Frequently Asked Questions (FAQs)

Below you will find answers to frequently asked questions about Inventus Power PROformance batteries.


What’s the difference between lead acid vs lithium-ion batteries?

Lithium-ion batteries are a relatively newer technology that offer intelligence, communication, higher energy density and longer life, while eliminating the need for service and maintenance like watering and following complicated charging processes. Lead acid batteries can be used in a wide variety of applications outside of their optimal conditions, which will severely shorten their life, while lithium-ion batteries should be optimized through proper system integration for increased performance.

How do I select the right battery for my application?

The proper battery should match the system voltage, motor power, and duty-cycle requirements. If you are unsure, contact your dealer or our technical support team for assistance.

What is a BMS and why do I need it?

A BMS (battery management system) is the brain of the battery and an integral component of all Inventus Power batteries. It helps protect the battery from operating outside of safe conditions, communicates / collects data, and optimizes battery performance.

What is the difference between series and parallel connections?

Series connections are connecting the positive terminal of one battery to the negative terminal of another battery to increase voltage. Parallel connections are connecting positive to positive and negative to negative of multiple batteries to increase capacity, runtime and current. Please check the battery user manual to ensure proper wiring as not all batteries can be connected in series and/or parallel.

What is the difference between the PROformance M-series vs. S-series?

The M-series batteries are intelligent batteries with controllable logic pins to operate the terminals. The S-series has all the intelligence of an M-series battery but does not require logic pins to operate the terminals and the terminals will always be on.

What is the life expectancy of a lithium battery?

Our batteries were designed to last more than 2,000 charge cycles depending on the model, and may last as long as the system. The average cycle life of a lithium battery is 3-5x more than a lead acid battery.

What is a BDI (Battery Discharge Indicator)?

A BDI, also known as a battery guage, is a device that shows the battery’s state of charge (SoC).

Do I need a BDI to use with your battery?

Our batteries have LED indicators to provide battery SoC (state of charge) and diagnostics, so a BDI is not necessary. If a BDI is desired, we recommend using the Inventus Power Smart Battery Monitor (SBM-01) or connecting the system monitor via CAN. A lead acid BDI will not be compatible with lithium-ion batteries due to the voltage differences.

What is SoC?

SoC (state of charge) is the battery’s level of charge (energy remaining) expressed from 0 – 100%.

What does SoH mean?

All batteries will lose capacity as they are cycled or as they age. SoH (state of health) is the battery’s capacity compared to the initial capacity of the battery. Inventus Power’s PROformance batteries communicate battery SoH as part of the predictive maintenance features.

What does DoD mean?

DoD (depth of discharge) is the amount energy allowed to discharge relative to the overall energy in the battery.


What happens if my batteries are exposed to water?

Our batteries were designed for the elements and can be cleaned with high-pressure water. To go a step further, our PROTRXion batteries can be submerged up to 1 meter of water for 30 minutes.

What happens if I reverse the polarity?

We strongly recommend checking wires and connections to prevent reverse polarity on all battery installations. However, should the poloary be reversed on a PROformance battery, there are safety measurements to ensure safety.

Do Inventus Power batteries have a BMS?

Yes, all Inventus Power lithium-ion batteries include a BMS as it is an integral part of the battery to ensure performance and safety.

How does Inventus Power ensure its batteries are safe?

There are many battery suppliers in the market who do not have agency certifications on their batteries. These suppliers may only have safety certifications from the cell manufacturers, which is a component of the battery system. Inventus Power goes above and beyond by 1) testing and certifying our batteries against recognized global standards like UL and TUV for on/off-road applications and 2) complying with functional safety requirements to ensure potential issues are monitored, detected, and mitigated before they happen. Furthermore, we own 100% of the design and manufacturing process to ensure consistency and reliability.

Why is agency certification important?

Similar to UL certification for all of the household electronics, it is equally important for larger batteries to have the proper agency certifications to ensure safety.

Are lithium-ion (Li-ion) batteries safe?

Yes, lithium-ion batteries are very safe when properly designed, manufactured, and when used as intended.
