World Class Safety Features

Ionic Deep Cycle 36V50-EP has 36 volts and a 50Ah capacity and is perfect for powering your deep cycle systems. Ionic Deep Cycle has an internal microprocessor controlled battery management system (BMS) that monitors the key operational parameters during charging and discharging, such as voltages, currents and internal temperatures. Ionic Deep Cycle Batteries can be hooked as many needed in parallel.

Built for Long Lasting, Reliable Power

The Ionic Deep Cycle Battery has a cycle life of 3,000 cycles or about 10 calendar years. Our 36V lithium batteries have a usable capacity of 99% (compared to 50-60% for traditional lead-acid batteries). Our 36V batteries also 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 Deep Cycle 36V Lithium Battery has the best weight to power ratio on the market

At 19.1” (L) x 6.7″ (W) x 9.5” (H) and weighing only 45lbs, the Ionic Deep Cycle 36V battery has the best size to power ratio of any deep cycle battery on the market. Connectors: 3/8 allow the battery to be installed in any direction unlike lead-acid batteries which are fixed. Ionic 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 43.8V and the discharge cut-off voltage is 31.5V. Max charge current is 60A and max discharge current is 60A / 350A(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 41.4-42.3 volts will allow the battery to be fully charged. Chargers that do not exceed 40.8 volts will only charge the battery to 50% capacity or less
