Recently purchased a 36 volt lithium and 2 -12 volt wet cell 3 bank charger from Astro First off when i call after hours a gentleman took my call and answered all my questions. My charger was shipped right away!! The thing is VERY heavy duty!! Wired it up inside my boat's console. So far so good!!!
I received the charger sooner than expected, which is unusual these days. So far charger is working as expected. The construction is robust and I expect to have many years of service.
