Features

Cold Weather Ready

Featuring our Low Temperature Series (LT) technology, the InSight 12V battery can safely charge at temperatures down to -20°C (-4°F).

Easy Installation

InSight batteries come in BCI group size GC2/GC8 allowing for easy installation without modifying trays or battery compartments.

Scalable System

InSight batteries offer freedom and flexibility by utilizing parallel connections, so you can scale your system to provide increased power and energy (up to 300Ah) as needed.

Intelligent Cooling

InSight Series® uses a carefully engineered cooling management system to quickly remove heat from inside the battery during conditions of high discharge and recharge currents. This prevents overheating of critical components and extends the life of the battery.

Super Smart BMS

The robust Battery Management System features a combined total of 48 charge and discharge MOFSETs that control current flow in and out of the battery, along with multilayer protective devices that prevent over/under voltage, current and temperature conditions. The multilayer protection allows InSight batteries to pass stringent UL safety standards.

Robust Communication

CANbus connections allow batteries to communicate real-time operating statistics like the voltage, current, state of charge and state of health, making InSight batteries more user friendly. Plus, all batteries feature a sleep and pulse recovery operation mode to conserve power.

Frequently Asked Questions

Can InSight batteries be connected in parallel or series?
RELiON’s InSight batteries were designed exclusively to run in parallel. Because they are in parallel, if any one battery goes offline, you will not notice any difference in performance, only duration. A parallel connection extends the reliability of each individual Insight battery to the entire array, giving you more power, more capacity, and less to worry about.
How does the heating element work?
The battery management system monitors the internal temperature of the battery. If the temperature drops below 32°F (0°C) and a charge cycle is initiated, the BMS will divert charge current to the heating element until the uniform internal temperature of the battery is safe for charging. The specific safe charging temperature differs. For small batteries it's 50°F (10°C), for larger batteries it's 41°F (5°C). See individual data sheets for details.
How long does the heating element take to warm the battery to a safe temperature?
Depending on how cold it is and which model of battery, the BMS will divert 5-15 amps of charge current to the heating element. The heating rate for the InSight 12V battery is 5⁰C per hour.
Does the heating element keep the battery warm during discharging also?
No, during discharge the heating element remains off. The battery will function according to the discharge voltage characteristics at various temperatures chart. It is perfectly safe to discharge in temps down to -4°F (-20°C).
How many amps does the heating element draw?
Depending on battery model, the BMS diverts 5-15 amps to power the heating element.
How can I determine the state of charge (SOC) of my InSight battery?
We recommend using a shunt-based fuel gauge to measure SOC with the InSight Battery. This type of fuel gauge accurately measures the discharge/recharge currents and calculates the Ampere-hours (Ah) flowing in and out of the battery. The LEDs on the battery will also indicate the SOC: 95% - 100% Solid Green Solid Green 75% - 95% Solid Green Flashing Green (every ½ sec.) 50% - 75% Solid Green Solid Yellow 30% - 50% Solid Green Flashing Yellow (every ½ sec.) 10% - 30% Solid Green Solid Red 0 - 10% Solid Green Flashing Red (every ½ sec.)
How do I charge InSight batteries?
It is best to use/select a Lithium, AGM or GEL charge profile in that order of availability. Consult your manual or charger manufacturer for directions on this capability. Spot check the battery SOC LED indicators with a quick press and release of the battery Power Button. Chargers typically display a solid Green Light when the charge is completed, and a flashing green light when the battery is near the end of charge (will vary by charger). Both conditions may or may not occur depending on your charger design. Neither condition is necessarily required to properly achieve a full recharge.
Is there a way to turn the batteries on and off without accessing the battery compartment?
The InSight Series Remote Button gives you the convenience to power on and off your InSight Series batteries without having to access the battery compartment. This high-quality plug-and-play accessory saves you time and energy.
