Newmar Lithionics Expansions: Add Capacity to Your Factory Bank

Many Newmar diesel pushers leave the factory with Lithionics lithium, and those systems have room to grow. We've been an authorized Lithionics dealer for over ten years, and as Quartzsite's exclusive Lithionics dealer, we add matching Lithionics batteries to Newmar coaches, convert AGM coaches to a factory-style Lithionics system, and add solar and Victron charging so you can leave the generator off.

How the factory system works

Newmar's factory Lithionics systems, and where they have room to grow

Lithionics comes standard on the Newmar Essex, Newmar's top of the line, and is available on other Newmar models. On the Essex, Newmar also offers a third Lithionics battery as a factory option, so if your coach left the factory with two, there's a ready spot for a third.

Factory setups vary by model and year. We see both 630 Ah and 320 Ah Lithionics modules, paired with an external 400 A BMS. On models below the Essex, there's room for a 320 Ah module right next to the factory 630, an easy way to add capacity.

The Lithionics BMS is set up through the Lithionics Bluetooth app and reports to the coach's system over the RV-C network, and we configure it as part of the job.

Not sure what your coach has? Call 520-261-2950 with your year and model and we'll help you find out.

The external NeverDie® BMS at a glance

The external BMS on Newmar factory Lithionics systems, and on some Winnebago models, is the Lithionics Single Channel NeverDie® BMS.

What we can do

Ways to expand the Lithionics system in your Newmar

Every coach is a little different. We look at what's in your bay, how you camp and what you want to run, then plan the expansion around it.

Add a third Lithionics battery

On the Essex, Newmar offers a third Lithionics battery as a factory option, so many Essex coaches have a ready spot for one. We add a matching Lithionics battery to grow the bank.

Add a 320 Ah module next to the 630

On Newmar models below the Essex, there's room for a 320 Ah Lithionics module right next to the factory 630 Ah module.

Convert an AGM Newmar to Lithionics

Coach left the factory with AGM batteries? We can convert it to a factory-style Lithionics system, like the 2022 New Aire below.

Add solar and Victron

More battery is only half of it. We add roof solar and Victron Energy charging and monitoring so the bank actually gets refilled off-grid.

Why Lithionics

Why Lithionics is the battery to expand with

Lithionics is the lithium many Newmar coaches come with from the factory. Here's what you get when you expand with matching Lithionics batteries.

Starting and deep-cycle

Every Lithionics battery is a starting and deep-cycle battery, so a Lithionics bank works with your coach's dash boost ("aux start") switch.

UL 1973 listed

Lithionics batteries carry a UL 1973 listing for the complete, fully assembled battery, not just the cells.

Air-shipped overnight

Lithionics batteries can be shipped by air, overnight, anywhere in the USA and into Canada, so if a battery is ever needed on the road, it can get to you fast.

Newmar Class A coaches

Lithionics upgrades for the Essex, New Aire, Mountain Aire and London Aire

We work on Newmar Class A diesel pushers every season. Equipment varies by model, year and the options the coach was ordered with, so we confirm what's in yours before we plan anything.

  • Newmar EssexLithionics is standard, and Newmar offers a third battery as a factory option. We've expanded an Essex to six 320 Ah modules.
  • Newmar New AireLithionics is available, and some New Aires left the factory with AGM batteries. We converted a 2022 New Aire from AGM to a factory-style Lithionics system.
  • Newmar Mountain AireDepending on year and options, your coach may have AGM or a factory lithium system. We can expand an existing Lithionics bank or convert from AGM.
  • Newmar London AireSame story: we'll check what your coach came with, then expand the lithium bank or convert from AGM, and add solar and Victron if you want it.

Other Newmar Class A coaches too. Tell us your year and model when you request a consultation.

2023 Essex: from two Lithionics modules to six

This Essex came with dual 320 Ah Lithionics modules and room for a third. The owner added the third, then needed more, so we added three more for six 320 Ah modules in all. We modified the battery rack in-house to carry the bigger bank.

The owner had also been dealing with cables getting extremely hot. When we tore into the bay we found the cause: the plans for the coach's dual Xantrex SW3012 inverters call for double 4/0 or 350 MCM cable from the BMS to the bus bars, and the factory had used single 4/0 with hammer crimps. We removed those cables and made new ones with tinned copper lugs, crimped on our hydraulic crimper.

2022 New Aire: factory AGM to a factory-style Lithionics system

This New Aire left the factory with 6V AGM batteries. We converted it to dual 630 Ah Lithionics modules with built-in heaters and a 400 A external BMS that talks over the coach's CAN bus network. We configured the lithium clone file and uploaded it into the coach's Silverleaf system, so it runs its new bank like a factory lithium Newmar.

We also added 2400 W of solar on custom 80/20 aluminum racks, bolted to the factory roof-line gussets, with dual Victron SmartSolar MPPT charge controllers, a Victron Lynx Distributor, a 5k Quattro inverter/charger, a Cerbo GX and GX Touch 70. Besides 80/20, we also build racks from 6061 aluminum.

Questions

Newmar Lithionics FAQ

Can I add a third Lithionics battery to my Newmar?

Often, yes. Newmar offers a third Lithionics battery as a factory option on the Essex, so an Essex with two often has room for a third. On models below the Essex, there's room for a 320 Ah module next to the factory 630. Call with your year and model and we'll tell you what fits.

Will an expanded bank still work with my coach's system?

The Lithionics BMS is configured through the Lithionics Bluetooth app and reports to the coach's system over the RV-C network. We set it up as part of the job.

My Newmar has AGM batteries. Can it be converted?

Yes. We converted a 2022 New Aire from factory 6V AGM to a factory-style Lithionics system that runs like a factory lithium Newmar.

Do you add solar and Victron at the same time?

We can. Many Newmar owners add roof solar and Victron Energy charging and monitoring along with the batteries, so the bigger bank gets recharged without the generator.

Will a lithium house bank work with the dash boost ("aux start") switch?

With Lithionics, yes. Most motorhomes have a momentary boost switch on the dash, often called "aux start." If the chassis battery is dead, you hold it down to jump-start the engine from the house battery without leaving the driver's seat. Every Lithionics battery is a starting and deep-cycle battery, so a Lithionics bank works with the boost switch. As with any job, we still look over your coach's setup.

What if I need a battery while I'm on the road?

Lithionics batteries can be shipped by air, overnight, anywhere in the USA and into Canada. If a battery is ever needed on the road, it can be air-shipped overnight. Call us at 520-261-2950.

When can I bring my coach in?

The shop is open mainly October through April. Consultations and troubleshooting support are year-round, so you can plan ahead in the off season. Request a consultation or call 520-261-2950.
