Our lithium-ion batteries have a usable capacity of 99% compared to 50-60% for traditional lead-acid batteries]. LithiumHub Deep Cycle batteries function in the widest range of temperatures with a discharge temperature range (Functional) of –20°C to 60°C (–4°F to 140°F) and a charge temperature range of 0°C to 45°C (32°F to 113°F). Automatically detects if batteries are too cold to take a charge.
The Ionic Lithium Deep Cycle line has the best weight to power ratio on the market
At 12.55” (L) x 6.5″ (W) x 9.22″ (H) and weighing only 34.2 lbs., the Ionic Lithium Deep Cycle 12V125-EP has the best size to power ratio of any deep cycle battery on the market. Connectors: 3/8 UNC Threads allow the battery to be installed in any direction unlike lead-acid batteries which are fixed. Ionic Lithium Deep Cycle Batteries self-discharge rate per month is between 1-3% compared to lead-acid batteries which are about 30%. Max charge voltage is 14.6V and the discharge cut-off voltage is 10.5V. Max charge current is 80A and max discharge current is 100A / 500A(3s). Can be charged with solar chargers. Can be charged with most traditional lead-acid chargers that do not have “Desulfate” mode, provided the current levels do not exceed lithium battery charge specification. Using a traditional lead-acid charger that reaches 14.4-14.6 volts will allow the battery to be fully charged. Chargers that do not exceed 13.6 volts will only charge the battery to 50% capacity or less.
