I purchased (2) 100Amp 24V 8S BMS from Overkill solar in January of 2021.
I put them into service the summer of 2021 and they worked flawlessly until very recently where I started to have issues with one of the BMS. I contacted customer support and received some ideas, none of which worked to fix my issue. They then verified my original purchase and sent out a replacement BMS and sent it Priority Mail so that I could receive it quickly. I received my warranty BMS 10 days after originally contacting Overkill with my issue.
Today I installed the replacement BMS and I am back again running at full capacity. I am a penny pincher by nature, but decided to go with Overkill originally because of their warranty and their support documentation. Boy am I glad that I did!
I plan to double my battery capacity this summer and will be purchasing my BMS's from Overkill for sure. Just wanted to pass on my experience to this forum that has been so helpful over the last couple years...
