We supply and install deep cycle batteries ranging from 55Ah to 250Ah. We also install Lithium-ion batteries that have a Longer Cycle Life, cycle life up to 3,500 times, 5 times that of ordinary lead-acid. They are Lighter in weight, therefore have a high-density capacity, 3 times the capacity of lead-acid batteries under the same volume. They deliver twice the power of lead-acid batteries, even high discharge while maintaining high energy capacity. Has a wider operating temperature range of between -20℃ ~60℃.
