    • You must use a protection IC (PCB) to keep battery from overcharge and over discharge
    • Never solder directly onto the Li-ion battery as overheat might cause battery to explode. If you are making a pack or need to solder batteries together, you need to get battery with tabs on it. You will solder to tabs instead directly onto the battery.
    • Please read more safety warning about Li-ion battery
    • For DIY, you may add tabs as an option at a little extra cost
    • If you DIY by yourself, you MUST install Our PCB or your own PCB with the following feature:
      • 4.2V/cell over-charge protection
      • 2.5V/cell over-discharge protection
      • Max current over-drain protection
      • Short circuit protection.  
    • won't liable for any mis-use due to any other brand of PCB applied 
    • You must choose  Our smart Li-Ion battery charger to charge the Li-Ion cell or pack. Never use conventional DC charger to recharge the Li-Ion battery.
    • It is perfect for building battery packs for RC air, RC car, and RC robots  which requires compact size, less weight and higher energy
