1.Does it come with Anderson cable? What is the size of the Anderson connector?

Rego batteries doesn't come with an Anderson cable. And the connector is Gray Anderson 350 connector (with dust cover).

2.How can I activate or put the battery into shelf mode?

The battery is shipped in shelf mode. The battery can be activated by pressing and holding the battery button for 1 second, and the battery can be put into shelf mode by pressing and holding the battery button for 3 seconds.

3.How long will the battery last?

Our battery is capable of 6000 cycles of perfect charge and discharge. If you live a completely off-grid life, calculated at the rate of a full charge and discharge per day, you will be able to use it for more than 10 years.

4.Can you recommend a solar charge controller for this battery?

When purchasing a solar charge controller, you must confirm that the controller is compatible with the lithium-iron phosphate battery. The Renogy Adventurer, Rover, Wanderer, and Rego charge controllers are all fully compatible with our lithium-iron phosphate batteries. We recommend that you use the Rego controller for a perfect fit of communication and wiring.

5.Can this battery be combined with a 12V lead acid battery bank?

No, you can't. All the batteries you connect together should be the same capacity (Ah), the same voltage (V), and most importantly, the same battery type (LFP). And it would be better if they come from the same brand.

6.Can I connect multiple batteries in series to build a 24V, 36V, or 48V system?

No, you can't. These Renogy lithium batteries do NOT support connecting in series. They are made ONLY for connecting in parallel using identical batteries with the same type (lithium), same capacity (Ah), same voltage (V), and same brand (Renogy).

7.Can I leave this battery in cold weather? I live in my van and this battery will be in the cold. I was wondering if the cold will affect it.

This Rego battery has a self-heating function. The operating temperature for discharging is -4°F to 140°F / -20°C to 60°C. The operating temperature range for charging is -4°F to 122°F / -20°C to 50°C.

8.How many batteries can I connect at most?

We recommend a maximum of 8 batteries in parallel.

9.What kind of communication does this battery support? Bluetooth or CAN communication?

The Rego battery has built-in Bluetooth and also has CAN communication ports. It supports both Bluetooth communication and CAN (RV-C) communication.

10.When does the battery's self-heating function work？

The battery has a built-in heater. When the battery temperature drops below 41°F (5°C), and the charge current is stable and greater than 15A, the heater starts operating automatically, and the Heater Status Indicator lights up green.
