Wiring question - help

[DT98]

I have a 48v 20ah LifePO4 battery to wire up with these components: battery + wire to a fuse holder to a ping provided diode so I can parallel this battery with another. So there are 4 connections before getting to the controller. Is this too many connections to use anderson 45 amp connectors? I like the ability to plug and unplug but I don't want to cause any problems.

Next question, I also have some anderson SB50 connectors and that is the connector on the crystalite 48v 40a controller. Is there a crimp tool for the SB50 connector or is it acceptable to solder this connector using a propane torch, rosin flux and electrical solder?

Thanks for the help/advice.

The voltage drop of a single Powerpole® 30 amp connector is said to be between .016 and .022 volts at 37 amps.

The link below contains both crimping and soldering information for Anderson Power Pole connectors:

Note: it is important that you don't allow any solder to extend beyond the "crimp" section of the connector. This is due to the fact that "excessive" solder can lead to catastrophic cracking of vibration/stress prone wires that extend both to and from the connectors themselves (the Underwriters Laboratories (UL) requires the use of a cable clamp for soldered connections to unsupported leads).

The link below describes some of the various Anderson PP crimping tools:

Thanks for the good information and links. I may eliminate a couple of the connectors if the voltage drop is between 2 - 3 volts from end to end. This is what I needed to know.
