Lithium Battery Activation

The Wanderer PWM charge controller has a reactivation feature to awaken a sleeping

lithium battery. The protection circuit of lithium battery will typically turn the battery off and

make it unusable if over-discharged. This can happen when storing a lithium battery pack in

a discharged state for any length of time as self-discharge would gradually deplete the

remaining charge. Without the wake-up feature to reactivate and recharge batteries, these

batteries would become unserviceable and the packs would be discarded. The Wanderer

will apply a small charge current to activate the protection circuit and if a correct cell voltage

can be reached, it starts a normal charge.

Remote Temperature Sensor (TS-R):

The Wanderer is shipped with by itself with no additional components. Optional components

that require a separate purchase:

Measures the temperature at the battery and uses this data for very

accurate temperature compensation. The sensor is supplied with a 6.6ft

cable length that connects to the charge controller.

BT-1 Bluetooth Module:

The BT-1 Bluetooth module is a great addition to any Renogy

charge controllers with a RS232 port and is used to pair charge

controllers with the Renogy BT App. After pairing is done you can

monitor your system and change parameters directly from you cell

phone or tablet. No more wondering how your system is

performing, now you can see performance in real time without the

need of checking on the controller’s LCD.
