 Note:  a normal VSR can be used with LiFePO4; it may be useful to add a way to [[electrical:12v:alternator#disabling_alternator_charging|disable temporarily]] it to break the "stuckness". Also see [[electrical:12v:alternator#gotchas|the Gotchas section]] for related information.  Note:  a normal VSR can be used with LiFePO4; it may be useful to add a way to [[electrical:12v:alternator#disabling_alternator_charging|disable temporarily]] it to break the "stuckness".

 +The [[https://amzn.to/4m8mE6f|Cyrix-Li-ct]] is similar to the lead version with different setpoints:((https://www.victronenergy.com/upload/documents/Datasheet-Cyrix-Li-ion-120-A-EN.pdf))

 +===== the Orton method =====
  
 +Similar to the above, [[https://www.ortontransit.info/electrical|the Orton method]] uses a combiner to control power to an inverter.  The inverter in turn runs AC-DC battery chargers and other shore power loads.
