Can this battery be directly connected to a 100W x 18V solar panel, or must a separate charge controller be used?

The manufacturer's answer of "yes" has only been helpful to 5 out of 11 people. Weird. To help clarify, multi-cell lithium batteries should have an internal battery management system (BMS) that will cut-off any charge voltage outside the range. My LiFePO4 battery cuts off at 27.2V by the BMS settings, but my head-system floats around 28V to top the paralleled SLA bank I use for range protection. Note: Do not mix battery types without (qualified) engineering knowledge and adequate safety measures.

Description says "PCM." The seller says "BMS" in the answer. Obviously, these two are not the same. If it's "BMS," why hasn't seller contacted Amazon to change the description?

Can this battery be connected in series with other same batteries to make 24 or 36 volts?

You can connect them to 24v,and you should keep voltage of 2 batteries on same levels. It’s not good to connect them over 36v.

can you maintain the charge on this battery with a 5w solar charger?

Yes,we suggest 18v solar panel,and 5w seems little lower
