Except for the wires seem awfully thin , one item was road tested ( after being charged ) and it did work fine. Less than half size and weight of my old lifepo4 --which reads 71 % after 12 years of use and three days after charged .On the second bought, I trust you PLENTY .Thanks .
First it's not like the picture. It's square. However, it is as specified in thr specifications 185mm = 7.28 inches x 172mm = 6 6.772 inches x 75mm = 2.95 inches on thr store website. This is my fault for not reading rather wanted it rectangular. Checked voltage both 16s4p batteries when received read 57.3 chatged them came to 59volts fully charged. It looks good, but you cannot tell from this shape if actually 16p4s. Looking at the weight, size, voltage its a 20mAh battery for 153.00 x 2 is a good buy. Highly recommend this company to be honest, good communications, delivered on time & worth it. Thanks.
