Other findings
- Battery type detection
- Detects the chemistry; two stages once it settles on lithium
- Lithium absorption voltage
- 13.6 V absorption, held until the power is cycled
- Lithium bank size caveat
- Over 200 Ah may need the power cycled to finish
- Lithium bulk duration
- Bulk runs one to four hours; the hour minimum is for balancing
- Lithium bulk voltage
- 14.6 V in bulk, in its lithium profile
“The two-stage “smart” charger continuously measures the battery voltage output and regulates the amount of charge using two modes of operation: Bulk and Absorption mode.”

“This is accomplished by reducing (from bulk mode) the output voltage to 13.6 VDC and remaining at this voltage until the power is cycled to the converter.”

“If your application requires longer than four hours (such as a larger battery bank > 200 Ahr), a simple cycling of power will reset the timers.”

“For a full battery, the bulk stage has a minimum time requirement of one hour, which allows the lithium cells inside the battery the time required to “balance”. For an empty battery, the bulk stage has a maximum time requirement of four hours.”

“This is accomplished by boosting the output voltage to 14.6 VDC and allowing the maximum current to flow as required by the loads.”
