What’s the best switch setup for a single 5 cell pack?
You can save a bit on weight by using two HD ‘standard’ type switches with charge leads and then add one ‘Earnst’ type charge port to get ESV and charger access to the pack. Alternatively, you can use two of the larger ‘chargeport’ type switches, this allows you to plug your ESV in to watch your voltage while the charger is plugged into the other port. If you were not counting grams, this would be a better route.
