Thumper Lithium LiFePO4 batteries are fully sealed and are designed to be mounted on any angle for easy application.
Equipped with an internal battery management system (BMS), the Thumper Lithium offers safe charging and discharging with over temperature protection, under and over voltage cut off protection and also internal short circuit protection.
The LiFePO4 range of batteries are less than half the weight of a traditional AGM battery, whilst still offering all of the benefits of a heavy duty deep cycle.
These batteries are designed to hold the terminal voltage higher throughout each cycle, resulting in an increase depth of discharge and a longer overall run time with heavier draw appliances.

The Thumper is a Lithium LiFePO4 Prismatic battery.
Yes! The Thumper Lithium is designed to be continually charged and discharged fr the purposes of running all accessories, such as fridges, lighting, inverters and more.
Both the Thumper Lithium 100 AH & 120 AH have a continual discharge rate of 100Amps (1200watts). The batteries also have a MAX peak discharge of 300 Amps for 1-3 seconds (surge capacity).
This means that if you are using only one battery, then the maximum Inverter size that would successfully run on the Thumper 100 AH / 120 AH would be a 1200watt.
How many batteries do I need to run my Inverter?
150 watt Inverter ~ 1200 watt Inverter = 1 Battery
1201 watt Inverter ~ 2400 watt Inverter = 2 Batteries
2401 watt Inverter ~ 3600 watt Inverter = 3 BatteriesWhat would happen if I run over the 100 Amps discharge rating?
The Thumper Lithium is protected internally with a BMS (Battery Management System), meaning that it will protect the battery against overcharge / low voltage and excessive discharge drain.
Example: If you connect a 2000 watt Inverter (166Amp total draw) to the Thumper Lithium battery, then the battery would allow you to run UP TO 1200watts (100Amps) from the Inverter. If the draw exceeded this 100 Amps, then the BMS inside the battery would disconnect and cease providing power to your system.
Once the load has been disconnected from the battery, the BMS will reconnect itself within a few seconds and the battery will be ready to use again.Can I mount the Lithium battery on its side?
Yes! The Lithium battery is completely sealed and is designed to allow you to mount on any side.
As with any Lithium battery, it is recommended (when possible) to use a lithium battery charger. Lithium Battery charger chargers charge the battery at a slightly higher voltage and run through compatible charging stages to suit the Lithium's chemistry. Charging your battery with a Lithium compatible charger will help to prolong the life of your Lithium battery by ensuring it is receiving a full rate of charge.
In stating the above, the Thumper Lithium range of batteries are designed to be able to charge from an AGM battery setting.Can I use my portable solar panel on the Thumper Lithium Battery?
The Thumper Lithium is designed to charge from any system that is compatible to charge from either a Lithium or AGM setting.
Providing your solar regulator is designed to suit Lithium or AGM chemistry, then it would be perfectly suitable to charge from your portable solar panel.
The Thumper Lithium Battery will not charge from an unregulated panel as the internal BMS will disconnect any input charge that exceeds 15 Volts.What is the life expectancy of the Thumper Lithium battery?
The Thumper Lithium is rated over cycles. A cycle is the process of charging and discharging the battery. The Thumper Lithium is rated to a minimum of 2000 cycles.
Yes! Both the Thumper 100 AH & 120 AH are designed to be wired in parallel and are non-limited. This means you can build your 12 volt system as large as you desire with use of these batteries!
Can I link a Thumper Lithium 100 AH to a 120 AH ?
No. As the BSM is different in both the 100 AH and the 120 AH, it means the two batteries are not designed to be linked to one another.Can I wire the Thumper Lithium in Series?
Wiring in series converts a 12 Volt battery into either a 24Volt / 36Volt or 48Volt system (depending on how it is wired)
The Thumper 100 AH is not designed to wire in series (only parallel)
The Thumper 120 AH runs a more sophisticated internal BMS, which makes it perfectly suited to run in series UP TO 48 Volts. This battery will allow you to build a 24 Volt / 36 Volt or 48 Volt system.
Approx 13.2 ~ 13.4 Volts is 100% charged in a Lithium battery.
The use of a Lithium compatible gauge, such as the Victron SmartShunt, is recommended in order to accurately monitor the state of charge in a Lithium battery set up.
Using voltage to monitor the state of charge in a lithium battery is unfortunately not accurate.
As the voltage in a lithium battery remains higher throughout the cycle life of the battery, it means that Thumper Lithium will read in the 12's when it is nearing the end of it's capacity. When the remaining capacity of the battery has been exhausted, the battery's BMS will disconnect and the battery will shut down.
The short answer to this is Yes, and No.
A voltage meter will provide you an 'indication' on the state of charge on a lithium battery. However, the slightest change in the digital reading of voltage can mean over 50% of your battery's capacity.
The most accurate method to monitor a lithium battery is by use of a gauge that will allow you to enter in the total capacity of the battery, then monitor the discharge taken from the battery, which will then provide you an estimate of remaining capacity. For example: The use of a Victron SmartShunt / BMV700 or BMV712What does the 12.8V on the front of the battery represent?
Much the same as how a lead acid battery is configured, The Thumper lithium battery is constructed using a multiple of smaller cells linked internally.

AS/NZS 3001.2 | New regulation requirements:
The new regulations for lithium batteries require a few considerations when installing in caravans as of 15.11.2023. It is therefore recommended to take the following recommendation into consideration when installing:
Lithium batteries shall:
- Be installed externally, ie. Behind a wall, compartment or barrier that prevents the egress of gases into the habitable area; and
- Not enter the habitable area of the structure
In order to meet these requirements, it is recommended that lithium batteries be installed as follows:
- Open to the environment, taking into account a suitable IP rating and mechanical protection.
- Located in a battery compartment that is sealed to the enclosed habitable space of the recreational vehicle.
A battery compartment that opens to the exterior should
- Open outward (to the exterior of the connectable electrical installation) and
- Be accessed from the exterior of the recreational vehicle
If access to the battery compartment is obtained from within the habitable space of the recreational vehicle the compartment must have the following:
- Fitted with openings that maintain a full seal from the enclosed habitable space of the recreational vehicle when in the closed/stored position
- Access to the compartment must only be possible by removing screws or using a prescribed tool.
- An adequate seal from the enclosed habitable space of the recreational vehicle must be restored and maintained after removal and replacement of the compartment opening.
Sealing of a battery compartment from the habitable space of the recreational vehicle must ensure the following:
- The construction of the compartment must prevent the ingress of any fumes or gases from entering the enclosed space of the habitable area.
- Any cable penetrations into the battery compartment must be sealed with suitable cable glands bulkhead posts or another form of non-combustible sealing.
- An annex is considered a habitable space of a recreational vehicle. Battery compartment openings should be located outside the expected enclosed space of an annex.
Note the definition of a recreational vehicle by Cambridge university is:
This would include Caravan’s, motorhomes, camping trailers.
