Product Description

CellShield is a low voltage cutoff device which provides cell-by-cell protection for lithium battery packs. By monitoring each cell individually, CellShield prevents individual cell overdischarge due to pack imbalance or cell variations.

CellShield provides a soft cutoff when the lowest voltage cell of the pack reaches the set minimum voltage. The minimum voltage is adjustable from 2.5v/cell to 3.5v/cell. This lets you set the proper cutoff voltage for your specific pack. For example, 8-10C cells typically use a 3.0v/cell cutoff, while 20C cells work better with a 3.2v/cell cutoff. CellShield’s cutoff voltage is set with an easy-to-use potentiometer. There are no programmers to buy or complicated programming procedures. With CellShield, you turn the arrow to the cutoff voltage you want and go fly.

CellShield also features optional thermal probes, which prevent pack damage due to overheating. When using the thermal probe, if the battery temperature rises above 150 degrees, CellShield will reduce the throttle command sent to the ESC in an attempt to bring the battery temperature back down. If the battery stays above 150 degrees, CellShield will enter soft cutoff mode. When using the thermal probe, CellShield alerts the user to temperature faults by flashing the red Temp light. The thermal probes are extremely thin, and can often be inserted between the innermost cells of the pack, where pack temperature is highest.

CellShield installs easily between your receiver and ESC. Simply plug the battery port on the CellShield into the tap connection on your battery, and it will automatically detect the number and cell order for any pack with .1” tap spacing. If you are running a battery with 2mm tap spacing like Thunderpower, a 2mm to .1” adapter is all that is required to use CellShield. Suitable Thunderpower adapters can be found here. CellShield will then light an LED corresponding to the detected cell.  You can even plug the battery tap in “backwards” and in any position, and CellShield will operate correctly. No soldering is required to install CellShield.

CellShield works with any ESC and power system except some opto-isolated ESCs when used with receiver batteries. For cell-shield to operate, the battery ground and radio ground must be at the same level. This is the case for all ESCs with a built in BEC (whether or not the ESC’s BEC is being used) and all ESCs using external BECs.

For a solution that works with a wider voltage range, check out LipoShield.

CellShield is intended for aircraft with 0-100% style one direction only throttle. A future product will be aimed at cars.
