Can I connect with Soltronix panel to a lithium-ion battery?
Currently, all of our off-the-shelf solutions are designed to charge 12V lead acid systems. You can only use 6Ah or larger lithium-ion batteries designed as lead-acid replacements.
These batteries contain charging circuity designed to protect the battery. Charging many lithium-ion batteries will terminate at roughly 90%, but for some (K2 Energy) you can charge the battery completely.
