200% might seem like a lot. But it's $50 on top of a battery bank that may cost thousands.
And the risk is real. I bought "the same" JBD BMS from Amazon as a test unit for another project. When I removed the heat sinks only half the FETS were populated on the board. It would easily pass as the same BMS to anyone not taking it apart. $50 is good insurance that you get what you pay for.
Yes, I know that, but when you order a 120A BMS from a cheaper source, maybe you really get the 80A and never know unless you remove the heatsink. That is my point. For a few extra dollars, I know I am getting what I really ordered.
