Gary Carter at lithium battery supply helped me choose my Rhino battery for my 2020 Polaris Ranger EV. Gary was very helpful and responsive throughout the process of ordering, shipping, and installation of my battery. I would highly recommend Gary and lithium battery supply to anyone considering switching from lead acid to lithium.
Let's be honest, you can buy this battery kit from multiple places online. However, you likely are not going to get the same level of customer service as you will here. The level of communication is second to none. I got several shipping updates via text. I reached out after the sale for some support and received replies well past 8:00 pm. If they sell it and you're buying, buy from Gary
Had it running constantly for 4 weeks now and it awesome. The charger runs for about 2 hours a day and a constant load. The staff was the best part above the heat quality of the battery. Thanks Epoch
Gary Carter is a throwback to what customer service used to be
Gary Carter is a throwback to what customer service used to be. He followed the sales process all the way through to installation. He even asked for post install pictures. Unfortunately most sales now end when your check clears. Not Gary. He showed genuine interest all the way. Keep on redeeming the sales profession. Thanks for everything.
