Although the BattSix product line includes some sophisticated electronic systems, packVolts provides the minimum requirement to know how your battery pack is performing at a very affordable price.
A variety of low cost battery gages are available but packVolts includes features not found on the other gages...
Wiring an 'off the shelf' battery gage to your pack can be extremely dangerous, if the wire insolation becomes frayed it's possible to result in a fire. the only way to prevent this is to fuse the wires where they attach to the pack.
packVolts comes pre-wired with a double-fused battery harness.
Digital gages don't provide a way to turn the display on/off with the ignition key while maintaining isolated grounds between the 12 volt accessory voltage and the pack.
packVolts includes electronics to maintain complete isolation between the two.
Low cost digital gages are not perfectly linear and are normally calibrated at the factory for maximum voltage.
packVolts is individually calibrated for the voltage range of your pack.
