No. See also the comments about BATTERY CHARGE in 'man 8 blazer' (the successor of the megatec and megatec_usb drivers) that is in the trunk. > And, if not, how can I determine the low limit?

Don't bother, use 85% of the nominal battery voltage and you'll probably be fine. So for a 12V (nominal) battery system, this would be 10.2V. The charge calculation is only there, because people expect the driver to report it. You shouldn't make decisions based on this (unreliable) value. See above.

These are based on a common protocol core and separate communication modules for RS-232 and USB respectively. This is much cleaner than wrapping a USB layer around an existing RS-232 driver. Make sure you read the man page before upgrading, since there are some incompatible changes. For instance, it will by default *not* report battery.charge, unless you tell it the levels for battery.voltage.low and battery.voltage.high. This in order to avoid the confusion with battery.charge never reaching 100% if the levels are set automatically (which was a bad idea from the start).
