A walkthrough of battery-build details using archive photographs. Separate photographs may show different builds; this is not a single customer's case history.
Wah lau, from outside u see a box, a handle and some wires.
Confirm plus chop cannot just throw a tray of cells inside, connect, close? A battery build has more to it.
Steady lah, come look what's supposed to fit before we get there.
Box shape also got opinion
Aiyo bro, cells already take space, then connections, insulation, BMS and cables also need space. The enclosure has edges and an opening, and none gets smaller because the customer wants more capacity.
Wah lau, odd shape already headache, then cable direction also matters. There's no point filling a compartment perfectly if the connector has nowhere to go.
Don't play play with the measuring tape ah. We ask for the actual space and the rest of the setup before treating a chosen capacity as a finished plan.
Follow the wires, not the shine
Steady lah, first see where the cells connect, then where the main cables and thinner monitoring wires go. Those are different jobs inside the same pack.
Aiyo, shiny connection can catch your eye until the photo ends. Follow those details across the photos, not just the shiniest connection or a branded board.
Wah, bench instrument in the background look very atas hor. That's an instrument, not a test report, so ask what checks apply to the actual build.
Lid got final say
Confirm plus chop the cable also wants its own space. The connector needs to be accessible, and the finished battery has to go into the space and come back out again.
Wah, that cable exit detail can decide the whole mood. Look at the cable exit on the finished example, then ask the first question again: where is this battery going?
Aiyo, nice casing cannot answer every question. Photos show the physical details; for operating limits and checks, ask for the actual build specification, no need to guess.
Awkward space? Send the tape
Wah lau, got weird space ah? Send the model, usable dimensions, labels and connector photos u already have. Keep ur existing pack closed; these workshop views aren't a DIY guide.
Steady lah, no need every measurement to be perfect first. Send the wide view and tell us what's missing.
