Battery Health Preservation
The BatteryPlus35-II preserves battery health by preventing the battery from
excessive discharge. The BatteryPlus35-II will start a two-stage shutdown or Low
Voltage Disconnect (LVD), powering down the BatteryPlus35-II outputs. This is to
conserve remaining battery capacity until the battery can be charged.
Table 7: LVD Mode voltage thresholds
LVD MODE LEAD ACID LIFEPO4 (HA ONLY)
ECO 10.5V 12.0V
Storage
9.8V 11.5V
Recovery
12.8V
13.8V
The BatteryPlus35-II will enter the two stages of LVD, ECO Mode and Storage Mode,
when the caravan’s battery voltage falls below the LVD thresholds.
Note +BRK Battery Output (40A rated) is not controlled by the LVD mode.
ECO MODE
The BatteryPlus35-II will provide power to your battery monitor. However, power to
the load terminal block will be turned off (except for terminal 1)
To exit ECO Mode, start battery charging. The BatteryPlus35-II will exit ECO Mode
when the battery charges to the Recovery voltage. Upon exit of ECO Mode, the
BatteryPlus35-II will automatically return to its previous state of operation.
When in ECO Mode you may temporarily turn on caravan loads for a short time by
cycling the switch connected the BatteryPlus35-II’s RSW input or the battery button
on Trek2, Odyssey or Mobile Apps. This feature allows you to retract slide-outs or
electric steps.
STORAGE MODE
Power to all loads and the accessories including battery monitors and remote
controls will now be turned off
To exit Storage Mode, start battery charging. The BatteryPlus35-II will exit Storage
Mode when the battery charges to the Recovery voltage.
When in Storage Mode you may temporarily turn on caravan loads for a short time by
cycling the switch connected the BatteryPlus35-II’s RSW input.
