Tweaking soneil 36v charger for lifepo4

This charger, soneil 3650 S, can be adjusted to a higher voltage to charge lifepo4 easily. Easy as pie if I did it. One this charger one pot has an adjusting screw on the top, located near the edge of the board near the charge indicator led. A tiny twist on the screw and a check with a voltmeter and I have a 47v charger instead of the 44.5 v sla setting. Apparently other soneils can also do this, but this one is easy since it only has one adjustable pot to look for.
