Full Safety Protections Built-in multiple protections including over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, reverse polarity, and over-temperature, waterproof and spark-proof, the battery is fully protected. [Adjustable Pole Mount Bracket]The pole mount brackets allows you to easily adjust solar panel angle among 0-15-30-45-60 degree according to personal requirements. The mount brackets were designed for pole diameter 1.5 - 3.0 inch/40-80MM. Wide CompatibilityIt's not just a solar battery trickle charger, it's an advanced solar battery charger maintainer. A fully-automatic, worry-free smart solar battery charger for 12-volt sealed lead-acid car, automotive, marine, RV, powersport, boat, dump trailer, gate opener, fence and deep-cycle batteries, including flooded, gel, AGM, SLA and maintenance-free, plus lifepo4 lithium batteries.

- Smart MPPT Technology This 12v solar panel battery charger is crafted with SUNER POWER's unique Smart MPPT technology, so all of its core parts, including its mppt charge controller and solar panel are built using premium and durable materials. The innovative MPPT-Charge-Controller-Technology allows to deliver high tracking efficiency of up to 99% and peak conversion efficiency of 98%, improve approximately 20%-30% utilization rate than other competitors.
- Improved 3-stages ChargingThe improved 3-Stages charging algorithm (Bulk, Absorption, Float) allows to charge 12-volt battery more effectively, ensures battery is safely recharged and increases battery life and performance. The charging will be cut off when battery is fully charged, and automatically resumed when battery is not full, totally free maintenace.
