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.
For DIY, you may add tabs as an option at a little extra cost
You may need to buy Li-Ion 10440 cell series Battery Holders with PCB installed.
You may choose our smart charger to charge single 10440 cells
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
Each cells with high capacity of the limited size.
Cells to make up a pack .There is good quality match between the cells.which is achieved through strict control technics procedure.
