   * a $25 constant duty solenoid would get the bank up  to Valt, at which point 70% of the current needed to charge Pb and 100% of the current needed to fully charge Li has already been  provided.  Solar would have to lug voltage up 13.8v -> 14.4v for Absorption/balancing.   * a $25 constant duty solenoid would get the bank up  to Valt, at which point 70% of the current needed to charge Pb and 100% of the current needed to fully charge Li has already been  provided.  Solar would have to lug voltage up 13.8v -> 14.4v for Absorption/balancing.
