Do Invicta batteries have an integrated BMS?
All Invicta batteries have an integrated BMS that protects the battery from over charge/discharge, temperature, and short circuit. The BMS is also tested as part of IEC 62619 certification. Invicta 12V200Ah and 12V300Ah also include inverter friendly capabilities.
What warranty comes with the Invicta batteries?
As of 2020, all Invicta batteries have a 7-year warranty available in approved applications. Please see the Invicta Warranty page for full terms and conditions.
Why is Invicta lithium better than an AGM battery?
Compared to an AGM of a similar capacity (e.g. 100ah vs 100ah) Invicta is less than half the weight. They can also be recharged five times faster, have a more efficient use of capacity and double the runtime. Additionally, they can sit unused for up to 12 months.
What is a lithium battery?
Just like standard lead acid batteries, Lithium batteries consist of positive plates (cathod es) and negative plates (anodes) as well as insulating separators to avoid short circuits between the positive and negative plates, and finally electrolyte, which is the conductive liquid although unlike flooded lead acid batteries, there is no free liquid in LiFePO4 batteries. A lithium battery differs in the materials used for the above mentioned components, especially the cathode and also the process undertaken during charge and re-charge. A lead acid battery undertakes chemical reactions, which change their components. Lithium just transfers ions during the charge and discharge process leaving everything else the same.
Do I need to charge a lithium battery differently to a lead acid one?
LiFePO4 batteries operate a bit differently to lead acid batteries, but an appropriate charge is still best for maximum battery life.
A constant current (restricted by the charger output) will flow until the battery reaches a charged percentage of 90-95%. Once it reaches this point, the current will reduce and the voltage will increase - rising to a cut-off voltage (in reality around 14.7V).
Why is the LiFePO4 battery used for lead acid replacement applications?
LiFePO4 is the safest form of Lithium in terms of temperature range and when considering overcharging/discharging, short circuit and penetration possibilities. Other benefits of LiFePO4 include:
- High thermal runaway point
- Similar voltage to SLA (3.2V per cell = 12.8V)
- Good all round performance (flexible for many applications)
- Environmentally friendly (phosphate is not hazardous to environment or health)
- Slow capacity loss (sit for longer before re-fresh recharge is required)
- High cycle life
- Cost effective

No, they can be installed in any rotation and in the same location as your current Lead Acid. However, please note that the BMPRO Invicta Lithium range is NOT suitable for under bonnet applications.
What is the integrated battery management system (BMS) for?
The Integrated Battery Management System in Invicta Lithium Batteries ensure protection against over-charge / discharge, temperature and short circuits.
Why is LIFEPO4 safer than other lithium battery types?
The LiFePO4 batteries are the safest type of lithium batteries. Phosphate based technology possesses superior thermal and chemical stability which provides better safety characteristics than those of Lithium-ion technology made with other cathode materials. Lithium phosphate cells are incombustible in the event of mishandling during charge or discharge, they are more stable under overcharge or short circuit conditions and they can withstand high temperatures. LifePO4 has a very high thermal runaway temperature when compared to the other types at approximately 270oC as compared to as low as 150oC. LiFePO4 is also more chemically robust when compared to other variants
Are all lithium batteries the same?
The term “Lithium” or “Lithium Ion” refers to a family of batteries in which ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge and back again when being charged. The point to note in this definition is that it refers to a “family of batteries”. Just like Lead Acid family which contains Absorbent Glass Mat (AGM) and Gel types, there are a number of different “Lithium Ion” technologies within the Lithium Ion family. They each utilize different materials for their cathode and (to a lesser degree) anode and as a result exhibit different characteristics, which makes some more suitable than others for different applications.
Can the Invicta Lithium Range be connected in series or parallel?
There are strict conditions that need to be met for the Invicta Lithium Range to be connected into series or parallel systems.
Please note the following:
- Not all SNL batteries can be configured into a series or parallel system. Have a look at the part number of the battery. If the part number contains an "S" as a suffix (eg. SNL12V100S) then the battery can be configured into a system of up to (not exceeding) 4 batteries in series.
- If the part number does not have an "S" as a suffix (eg. SNL12V100BT) then series configuration is strictly prohibited.
- All Invicta Lithium Batteries can be configured into a parallel configuration up to 4 units in parallel (there are specific conditions to a parallel setup - refer to the instruction manual)
Is the cost of ownership of an Invicta Lithium Battery lower than an SLA?
Yes, the total cost of ownership of an Invicta Lithium Battery is lower than that of an equivalent SLA:
- Save up to 50% in battery hardware costs over the life of the system
- Reduce labour replacement costs by up to 7 times
- Greater capacity utilisation allows reduction in overall system size or greater output from your current system size
