can someone here email me a simple sketch for a 15 cell, 18 volt pack wired in series with the cells in 3 rows of 5? One end would be FREE+, other FREE-, with the others in series, with the first strap at number one MINUS and the last one at number two PLUS, again leaving one PLUS and one MINUS FREE to connect with the NECK tabs. Temp sensor not used as all protection is at the charger. No NECK battery either. All 15 cells in the pack.
