Bench Balancing Instrument
NY-FD04AS24G
The simplest of the bench range: a fixed 5 A resistive discharge balancer for 2S–24S packs. Wire every tap to the terminal strip, start it, and it brings the strings down to match without any current to set.
| Balance current | 5 A, fixed (not adjustable) |
|---|---|
| Applicable pack | 2S – 24S |
| Battery chemistry | LTO · Li-ion · LiFePO4 · Sodium |

1 – 7 A NY-FD24SCG-7 · 2S – 24S
Same discharge-only topology as the FD04AS24G but with a 1–7 A adjustable balance current, so you can match the discharge rate to how much capacity has to come off the pack.
0.1 – 14 A NY-FD14AS24CK · 2S – 24S
The highest-current instrument in the range at 14 A, and the only one that can balance upward: a PWM pulse discharge path plus a charge-balancing mode that tops the weak cells back up. Needs an external charger that can be adjusted and stopped automatically.
0.1 – 7 A NY-FD07AS24CK · 2S – 24S
The three-mode CK instrument at 7 A. Same discharge, constant-voltage and charge balancing as the FD14AS24CK, for shops that do not need the extra current headroom.
0.1 – 7 A NY-FD07AS48CK · 2S – 48S
The 48-string version of the CK instrument, for storage and telecom packs that no 24S unit can reach. Runs from a DC 220 V supply rather than the pack’s own voltage range.
Tell the finder your chemistry, cell count and pack capacity and it ranks every compatible model, with the ones that do not fit ruled out and explained. The selection guide compares all NEEY lines side by side instead.
