is anyone else making their own? instead of that bulky and expensive plastic housing, i'm trying double heat shrink over male/female generic connectors. i have substituted a fuse for one connector in each string. this way the string comes apart easy and is fused. For charging i use one male spade, and one female on opposite sides of the bike so they can't ever touch, even in a crash. can't hook it backwards and it is double heat shrinked. costs close to nothing to make.

has anyone checked the voltage drop at rated amps? i'd expect old fashioned twisted copper with a wire nut to be superior. i'm using this old school method where ever i don't need a fast disconnect, but don't want to solder. There should not be ANY voltage drop because the twisted wire doubles the copper at the twist.

Why build a pack from scratch? I buy tool packs instead.

There are hobbyking XT90 anti-spark connectors. They use a 5.6 ohm pre-charge resistor. There is another thread discussing about it here:

Picked up these 0/1ga welding connectors. Much cheaper then Anderson of similar amp ratings.

I'll post back at some point with how well they work out.

Can you weight one pair with plastics?
Want to know how heavy it will be if I will use 3 pairs.

Not much. Somewhere between 1 soft taco and 3 crunchy tacos in weight. :mrgreen:

Just came across this :

OSE 8.0mm ANTI-SPARK CONNECTORS 200 AMP PLUS

I have not verified anything yet regarding the accuracy of the info from above clip. But it sounds crazy @ 200Amp + already.

Still a big WoW @ 150A !!

Considering a small plastic connectors that size.

So we can jump start a car with the palm size Lipo @ these tiny connectors.
