Update:I originally wrote a very angry review back in April 2025, at which time I had an awful experience with this company's support. I eventually got all the parts and got the mower mostly working (the battery gauge died within weeks of the installation and for some reason the mower only turns on after being plugged in momentarily), but I was frustrated by the mix-ups, delays, and difficulties I had with their staff. However, in January 2026 someone reached out to follow up with me, explaining that they'd gone through some growing pains as the business expanded, but were trying to follow up with anyone who wasn't satisfied. Within an hour they sent me a partial refund for my inconvenience, and promised to send a new gauge and instructions on installing it. It appears that Epoch is working on improving their service and support, and I appreciate the effort. I am hopeful that they keep it up!From my original review: I bought a kit to convert a Ryobi lawnmower, but it took over a month. The plusses: like others, I appreciate that my lawn mower is working again and has more power and pep. When installed, the kit is great and I’m really hopeful that it will last longer than the original lead acid battery set. Assuming that it doesn’t need to be replaced in a year or two, it should be more economical than relying on the short-lived (but expensive) lead acid batteries. But as others have discussed, the install is very complicated and the company provides little support. The best option is third party YouTube videos. There’s no way we could have done this on our own, and this conversion was only possible because we have a retired neighbor who has the skills and tools to do it and enjoys this kind of work. It not only requires a good understanding of electronics, but some very specialized tools. This is not a job for novices.
