The product links for the regulators on Mark Grasser's website seem to be broken (404), so it's difficult to find out any information for the products.

For daily cycling use 14.4 , 13.5. A slightly higher float Voltage would be nice if there is a setting for that.

4x 170Ah = 680Ah. If you want to charge at 0.2C then 680Ah * 0.2C = 136Amps.

Thanks for the info.

Do you work for Victron, or is this crow sourced? Just wondering how to qualify answers, that’s all.

Thanks again
