Thumper Battery BMS reset switch
One of the key features in the Thumper range of Lithium batteries is the BMS reset Switch.
The BMS reset switch is fitted to each Thumper Lithium battery to ensure peace of mind when traveling so that you are never left stranded with no power.
Check out our video on the BMS reset switch:
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.
These batteries are quality! Check out the internal BMS on this battery compared to cheaper brands

Bluetooth App - THUMPER BATTERIES
The Thumper App can be found in your APP store as a free download.
Note: Some features of the APP are only available with a passcode

Bluetooth App | Control Screen - Explained:
The Bluetooth app offers the ability to control the charge or discharge loads from the battery by remotely switching ON / OFF the power via the Bluetooth App.
To turn either your charge or discharge loads off, simply switch the blue toggle (blue = ON) to instead show a blacked out toggle.
CHARGE SWITCH - to remotely disconnect all charge loads from the battery. Turning this particular switch OFF will prevent the battery from taking a charge load from any charging source, including the DC battery charger.
DISCHARGE SWITCH - to remotely disconnect all discharge loads from the battery. Turning this particular switch OFF will prevent the battery from running any appliance as it disconnects all loads from the battery. This is the perfect option to use when storing the battery.

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 has a continual discharge rate of 100Amps (1200watts) and the 120 AH has 120 Amp discharge rate as standard. 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 would be a 1200watt / 120 AH would be 1440 watts.
Need a bigger BMS? We can upgrade our BMS boards to higher capacity, so you can run larger appliances from the one battery! See our drop down link for upgrade options on the BMS.
How many batteries do I need to run my Inverter?
150 watt Inverter ~ 1200 watt Inverter = 1 Battery with a 100 Amp BMS
1201 watt Inverter ~ 2400 watt Inverter = 1 Battery with 200 Amp BMS or 2 x Batteries with 100 Amp / 120 Amp BMS
2401 watt Inverter ~ 4800 watt Inverter = 2 x Batteries with 200 AMP BMS or 3 x Batteries with 120 Amp BMS
What would happen if I run over the 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 designed to run in series from 12-48V max 4 in series, no limit in parallel.
We now offer an upgrade option for a 200 Amp START BMS (only available by Phone inquiry 08 8391 3121)
What voltage is fully charged in a Lithium Battery?Approx 13.2 ~ 13.4 Volts is 100% charged in a Lithium battery.
The Thumper Lithium 100 AH now comes includes a in built BLUETOOTH monitoring device. Simply download the free Bluetooth app 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 the use of the free bluetooth app available in your App store.
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.
