RV Battery, Caravan Battery, Motorhome Battery


Li+AGE DCU series with advanced battery management system will revolutionize your leisure experience. We build our reliable RV, caravan, motorhome batteries to perform better, last longer and provide the deliverable power needed for weekend adventures or full-time boondocking. 


Li+AGE DCU series batteries were designed as drop-in replacements for the most common lead acid sizes on the market, so you can find from 12V to 24V lithium deep cycle battery that works best for you. 


We've performed extensive testing on the leisure industries major suppliers to ensure compatibility. Brands like Victron Energy, Magnum, CTEK, Sterling Power, Xantrex,  and many more make products that excel in a lithium power system. Our experience enables us to assess your current batteries and components and allows us to build a Lithium battery system to power your future adventures. Whatever you need RV battery, caravan battery, or motorhome battery. DEFORD has the batteries, components and knowledge for your lithium upgrade. 



How to design an advanced lithium 

battery system for RV, caravan, or motorhome application? 


A lithium battery system is composed of three critical parts like cells, battery management system and battery case. 

Our talented engineers are expericned in development, or selection of the parts. 


Cell Selection


Our electrochemical engineers with more than 15 years experience are deeply understand all types of secondary lithium battery chemistry, whether in pros or cons. They take so far the safest lithium iron phosphate chemistry, automotive-grade cells coming from EVE, or CATL to manufacture our highly reliable and safe battery systems widely used on RV, caravan, or motorhome.

BMS - Battery Management System


Battery management systems are electronic control circuits that monitor and regulate the charging and discharge of lithium batteries. The lithium battery characteristics to be monitored include the detection of battery chemistry, voltages, temperature, capacity, sate of charge (SOC), state of health (SOH), power consumption, remaining operating time, charging cycles, and some more characteristics. Our talented electrical design engineers with more than 10 years experience are up to the chanllenge to develop more efficient, longer-lasting and more reliable BMS in house.

Battery Case - Mechanics


Most of lithium battery systems are sensitive to work condition like mechanical shock and vibration, or temperature. It is a priority work to design a rugged battery case to protect cells and BMS away from possible mechanical shock and vibration damage. Meanwhile our mechanical engineers simulate battery thermal runaway by FMEA, especially when battery heat dissipation relys on natural convection. Keeping battery works in recommended temperature range is necessary to keep it high performance and long life.

How to monitor, or upgrade your Li+AGE RV, caravan, or motorhome battery? 


Users can download the free LiAGE App from App Store, or Google Play to monitor their Li+AGE RV, caravan, or motorhome battery. The LiAGE App can provide battery real-time monitoring, or warnning notification to users. Your Li+AGE RV, caravan, or motorhome battery reserves a data port on lid which can be used to upgrade battery firmware through the bespoke battery monitoring software.
