| Marking | What it describes |
|---|---|
| V | Voltage. Keep nominal and full-charge values distinct. |
| Ah | Charge capacity. It is not a guaranteed distance. |
| A | Current. Ask which part, conditions and duration the rating refers to. |
V: voltage
Wah lau, this one ah, bike and charger got their own electrical spec. A higher voltage isn’t automatically an upgrade you can drop in.
Don’t play play, these two figures look close but they’re different. Nominal voltage and full-charge voltage are different figures, so keep both where they’re listed and don’t swap one for the other when comparing labels.
Ah: charge capacity
Steady lah, Ah tells you the charge capacity only. It doesn’t tell us whether the case fits or guarantee how far your bike will go.
Aiyo bro, same Ah on two listings doesn’t make the batteries identical. Keep voltage, dimensions, connection and the rest of the specification alongside it.
A: current
Wah lau, amps tell you current, then people anyhow throw the number around. Ask which current we’re talking about: charging, battery discharge or a controller setting?
Confirm plus chop, “80A” with no context leaves half the conversation missing. Keep the original label or specification with the number, including whether it’s continuous or peak.
Aiyo, BMS number look big also cannot anyhow declare the whole pack like that. A BMS rating by itself isn’t the rating of the complete pack; the cells and the rest of the assembly still matter.
Got numbers? Send the labels
Wah, no need decode the whole label like exam paper first. Send the battery and charger labels as they are; for a custom or changed setup, add the controller and motor labels.
Steady lah, we work from the actual details. Better that than turning a model code into a voltage by guessing.
Aiyo bro, replacement battery got more than Ah to check. When comparing replacements, also check the case, mounting and connector; extra capacity isn’t much help if the battery can’t go where it needs to sit.
