From battery to vesc…
-
XT90 – rated for max 90A, but can support more quite well.
On the left is the female connector, on the right is the male. (Determined by the metal bits, not the plastic housing)
-
XT90-S (antispark)
Same as XT90, but has a resistor built in which gets bridges the gap first, allowing your ESC capacitors to slowly charge up (without a spark), which then gets bypassed once you plug the connector in deep enough. No spark is safer for your electronics, and doesn’t wear down the connector!
-
XT60 – rated for max 60A
On the left is the male connector, on the right is the female.
-
XT30 and XT30U - rated for max 30A
Almost as small as a JST connector, but can support far more current! Can be soldered to up to a 14 gauge wire!
XT30U is the upgraded version of original XT30 . The main difference is XT30U is lighter. There is no reason to choose the old version over the U version. Both XT30 and XT30U are compatible. It can handle up to 60A bursts with no issue.
This connector is great for auxiliary stuff like connecting your chargeport to BMS, running a buck converter for lights, etc.

AS150 – ???
-
QS8-S – rated for max 200A, anti-spark.
For the charging port
- DC5521 aka 5.5x2.1mm (up to 5A, but most only 2A)
This type of female port is only rated up to 2A. I (@rusins) burned one with a 5A charger
But these ones are rated up to 5A:
- 5.5x2.5mm
In general, it’s easier to stick to DC55521 connectors. The standard 2.5mm connectors can not handle more current than a good 2.1mm connector. Both are capped to 5A officially.
This female port from electricboardsolutions claims to be rated for up to 4A.
- Xt90s and XT60s are also often used. Make sure not to mix it up with your loop key port!!! Always put a fuse in series with your charging port to avoid such disasters.
From the ESC to motors
- 5.5mm bullet connectors (up to 120A)
Good for 120A. Great for big motors! Ideally paired with 10AWG.
Also useful for battery connections (if you know what you are doing).
4mm bullet connectors
MR60
MT60
MR30
MT30
EC5-3 aka 3mm bullets
Data cables
Jst cables (hall sensors and lipo balance cable)
Jst-ph 2mm pitch
Jst-zh 1.5mm pitch (correct me if I am wrong)
