1 x grey Anderson connector (In/Out)
1 x blue Anderson connector (DC In)
The BTLITH12110-SL-DCS model contains one (1) grey Anderson plug connector and one (1) blue Anderson plug connector, accessible from the side of the battery as shown in Figure 4. The grey connector can used as input and output for charging and running loads.
NOTE – There are no internal fuses inside the battery so an external fuse must be used for the grey Anderson connector, 100A maximum, to ensure never to exceed the BMS 100A continuous charge and discharge rating. The cable to the blue Anderson connector should be protected by an external fuse (at least 20A, rated for the cable size), as close as possible to the vehicle battery/alternator.
Charge sources to the grey Anderson connector could include:
- External AC charger; or
- External (regulated) solar charger.
The blue connector is reserved for a DC input, to make use of the internal DC-DC charger. The DC-DC charger is rated for 20A input from a vehicle alternator or start battery.
The internal 20A DC-DC charger contains a Voltage Sensing Relay (VSR). As shown in Figure 5 the VSR has an LED status light and adjustment trim pot, which can be used to adjust at what input voltage (from the vehicle alternator / start battery) the DC-DC charger turns on and off. There is a dead-band of 0.5V, so that it typically turns on at 13.3V and turns off at 12.8V.
