Alternator & Starter Battery Charging
RV Alternator Charging Kits (Lithium Batteries)
DC/DC Charging options
DC/DC chargers give three-stage charging, current regulation, and are capable of bringing batteries up to 100% State of Charge
Battery combiner options
Battery Combiners deliver higher current up to about 80% State of Charge and aren’t recommended for alternators rated less than 160A, battery banks that can’t handle 160A, or vehicles with warranties that stipulate a lower charge rate.
Enable DC/DC charging from your alternator to a secondary Lithium, AGM or Flooded battery bank. This kit is ideal for van conversions and skoolies with older alternators or lithium batteries with input current limits under 100A.
Ideal for: Vans, skoolies, motorhomes
*Please note that cables length needs may vary by application. Please email info@amsolar.com if you would like to customize the cable lengths to better suit your needs.

Enable 120A alternator charging of a secondary AGM or Flooded battery bank. A boost button lets your house batteries start your ignition when your starter battery is dead. This kit is ideal for van conversions and skoolies. Not for use on rigs with an ECU.
Enable 230A alternator charging of a secondary AGM or Flooded battery bank. A boost button lets your house batteries start your ignition when your starter battery is dead. This kit is ideal for van conversions and skoolies.
Enable 120A alternator charging of a lead-acid battery bank from a tow vehicle via the 7-pin connector. This kit is ideal for horse trailers, cargo trailers, or anything connected to a tow vehicle with a 7-pin connector and not originally configured for house battery alternator charging.
Misc. Alternator/Starter Charging Kits
Designed for a Ford Transit with a 175A CCP (Consumer Connection Port) #2 that is only active when the ignition is on. This kit will allow a straight shot passthrough from your alternator to a house battery system. This kit comes with 25’ of 2/0 cable and a 200A breaker for over-current protection.
Designed for alternator charging kits that utilize an Orion or other form of DC/DC charging. This kit will allow a momentary emergency boost feature if one is in need of jump-starting their chassis battery. This kit comes with 32’ of 2/0 cable, a 200A EV200 Relay, a 200A Breaker for over-current protection, and a momentary switch for activation. Note: It is important to note that a chassis start-up can consume more current than can be safely discharged from a small lithium battery bank. It is best to use this system by pressing the momentary switch for 30 seconds, releasing it, then turning the ignition.
Misc. Alternator/Starter Charging Components
Victron Cyrix battery combiners connect your house battery bank to your starter battery and alternator to allow alternator charging. Additionally, when a charge is applied to a house battery bank the Cyrix will close and allow current to flow to the starter battery. Select an appropriate Cyrix based on your house battery type and alternator current rating.
Alternator 160A or less - 120A Cyrix
Alternator more than 160A - 230A Cyrix
This device is ideal for lithium alternator charger system upgrades in motorhomes where a smart alternator is used, or when the lithium battery bank cannot handle high current.
The Magnum SBC is an innovative, 25 amp two-bank battery combiner. It is designed to monitor and charge a second battery using a portion of the current that is charging the primary battery.
