Get one set (2 Batteries) of DKG3-16197-001 iBot 67V battery packs rebuilt. You need to send us your batteries to be rebuilt. This process replaces ALL of the cells inside with new ones. Circuit boards, cases, harnesses, etc. are reused and are not repaired or replaced. Note: Not all battery rebuilding companies are created equal and neither are the materials. Please do your research before choosing to do business with a company. Some are fly-by-night operations that are working out of their homes that could disappear when you need service. Our rebuilt iBot batteries were used by a past US president. We are fully insured and well-vetted within the battery industry. The DKG3-16197-001 iBot batteries are no longer available to be purchased new so you must pick and choose who you will trust them with.
