Good battery....awful support! Beware...
I repowered my 48V Polaris Ranger EV with an Epoch 160Ah kit about a year and a half ago, largely based on an online review(by Will Prowse). Solid battery, well-built, intuitive install, smart interface -- genuinely impressed for the first year. Then the wheels came off. Failed wiring harness, then a BMS failure, then another BMS -- all within a dozen cycles on the cells. Three failures in five months. I offered and did the bms swap out myself. I didn't want to burden this small company with shipping a heavy battery, when the swap was easy enough. The battery itself? Seems terrific! The support? Genuinely awful. Hard to reach, slow to respond, vague answers, and -- I recently learned -- they weren't even logging support cases in their system. So, after 6months of calls and emails from me, they had nothing documented(thank goodness that I did) For a $250 battery you might shrug that off. For a nearly $3,000 kit, it's not acceptable. I've worked with them quietly and in good faith for five months. I'm not a whiner. But I've hit my limit. My honest take: great product, but Epoch has grown faster than their support infrastructure can handle. They're just not equipped to back an expensive, premium battery the way a premium brand should. Had such high hopes. Buyer beware on the support side.

I’m a senior manager at Epoch Batteries, and I’m sorry. Three failures in five months on a kit you’ve barely cycled are unacceptable. So is having to chase us for answers, only to learn that your support history wasn’t properly documented. You gave us repeated chances to make this right. You even replaced a BMS yourself to spare us the cost and delay of shipping the battery. We should have met that effort with clear communication and ownership of the problem. We didn’t. I want to take responsibility for your case personally. I’ll review the correspondence and the work already done, arrange a thorough evaluation at our expense, and work with you on a lasting resolution. You should not have to install another part or start your story over with another support representative. If we cannot restore your confidence in the kit, we’ll discuss a replacement or refund. Please send me a private message with your order number so I can locate your case and contact you directly. I understand that a reply here doesn’t undo six months of frustration. We need to follow through.
