LiTime 12V 100Ah Xtra-Mini Bluetooth LiFePO4 Battery & 10A Waterproof Charger
LiTime reputation is good; the products and packaging arrived in excellent condition and quickly. The pricing was tremendous. Website and product descriptions are great. The battery and charger appear to be top quality and the dimensions are amazing! I struggled a bit with connecting the batt to Bluetooth, but probably my fault because I am not a very techie person. The only reason I went with Four stars is because I have not gotten it hooked it up to my fish finder yet and actually used it. I do not expect any issues though.
