description

This 36V lithium ion battery pack has a 10S2P configuration with 5Ah (amp-hours) capacity and 40A (amps) maximum continuous discharge rating (adjustable).

18650 lithium-ion battery packs are constructed by spot-welding 18650 cylindrical cells in serial or parallel. The resultant battery has high energy density and cycle life with low cost compared to other power options. Cylindrical cell formats also show high reliability compared to other format options.

This 20 x 18650 battery pack uses a 10S2P Samsung 25R5 (INR18650-25R5) pack configuration. The resultant 10S2P li-ion pack has a 5000mAh 36V 18650 battery specification.

Please note that these specifications are assuming 3.6V per cell. Many manufacturers assume 3.7V per cell in order to inflate voltage and power ratings. This battery pack is equivalent to a 37.0V lithium ion battery pack.

The 10S2P battery pack specifications make it suitable for e-bikes, power tools, UAVs/drones, consumer electronics, and many other applications.

The battery uses high-quality Samsung 25R5 (INR18650-25R5) cylindrical cells imported from Korea, which have a medium gravimetric energy density rating and a high maximum continuous current discharge rating compared to other cells.

Assembly and testing is performed in our facility in Dongguan, China. PCM/BMS, connectors, tabbing, pack shape and other requests can be accommodated.

All Voltaplex packs typically start with a 6 to 12+ month free replacement warranty covering authenticity, performance, age, and defects. Due to the variability in battery pack specifications, applications, and custom parts, the warranty period may be determined on a per-product basis.

Section 3: Exposure

  1. Use extinguishing media suitable for materials that are burning. For example, a large amount of cold water, sand, vermiculite, or other dry powder, or CO2 may extinguish early-stage lithium-ion flames. Use metal fire extinction powder or dry sand only if a small number of cells are implicated.
  2. If you come in contact with fluid discharge, wash the affected area immediately with soap and water for at least 10 minutes and seek immediate medical attention to reduce the risk of serious personal injury.
  3. If fluid contacts eyes, flush with water for at least 10 minutes and seek immediate medical attention.
  4. If smoke or other inhalants or chemical smells are present leave the affected area immediately and seek medical attention.
  5. If any parts are ingested or accidentally swallowed, contact a poison control center immediately.

 

Section 4: Safety Circuits

  1. Battery packs should have safety protection circuitry installed to prevent safety incidents like fire or explosion, namely overcharge, over-discharge, and overcurrent safety functions.
  2. Bare packs without protective circuitry require extra precautions.

 

Section 5: Handling

  1. Do not disassemble prior to expressed permission.
  2. Do not bypass safety devices or equipment.
  3. Do not attempt to charge a physically damaged unit.

  3. Remove the battery pack from the charger once it is charged.
  4. Control storage environment especially temperature and moisture.
  5. For longer term storage, battery packs should be stored at 30%-50% of maximum charge condition.
  6. Improper storage may result in battery pack capacity and cycle life reduction as well as loss of function and possible safety hazards from a decomposing cell, for example from under-voltage conditions.
  7. Do not allow battery pack voltage to deplete further than the minimum pack under-voltage rating, or the minimum voltage (discharge cut-off or end voltage) per cell multiplied by series.
  8. Monitor the battery pack voltage in storage for abnormalities.
  9. Charge the battery pack at least once every two to six months.
  10. Self-discharge will drain energy and cause over-discharge conditions unless the battery pack is recharged. Over-discharge conditions may result in a loss of function or possible safety hazards.

 

Section 7: Battery Charging

  1. Use “constant voltage/constant current” to charge lithium-ion batteries.
  2. Verify the polarity of the batteries before charging so that they are never charged with the polarity reversed.
  3. Use only supplied chargers and charging procedures or approved charging equipment. Recharge the lithium-ion battery pack by plugging in only compatible and approved power adapters, power cords, and the like.
  4. Charge above zero degrees Celsius (recommended to charge above 3 degrees Celsius) unless otherwise specified.
  5. Charging should be done as soon as received from shipping, never over four days after received.
  6. Do not let battery pack become depleted. If depletion occurs, charge battery pack immediately.
