They do have an earlier connecting pin for grounding that can be used, as mentioned.
I just bought the whole kit 1 month ago with the pp45 crimper..... do I bin it?flat tire wrote: ↑Dec 18, 2017 2:19 pmYes you got the wrong connector. The powerpole 45s are total and complete garbage for any rating over a few amps. The inrush to the caps on connection will absolutely destroy them as you found out. Instead look for the SB50 connectors. I run those and they are very solid. You may need to file down the connector after a while if you have particularly hard live connects.
Is there a better solution?Alan B wrote: ↑Dec 19, 2017 2:11 amThe amount of damage in the connector is a function of the voltage and the capacitance. If you have enough of either or both it will damage connectors unless they have anti-spark resistors. If you have enough voltage and capacitance it will burn out the anti-spark resistors, too. They have a limit on what they can handle.
I want to KISS (keep it supidly simple).MrDude_1 wrote: ↑Dec 19, 2017 12:57 pmwhy are you disconnecting and reconnecting the pack on a regular basis?
add a charge connector to the bike, then leave the battery connected, just plug the bike in. the charge plug wont spark if the charger is on first... it will do a tiny one if it is not on.
if you need it for an on/off switch, why not just add one for the logic? If you need a high power switch for whatever reason, get a mosfet based "anti-spark" switch.
but really, why are you disconnecting it in the first place?
