What Causes Voltage Drop and How to Deal With It
A voltage drop due to wire length isn''t as large of an issue because it doesn''t cause wire overheating. If the wire is long but still the correct size, it WILL have higher resistance, which WILL result in greater voltage drop, but since the resistance is spread across the entire wire, it won''t get any hotter in one spot like a poor connection.
Lithium battery issue
During charging, the measured peak voltage will rise (above the battery voltage) to drive the electrons into the battery. 3 BBs hold about 3000 watt-hrs, so if your charger is rated for 50 amps, this will take 6 + hrs. If it is instead a 25 amp charger, it will take 2x as long, or ~ 12 hrs.

Why does output voltage drop when charging battery? [closed]
At no load, the filter capacitor holds the DC voltage close to the peak secondary voltage (16.5V). The fully-discharged battery draws a high charging current from the power supply and overloads it, causing its output voltage to dip to the battery terminal voltage (close to 9 V) and rise as the battery charges.
