Lithium BMS Sleep Mode & Recovery Feature:
KickAss Lithium Batteries are built with a Battery Management System (BMS) inside to
protect the battery from overcharging, over discharging and extreme temperature
changes.
One of the key functions of the BMS is to protect your battery by internally
disconnecting the load¹ when State of Charge drops below specific parameters, this will
then result in the battery entering into a “sleep” mode.
¹ (Load includes any accessories and/or device/s drawing charge from the battery. Eg:
fridges, pumps, food sealers, inverters, etc).
The KickAss DCDC MPPT Solar Battery Charger has a lithium battery recovery
function. This function has been designed to recover lithium batteries from a sleep
mode.
Lithium Battery Sleep Mode Indication:
When the lithium battery has entered sleep mode, the charger will show fault codes of
output open circuit, until all loads¹ are disconnected and a sufficient charge source is
connected.
How to Wake a Lithium Battery to Begin Recovery Mode:
First disconnect any load connected to the lithium battery.
Secondly, connect Alternator Input or Solar Input² to the KickAss DCDC MPPT Solar
Battery Charger.
The Charger will have all battery types (GEL, AGM, WET CALCIUM, LITHIUM) flashing
and the BULK and PULSE LED lights will remain on for 30 seconds (Indicated in
diagram above,) before entering Recovery Mode.
²(Alternator and Solar inputs must be above cut-in voltage for DCDC Charger)
