Applications
Power for your needs
Choose what you need the power for – and we'll show you what fits.
Power for the whole trip – even without hook-up
Fridge, lights, heating, charging phones and laptops: a lithium battery gives you more usable power in less space and at a lower weight than lead-acid.
- Up to 50% lighter than lead-acid
- Use up to approx. 90% of the capacity
- Monitor your power in the app via Bluetooth
Stable power on board
Instruments, pumps, refrigeration and anchor windlasses need power you can rely on. Lithium keeps the voltage steady until the battery is almost empty.
- Steady voltage under heavy load
- Maintenance-free – no fluids
- Rugged casings
Low weight and power all day long
Less to carry, and the motor performs the same from the first cast to the last – without the voltage dropping the way it does on a lead-acid battery.
- Compact models from 12V 50Ah
- Faster charging than lead-acid
- Over 9,000 cycles at 80% depth of discharge
Save your solar power for the evening
Store the power from your solar panels and use it after the sun has gone down. We supply batteries, inverters and complete systems – including installation.
- Batteries from 12 to 48 V and rack solutions
- Inverters from Victron and Deye
- Installation by authorised installers
One battery instead of many
For golf carts and mobility scooters at 36, 48, 60 and 72 V. A single lithium battery can replace several lead-acid batteries and weighs far less.
- High continuous power
- Stainless steel or aluminium casings
- 3-year warranty – extendable to 8 years
Energy storage for professionals
Large batteries, rack solutions and special batteries for businesses and installers – with inverter communication on selected models.
- CAN/RS485 on selected models

How our batteries are built
Good cells, a smart BMS and a solid casing. We never compromise on the parts that determine how long your battery lasts.

A smart BMS that protects
The JK BMS protects around the clock against overcharging, deep discharge, overcurrent, short circuits and incorrect temperatures – and balances the cells so they last longer.

More power, less weight
A 12V 200Ah battery replaces three lead-acid batteries with the same usable power – at a fraction of the weight and space.
- Up to 50% lighter
- Use approx. 90% of the capacity
Ready for large systems
Rack batteries with CAN and RS485, so the battery can talk to the inverter. For solar, backup and business.

Our story
The story behind LithiumPro
From one man's passion for good batteries to a family business supplying power to the whole of Denmark.

2018
The beginning – our own batteries from day one
Christian Dyrholm founds LithiumPro and builds his own LiFePO4 batteries right from the start: Grade A cells, a BMS that looks after the cells, and solid casings. The goal is high-quality lithium batteries at a price that lets more people take part in the green transition.

Batteries that make a difference
Among other things, Christian supplies batteries to Médecins Sans Frontières in Africa and to the police's speed camera vans in Denmark – jobs where the power has to work every single time.

Tailor-made
Batteries made to measure
Customers with special requirements get batteries built to their dimensions and needs – e.g. for e-bikes, golf trolleys and other niche applications. It's still an important part of what we do.
