Maintenance Free
Plug, play, and charge. No watering, no corrosion.
Lightweight & Easy to Transport
Compared to other battery chemistries, RELiON LiFePO4 batteries provide the same or greater energy at less than half the weight and size. This means more flexibility and ease of use!
Long Life
RELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of the rated capacity after 3,500 cycles.
Fast Charging
RELiON lithium batteries charge much faster than traditional lead-acid batteries, and they’re packed with more usable energy so you’re always ready to go!
Partial State of Charge Tolerant
Partial charging does not affect performance quality or battery life. A low self-discharge rate means worry-free storage so even occasional users can be assured of reliable performance.
Constant Power
Full power available throughout discharge. Voltage does not drop like lead-acid.
Eco-Friendly & Safe
RELiON lithium batteries are the ultimate clean energy. No gassing, no fumes, and no pollution. Enjoy reliable power, while protecting the environment, using these non-hazardous batteries.
