6. Technical Support, Return, and Refund Policy
Email
OverkillSolar@gmail.com
for technical support.
Our BMS policy is quite simple:
If you need help, I will help.
If it isn’t working right I will replace it.
If it’s totally fried I will refund your money.
This includes anything you did to break it.
Enjoy,
Steve.
