  • Li-Ion Batteries may explode if charged or discharged improperly.
  • You must possess knowledge of electronic and understand hot 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 overcharged and over-discharged
  • 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.

  • To reach max capacity of 2800mAh, you MUST charge the battery to 4.30V. PCB with 4.30V cut-off must be applied.
  • For DIY, you may add tabs as an option at a little extra cost
  • You may need to buy Li-Ion 18650 cell series Battery Holders with PCB installed. Please click here to order separately
  • If you DIY by yourself, you MUST install Our PCB or your own PCB with the following feature:
    •  4.3V/cell over-charge protection
    • 2.5V/cell over-discharge protection
    • Max current over-drain protection
    • Short circuit protection.  
    • Batteryspace.com won't liable for any mis-use due to any other brand of PCB applied 
    • If you don't know how to make Li-Ion pack, please don't DIY, click here to choose a pre-wired Li-Ion pack module from 3.7V-37V
