Polymer Li-ion Battery Module: 18.5v 20Ah ( 370 Wh) - 14 A Discharging rate (30.0)

• 18.5 V 20 Ah pack is made by 10 pcs Polymer Li-Ion Battery: 3.7V 10000 mAh (9059156) , 10A rate with two PCM.
• Wrapped by heavy-duty Heat shrink tube
• Optional for 1 pcA Fire Retardant Bag: 295mmx230mmx75mm --- Reduce the chance of damage if caught fire
  • This Fire Retardant Bag (Li-Ion Safer Bag) is intended to reduce the chance of damage in the event of catching fire.
  • Must locate & seal the battery pack in the bag  while charging / leaving without any attention 

 Voltage                           

• Two PCM with Equilibrium Function(10A) installed with the  battery pack and protects the battery from
  • Overcharge       (> 21 V)
  • Over-discharge  ( <12.5V)
  • Over drain ( >20 Amp)
  • Short circuits
  • Must wait min of 30 minutes after battery is fully charged to allow the pcm to perform balance function on all the cells within the pack.
• Two 7.0 Amp polyswitches are installed to limit  max. discharging current and to protect wrong polarity

• Two charging terminals: 6" wire of 21 AWG with Universal two pin female plug. which connect to each 18.5V 10Ah module
• Two discharging terminals: 6" wire of 16 WAG wire with standard male Tamiya connector, which connect to each 18.5V 10 Ah moduleseparately 
• Excluded one Connector Adaptor :2 to 1  Parallel Connector( 2 Standard Female in parallel to 1 Standard Anderson ) for connecting two modules in parallel and.  Warning:  Must unplug discharging connector adptor ( 2 to1 ) before charging. Otherwise battery may lose balance 

• You shall use two 1.5A Smart Li-Ion battery charger to recharge battery pack from charging terminals.  In this way, we can get better power balance.
  • The estimated charging time is 10 hours
  • The pack must be plugged by the universal two pin male plug of the charger with correct polarity
    • Positive (Large universal two pin male plug) to Positive  (Large universal two pin female plug)
    • Negative (Small universal two pin male plug) to Negative (Small universal two pin female plug
• You can connect 18.5V Polymer Li-Ion battery to Smart DC-DC converter , and regulate output voltage to 3.3V, 5V and 12V

• Autonomous submarine to drive a 12V DC motor
• RC robot and RC aircraft with higher energy needs
• Building external battery packs for Laptop computers with DC input 19-21V. Gives laptops an extra 16 hours of running time!!! 

• Please note this battery is for R&D use only and NOT for individual customers. We are not responsible for any damages or losses caused by misusing (included but not limited to: impropercharging / discharging, any changes of this battery pack,misassembling batterypacks)
• Never discharge the battery pack beyond Max. limit.(14Amp Max)
