The 320SMART3 is Roamer's 3rd generation 320Ah LiFePO4 battery for off-grid vehicles with high energy demands. The integrated Battery Management System (BMS) with Bluetooth provides remote monitoring via the Roamer BMS app and a market-leading discharge rate of 250A (500A peak) lets you run any domestic appliance up to 3200W via an inverter.

2.5 X The Power of Any Other Lithium Battery Brand

The state-of-the-art cells also ensure stable voltage throughout the charge and discharge curve and a long lifespan of up to 3500 cycles at 80% depth of discharge.

The upgraded BMS will actively balance all internal cells and supports installation of up to four 320SMART3 batteries in series or parallel - with auto balancing for parallel connected batteries. It provides a complete range of protections including low temperature charging.

What We Love About Roamer Batteries

  • Customer Service - we have known Steve, the founder and CEO of Roamer batteries for the past 5 years, following each others adventures. We love working with another company that's been created off the back of Vanlife travels with a real passion for the industry. The customer service from the whole team at Roamer since working with them has been impeccable.
  • Size - we love how small the batteries are given how much power they have. There are a couple of specific batteries that enable us to use tight spots that would otherwise be dead space in the conversions.
  • 10 year warranty - For such a considered purchase, you want to know you will be looked after and the battery will last a long time. 10 years is an amazing amount of warranty...most other large brand lithium battery providers give 5 years maximum.
  • It's never let us down! We live full time in our campervan and we've always had enough power for our needs living off grid and rarely ever have to use hook up.
