I am extremely satisfied with my purchase and these batteries.
Being my first lithium battery purchase It took me a while to decide on a company to purchase my group 24 batteries. LI Think had the most information available during my search and it was difficult if not almost impossible to find bad reviews on this company. I could have gone cheap but my experience is to pay for quality and a good warranty and support services. I wanted BT and self heating as we do travel during the freezing weather and I did not want to go with heating pads or relocate the batteries into interior heated spaces. My packages came quickly with good tracking. The boxes providing protection were well designed to protect the battery in shipping. The documentation provided with the batteries was well written and clear. The initial preparation instructions for the batteries was clear even for someone new to lithium batteries. The blue tooth connections were flawless and informative even showing the individual cells voltages. It also provides current flow and reserves.
After following the initial preparation the cells in both batteries all balanced to within 0.001 volt. Very impressive. The power supplied by these batteries is beyond all my expectations with steady voltage during discharge cycle. If you’re deciding I highly recommend this company and these batteries.
