ABOUT DCS
Deep Cycle Systems Pty Ltd is a battery technology company located in Tamborine Mountain, Australia.
We specialise in the design and manufacture of lithium battery related technologies such as Battery Management Systems, Cell Management Systems, DC-DC charging systems and solar regulators. These systems are optimised to be installed internally inside battery cases.
We also have our own cell testing and manufacturing arm by which we design and assemble lithium battery packs for our company under the ‘DCS Lithium’ brand and also private label batteries for other companies.
Our focus is currently on the 12V & 24V Defence and Emergency Services market along with Marine, RV, Telecommunications, UPS and 48V standalone systems.
Warehouse order collections must be arranged by phoning the warehouse directly prior to arrival via our 1300 number Option 1. We do not use or respond to Facebook Messenger.

Solar & Lithium Batteries
DCS deep cycle Lithium Batteries deliver safe lithium phosphate energy storage solutions for a wide variety of applications. They are a similar sized battery to lead-acid batteries, which makes upgrading to DCS Lithium Batteries a simple task, whilst offering six times the battery life and less than half the weight of lead-acid batteries.
WHY CHOOSE US?
DCS Lithium Batteries are light weight, yet due to to their superior construction they are very strong and durable, and are able to withstand extreme levels of vibrations and shocks most suited for military, marine & 4WD applications. DCS Lithium Batteries are designed for deep-cycle (cyclic) applications and are a completely dry battery making them spill-proof and leak-proof. They can sit unused for up to 12 months without effecting their performance, and still be able to crank over your engine after this time.
DCS have designed the Deep cycle Lithium Battery range to be more superior in every aspect with our uniquely bolted cylindrical cell design. This not only ensures the highest possible cell conductivity for long life – up to 5000 cycles at 100% depth of discharge (DOD), but also provides superior cooling performance. DCS 12V recreational vehicle (RV) and marine batteries come with a 3 year warranty and our DCS PV solar Storage batteries are backed by a 10 year performance warranty. All DCS Lithium Batteries are manufactured to International Quality Assurance Standard ISO9001 and are also organic, recyclable and pollution free, making them an excellent green energy source.
