 Cautions

 

  • Li-Ion Batteries may explode if charged or discharged improperly.
  • You must possess knowledge of electronic and understand how to handle Li-ion battery. 
  • We reserve the right not to sell and void the warranty it you don't meet the above statement.
  • You must use a protection IC (PCB) to keep battery from being overcharged and over-discharged
  • Never solder directly onto the Li-ion battery as overheat might cause the battery to explode. If you are making a pack or need to solder batteries together, you need to get the battery with tabs on it. You will solder to tabs instead directly onto the battery.
Standard Charge Diagram
with MTI 8 Channel Battery Analyzer
Article  In general, the total mAh g−1 capacity of Li-ion cells may be expressed in terms of anode and  cathode capacity as follows:
Total cell (mAh g-1) =  (CA*CC*QM) /(CA*QM  + CC*QM + CA*CC)
 Optional
  • For DIY, you may add tabs as an option at a little extra cost
  • You may choose our smart charger to charge single 18650 cells
    • 4.2V/cell overcharge protection
    • 2.5V/cell over-discharge protection
    • Max current over-drain protection
    • Short circuit protection.
