Plug in and replace

Fitting your new lithium-ion battery couldn't be easier. Far superior in every way, Transporter Energy batteries are a standard size and use universal connections, so they are straightforward to swap for lead-acid units.

These batteries charge 12 times faster than a traditional battery and have a rugged, sealed casing makes them durable and suitable for use in a range of different environments. No maintenance is necessary and with a lifespan of up to 10 times that of a traditional battery, you really can plug in and go!

The Victron Connect power monitoring app

Power monitoring everywhere

The Victron Connect app gives you the power to monitor and configure your battery wherever you are. Get instant data from your solar charger or battery monitor including charge level, load status, battery temperature, voltage and AC output. Stay in control wherever life takes you, and configure your battery from your smartphone in just a few clicks.

The designed and assembled in USA logo

Designed and assembled in the USA

Quality is at the heart of every Transporter Energy battery. Developed, designed and manufactured in the USA, our batteries are at the forefront of this revolutionary technology.

One of the earliest adopters of lithium-ion technology was NASA; thanks to their light weight, efficiency and safety, they are ideal for use in space exploration. Those same characteristics make our batteries perfect for a host of more down-to-earth applications.

The CE approved logo

CE Approved

Transporter Leisure batteries are the only lithium-ion leisure batteries with CE approval in the UK and Europe, and Intertek. Intertek is the only independent testing house, while most manufacturers certify their own product.

Safety and quality have always been our top priorities, and rigorous research and testing is carried out to ensure our products always reach the highest possible standards.

Our battery is the only lithium leisure battery to have passed Intertek’s highest assessment first time, a standard which demonstrates it is safe enough to be transported by plane; a rare honour indeed.

100% use for longer

Flexible and dynamic

Lithium-ion batteries can discharge almost 100% of their power without suffering any loss of efficiency, giving you up to 50% more usable power than a traditional battery. Less time spent charging means more time doing the things you love.

And Transporter Energy batteries will still be going strong, even after years of constant use. They retain up to 80% of their rated capacity, even after 5000 cycles; that’s a life of around 13 years.

Unmatchable performance

Transporter Energy lithium-ion batteries have an exceptional depth of discharge, with 80-100% usable energy per cycle – that’s up to 50% more usable capacity than some lead acid batteries. What’s more the power is consistent throughout the discharge; voltage doesn’t drop as it does with traditional batteries. There’s no loss of performance for up to 5,000 80% discharge cycles, so you receive optimum power for longer.

Faster charging time

You don't want to spend your leisure time sitting around waiting. Lithium-ion batteries can be charged up to five times faster than traditional lead acid batteries, meaning you are on the road, on the water, or on the golf course in no time at all. And what’s more, Transporter Energy batteries will hold their charge for up to a year with no detrimental effects, so you can prepare them in advance and head straight out for adventure.

Two thumbs up

10 years warranty as standard

The last thing you want to be worrying about is your battery. That’s why Transporter Energy gives you a market leading warranty which covers the battery for any manufacturing defects for up to 10 years, or 5000 cycles at 80% discharge, whichever is sooner. In the unlikely event that you need to claim, we will replace the battery or give you a refund towards a new one so that you can get on with enjoying your leisure time.
