<b><i>About Ampere Time Battery</i></b><br><br> This high quality powerful lithium battery is an excellent replacement or upgrade<br> for any application currently using a deep cycle Gel, AGM or Flooded Lead Acid<br> battery. The maximum continuous discharge current is 100A and peak discharge<br> current 280A for 5 seconds. We have a professional R & D team and have been<br> committed to providing customers with the perfect power solutions.<br><br> It is light weight, safe and does not release gas when charging, meaning it is<br> kinder on the environment. This battery is suited for a range of uses, indoors or<br> outdoors, as the tough ABS plastic coating resists knocks, cracking and ever<br> changing weather conditions. Our 12V 200Ah portable power station<br> really shines when going camping off the grid. If you are looking for a long<br> lasting and revolutionary battery that won’t let you down then this is it!<br><br> <b><i>Specifications</i></b><br><br> Maintenance free<br> Lifting handle fitted to ensure secure hold when moving<br> Chemistry: Lithium Iron Phosphate (LiFePO4)<br> Nominal Voltage:12.8V<br> Rated Capacity (0.2C): 200 Ah / 2560Wh<br> Cycle life: > 2000 cycles at 100% Depth of Discharge (DoD), up to 5000<br> cycles at 80% DoD<br> Rated voltage: 12.8V (Working voltage per cell: 3.2V)<br> Charge voltage: 14.4 - 14.6V <br> Cut-off voltage: 10V <br> Depth of Discharge (DoD): 100%<br> Standard charge current: 40A<br> Charging time: Approximately 5 hours (from low voltage cutoff)<br> Max continuous charge current: 100A<br> Max continuous discharge current: 100A<br> Peak discharge current: 280A<br> Operating temperatures: Standard 0°C~45°C, Discharge -20°C~65°C,<br> Storage -20°C~45°C<br> Impedance (Max, at 1000Hz.): ≤ 40mΩ<br> Battery dimensions(mm): 521x 238 x217<br> Weight: 22kg<br> Battery Terminals: M8<br> Charging Tips:<br> Use Lithium battery charger to maximise the capacity<br> When charging with solar, select B04 mode on solar regulator
