Solar Back-Up power project

I was wondering about my PWM charger and found this paper..

It seems like I should have been 'periodically' putting a load on the system. Eat up some Ah at night, and let it charge up the next morning. That might keep the cells in tip-top shape. If I buy the same old lead-acid batts..

Looking at this 48v pack. https://bigbattery.com/products/48v-...on-power-pack/
It might be chargeable with the TS-45 if I turn off the PWM and tweak the charge & float voltages.
