battery?

A: It is a Li-ion battery; the chemical is Li(NiCoMn)O 2.
Q: What is the difference between a Li-ion battery, Ni-Mn battery, and lead-acid battery?

A: E-bike Li-ion batteries have a longer cycle life; the normal cycle life is 800-1000 cycles, and also with light weight, small size, no memory effect, are non-toxic, and environmentally friendly.

Q: What's the temperature range of charge and discharge?
A: Charge Temperature: 0 to 45°C and Discharge Temperature: -20 to 65°C
Q: What kind of cells are used in this electric bicycle battery?
A: Different capacities with different cells; we make the battery with original A-grade brand and high-quality domestic cells, and all can be customized to your requests.

Q: Do your e-bike batteries come with a charger?
A: All of our e-bike batteries come with a charger. We have a normal charger and a fast charger. If you need a fast charger, please contact us.
Q: Do your electric bike batteries come with a BMS?
A: Yes, our batteries all come with a SEIKO IC BMS, with stable performance. This can protect the battery from short circuits, overcharging, overdischarging, and overcurrent.
