A bank of gel cells isn't so tolerant of such high voltages, and require to ensure your controller keeps the voltage at a smaller range Power wire versus the lead acid batteries are equipped for. It is a choice to conserve a limit of approximately 14.2 volts with gel cells. An occasional small overcharge may not hurt, but better safe than apologies. Gel cells are more costly than most lead acid batteries or any serious overcharge will shorten their life expectancy quickly.
Don't assume just any memory will work, on the. Different versions of the G5 utilize different ram chips, and / or chips that meet the published specifications have been known to cause problems.
