Lookalikes and how to tell them apart
ZH (1.5 mm) is smaller, XH (2.5 mm) larger and taller. Grove has the same 2.0 mm pitch but a latch, and it doesn’t mate with PH.
| Connector | Pitch | Latch | Per contact |
|---|---|---|---|
| JST PH | 2.0 mm | no, held by friction | 2 A |
| JST ZH | 1.5 mm | no, held by friction | 1 A |
| JST XH | 2.5 mm | no, held by friction | 3 A |
| Grove | 2.0 mm | yes, a tab to press | — |
Before you plug it in
Two-pin JST PH plugs on LiPo cells have no standard polarity: some brands put the red wire on the other side. Check + and − with a multimeter before you plug a battery into a board; reversed, it can destroy the charger or the cell.
Crimp terminals need the crimper die made for their size: pliers crush them and the contact works loose. Housings and terminals of different series don’t mix, even at the same pitch.
The current rating is a maximum per contact, at the wire size the maker states. With thinner wire, or with every contact carrying current, stay well below it.

Frequently asked questions
What is the pitch of the JST PH connector?
2.0 mm between the centres of two neighbouring contacts.
How much current can a JST PH connector carry?
2 A per contact with AWG 24 wire, at up to 100 V, according to JST.
Figures from the makers’ catalogues and datasheets. Ratings are maxima: derate for thin wire and for many loaded contacts.
