Protection Circuit Module for 7.2V Li-ion Battery Pack with 8A discharging limit
All Li-Ion Battery packs must connect to a protection circuit module to protect Li-Ion Battery from over charge, over discharge and prevent accidental battery explosion due to its extra high energy density. This protection circuit is specially designed for 7.2 V Li-Ion Battery pack made of one Li-ion cells. It also can be use for Polymer Li-Ion battery sold by Batteryspace.
Please connect battery pack with the circuit as the following drawing with wire provided.
Please be advised that this circuit will provide the following protections:
* Keep 7.2V Li-Ion Batery pack from overcharge
* Keep 7.2V Li-Ion Battery pack from overdischarge
* Keep 7.2V Li-Ion Battery pack 's discharging current lower than 8A.
Note: Batteryspace is not responsible for any damage cause by misunderstanding and misuse! Please read the following instruction carefully before assembling it to battery pack.

The BatterySpace Li-Poly Protection circuit PCS-S2A8 works excellent for all DIY and homemade Lithium Polymer batteries sold on Batteryspace and other brand Li-poly batteries. This PCB enables the user to easily attach two cells which equal up to 7.4 volts together (3.7v + 3.7v) and charge them safely. This product is quality because it doesn't overflow the batteries with too much current or voltage and keeps the user safe because using protection circuits properly will prevent explosions. It also prevents too much discharge from happening during use which saves the electronics that the power is being sent to. It has very simple instructions too. I find that with this Protection PCB Instructions I knew which parts to connect without much electronics knowledge. It only requires basic skills like soldering. The circuit is very space saving because of its small size. My purchase experience with Batteryspace was most pleasurable because they have very fair prices and the products are extremely durable. They have an enormous selection, which is great for making many different kinds of projects. I would most definitely purchase from them again because the shipping was very timely.
