The Thumper Lithium LiFePO4 slim line 135 AH has been designed for those hard to fit locations where a standard battery would not be possible to fit.

Offering a huge 135 AH in battery capacity, this set up is available with and without the Bluetooth Smart shunt battery monitor (built internally).

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 LiFePO4range 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.

What feature this battery has that no other brand does?

The best feature of this battery is the capability to link it to any other brand Lithium battery! That's right! Usually lithium batteries require linking only to same SKU or to same make and model Lithium in order for the two cells to work in harmony.

We have changed the game with the Thumper Lithium!

The comprehensive BMS system within this Thumper Slim line model will allow the battery to link to any other LiFePO4 cell. The batteries will equalize (bulk charging first to the battery that requires the most charge) and will work to run in parallel, allowing the use of a single charging source.



• Slim line design
• Proven quality and reliability
• Higher voltage maintained for longer run times with appliances
• Compatible with chargers with an AGM or lithium setting
• For best results: Use of a lithium charger is recommended
• 3 year warranty
• Increased cycles compared to traditional lead acid
• Half the weight of a traditional lead acid battery
• Parallel connection is non-limited
• Designed to be wired in series 12 V ~ 48 V
• Designed to allow linking to any other brand lithium battery.
