I want to be able to connect a small solar panel to trailer batteries, while in storage for weeks/months on end, to keep the batteries ready to roll and always charged.

Can someone recommend a small solar unit that does not require a charge controller.....2 amp......5 amp....??
Brand names?.....

Batteries to be kept charged are 2 Trojan T-105.

On other batteries, I have used a 1 1/2 amp float charge battery maintainer but that required 110V outlets.
