However, as another user mentioned its top-off (absorption phase) voltage is set to 14.6v. I have found that a slightly lower voltage (e.g., 14.4v) is better for the final charging phase to avoid having the BMS stop the charge when a single out-of-balance cell hits its limit (3.65V).
The conductors are smaller than is typical for those large 50A Anderson connectors and certainly too small for 50A, but I think they are sufficient to handle the max 20A charging rate for the charger.
