China High Energy Density 36V Lithium Ion Battery Manufacturer

For electric bicycles, scooters, power tools and garden tools, 36V is an ideal voltage that balances runtime and portability. Vcell Power 36V Lithium Ion Battery delivers high energy density solutions from a professional Chinese manufacturer. Backed by our team’s decades of lithium battery expertise, our products are widely adopted as replacements for lead-acid and LiFePO4 batteries, storing more energy at the same size and weight. Our batteries have been exported to over 80 countries and won worldwide recognition. Below are detailed introductions based on common questions.

What is a 36V lithium ion battery? How many cells does it contain?

A 36V Lithium Ion Battery is assembled with 10 pieces of 3.7V lithium cells connected in series. Its nominal voltage is 36V, full charge voltage reaches 42V, and discharge cut-off voltage is around 30V.

Vcell Power assembles complete battery packs with standard cells, built-in BMS and structural parts via mature production processes. We own comprehensive capabilities from product design to mass production, supported by rich experience in lithium battery manufacturing.

Advantages of 36V Voltage Platform

Why is 36V lithium battery better than LiFePO4 and lead-acid battery?

Vcell Power 36V Lithium Ion Battery has obvious advantages over traditional batteries:

·         Higher energy density: It stores more energy within the same size and weight for longer running time.

·         Lighter & more compact: It features smaller volume and lighter weight under the same runtime requirement, bringing better using experience.

·         Better low-temperature performance: It maintains good capacity and discharge performance at low temperatures for stable operation in cold environments.

We provide multiple capacity options for 36V lithium batteries. Mass production also brings competitive pricing and stable supply.

How to choose the right capacity for your 36V battery?

Capacity is the key factor for selecting 36V Lithium Ion Battery. Please follow the steps below:

Step 1: Calculate required energy

Device Power (W) × Working Hours = Total Energy (Wh) Total Energy ÷ 36V = Required Capacity (Ah)

Step 2: Select by application

Step 3: Check dimension compatibility

We support customized housings and connectors. You can send us the battery compartment drawing for a tailored mounting solution.

Our mainstream 36V 30Ah Replacement Lithium Ion Battery Pack is designed for long runtime and heavy-load use. Equipped with built-in BMS, it provides full protection and reliable cycle performance.

How important is the BMS protection for 36V batteries?

All multi-cell 36V Lithium Ion Battery packs are equipped with professional BMS (Battery Management System). Our built-in BMS ensures safe operation in the following aspects:

·         Overcharge protection: Cut off charging circuit to prevent cell damage.

·         Overdischarge protection: Stop discharge to avoid permanent capacity loss.

·         Overcurrent protection: Cut off output when abnormal current occurs to protect cells and circuits.

·         Short circuit protection: Quickly disconnect the loop once short circuit is detected to avoid safety hazards.

We also offer BMS with SMBus or CAN communication upon request for devices with power display functions.

What devices are suitable for 36V 8800mAh and 36V 30Ah batteries?

We launch 36V 8800mAh 18650 Lithium Ion Rechargeable Battery

 for multiple scenarios. It is widely used for long-distance electric vehicles, AGVs and heavy equipment.

·         For daily commuting and light electric vehicles: Choose medium-capacity 36V batteries for light weight and cost-effectiveness.

·         For long travel, delivery work and lead-acid replacement: Choose 36V 30Ah high-capacity packs to reduce charging frequency.

Our replacement battery packs help customers stabilize supply chains and improve product competitiveness.

Frequently Asked Questions

Q: Will it cause problems if a fully charged 36V lithium battery is left unused?

 A: No. The built-in BMS prevents overcharge. To slow down aging, please discharge the battery to 40%-60% state of charge and store it in a cool and dry place if it will not be used for over one month.

Q: Can 36V 30Ah lithium battery directly replace lead-acid battery?

A: Yes, if the voltage matches. Our lithium battery is lighter and has higher energy density. Please note that a dedicated lithium battery charger is required; original lead-acid charger cannot be used.

Q: Do you support customized connectors for 36V batteries?

A: Yes. We customize housings, connectors and wires according to your drawings. Provide your requirements on voltage, capacity, size and working current, and our team will make matching solutions.

Q: Which regions do your products export to?

A: Our 36V Lithium Ion Battery are delivered to over 80 countries including Europe, America, South Africa and Australia. We provide complete shipping documents such as UN38.3 and MSDS for international logistics.
