What Exactly Is Purpose Of TorkLift PowerArmor Solar Battery Box TLA7700LS?

Question:

That solar panel is pretty useless for keeping large capacity batteries charged in a boondocking situation where the main charge will come from the roof solar array Why dont you come up with something similar where the small solar panel charges something to keep the batteries heated when temperature s, that would be a seller ... this is way too expensive for something that doesnt provide any value ie the low charging small panel

The TorkLift # TLA7700LS was designed to keep a fully charged battery charged while in storage, and is not designed to recharge a battery that's been used.

This box is not for everyone, but if you do not have access to power where the trailer is being stored this is a much better option cost wise than replacing the batteries every year due to letting them drain down too far.
