Simple selection guide
Is this the right cell for your build?
Match the cell to the job, then confirm the manufacturer limits for the finished pack.Best match
Low-current electronics, lighting, backup systems, sensors, and gentle energy-storage duty.
A better alternative when
Choose a power or hybrid cell for tools, RC, UAV, high-watt mobility, or other demanding loads.
Application guide
Where this cell fits
Low-current runtime packs, energy storage, backup power
Moderate loads only after current and thermal validation
Power tools, RC / UAV, high-watt mobility, vape devices
Keep the finished pack within every manufacturer voltage, current, and temperature limit.
Engineering limits
Current limits
Manufacturer continuous-discharge ratings only. Pulse and over-current laboratory values stay on BatteryRealData.The displayed continuous limit comes from the matched manufacturer data sheet. Use design headroom and validate heat in the finished pack.

Current envelope
Relative current values from the matched manufacturer data sheet. Bar length is comparative, not a recommendation.
Current and runtime translation
Idealized constant-current runtime based on nominal capacity. Real packs deliver less because voltage sag, heat, cutoff voltage, and losses matter.

It assumes equal current sharing between matched cells. It does not account for heat, aging, imbalance, conductor resistance, duty cycle, enclosure airflow, or BMS limits.
Read before purchase and use
Safety warning for lithium-ion battery usage
Customers should understand lithium-ion battery handling and safety before purchase. Lithium-ion cells can cause fire, burns, venting, or explosion if misused, overcharged, shorted, crushed, punctured, overheated, or physically damaged.
Use only with a compatible lithium-ion charger, BMS, or protection circuit designed for the cell voltage, current, and temperature limits. Never leave batteries charging unattended. Charge and store on a fire-resistant surface away from combustible materials.
By purchasing and using lithium-ion cells, the user assumes responsibility for correct handling, storage, charging, pack design, and application suitability.
Important usage guidelines
- Not for use in e-cigarettes, vape devices, or similar devices.
- Always use in a protected battery pack or properly controlled test fixture.
- Do not exceed the data sheet maximum charge voltage.
- Do not discharge below the recommended system cutoff voltage.
- Do not charge or discharge outside the data sheet temperature limits.
- Do not carry loose cells in pockets, bags, or toolboxes where they can contact keys, coins, tools, or other metal objects.
- Store and ship cells in protective cases or insulated packaging.
- Do not use batteries with torn wrappers, missing insulator rings, dents, rust, odor, leakage, deformation, heat damage, or visible damage.
- Do not solder directly onto cell terminals. Use proper spot-welding methods only.
- Do not alter, dismantle, puncture, crush, burn, immerse in liquid, or expose cells to open flame.
- Keep away from children and pets.
Pass all safety information to end users to promote safe handling, correct pack design, and proper use.
Common questions
EVE 35V FAQ
Does this cell include built-in protection?
No. It is an unprotected industrial cell. A compatible device or finished pack must provide over-charge, over-discharge, over-current, short-circuit, and thermal protection as required by the application.
Is the maximum current the normal operating target?
No. A manufacturer maximum is a limit under stated conditions, not an automatic long-term design target. Use headroom and validate the finished pack under the actual load, duty cycle, cooling, and temperature limits.
Can I solder directly to the cell?
No. Direct soldering can overheat and damage the cell. Use correctly configured spot welding and suitable interconnect material.
Can I mix this cell with another model or an older batch?
Do not mix different models, ages, capacities, internal-resistance groups, batches, or states of charge in one pack. Build with matched cells and balanced parallel groups.
Can I carry or store the cell loose?
No. Isolate the terminals in a protective case or insulated packaging. Never carry loose cells with keys, coins, tools, or other conductive objects.
