Ultralife has enhanced its URB12400-U1-SMB Lithium Iron Phosphate smart battery to offer a 19% increase in energy (584Wh compared to 492Wh). To reflect the change, the product has a new name - the [URB12450-U1-SMB](https://www.ultralifecorporation.com/ECommerce/product/urb12450-u1-smb/lfp-smart-u1?ce=Valued%20E-mail&cfn=Valued%20Contact&cln=Valued%20Contact&cc=Valued%20Company) - but is still commonly referred to as the smart U1.

Originally launched back in 2017, the smart U1 is specifically designed as an embeddable [battery for medical carts](https://www.ultralifecorporation.com/ECommerce/category/applications/medical/powered-medical-carts-beds?ce=Valued%20E-mail&cfn=Valued%20Contact&cln=Valued%20Contact&cc=Valued%20Company) and comes pre-qualified for use with [Tripp Lite and Ametek Powervar inverters](https://blog.ultralifecorporation.com/blog/ultralife-u1-battery-tripp-lite-ametek-powervar-inverters?ce=Valued%20E-mail&cfn=Valued%20Contact&cln=Valued%20Contact&cc=Valued%20Company).  The upgrade comes at a time when Ultralife is expanding its portable power offering for medical carts; with the launch of the [URS-X5 power system](https://www.ultralifecorporation.com/ECommerce/product/urs-x5/medical-cart-power-system?ce=Valued%20E-mail&cfn=Valued%20Contact&cln=Valued%20Contact&cc=Valued%20Company) and [URB-X5 hot-swappable battery](https://www.ultralifecorporation.com/ECommerce/product/urb-x5/lithium-iron-phosphate-smart-battery?ce=Valued%20E-mail&cfn=Valued%20Contact&cln=Valued%20Contact&cc=Valued%20Company).

The URS-X5 power system offers cart users a hybrid configuration, where the URB12450-U1-SMB embeddable battery can be used alongside the URB-X5 removeable batteries, when longer runtimes are required.  The U1 acts as an energy reservoir, sitting in the base of the cart, providing energy when the URB-X5 is exhausted.

And that energy is now greater than ever, thanks to the upgrade that will help the battery to better serve the medical carts of tomorrow.
