SMDC DC-DC Battery Charger With MPPT 30A
Product Introduction
SMDC 30A/60A DC-to-Dc MPPT On-Board Battery Charger can charge a service battery in two different ways, The muiti-stage charger can utilize connected solar panels or an alternator linked to a starting battery. While your vehicle's alternator prioritizes your starting battery, this unit will allow your solar system to charge your service battery first! it's the smart way to keep yourself fully charged and off-grid longer! with multi-stage charging and multi-chemistry functionality, DC-to-DC MPPT charger covered Flooded, Gel, AGM, and Lithium batteries.
Product features
1. Multi-chemistry battery types ( flooded, gel, AGM, and lithium)
2. 3-stage charging (bulk, absorption , and float)
3. Smart protection features ( battery lsolation, over-voltage safety, overheat protection, and short circuit protection)
4. Overcomes voltage drop caused by long cable runs
5. Able to charge an auxiliary battery to 100% state of charge
6. Increases run time of loads, such as fridges and lights
7. Prolongs batter y life
