📌 Overview
Meet the industrial-grade charging solution from Henryuan Electronic Co., Limited. Our premium 29.4V 10A Lithium Battery Charger (Model: HRY29410000) is precisely engineered to provide rapid, safe, and intelligent power delivery for all 7-Series (7S) 24V nominal Lithium-ion (Li-ion) battery packs.
Built for high-demand heavy-duty applications—including industrial AGVs, automated warehouse robots (AMRs), electric mobility scooters, commercial floor scrubbers, and electric outboard motors—this 294W charger combines ultra-high current output with uncompromising global safety standard compliance.
🚀 Key Technical Advantages
Pure Hardware 3-Stage CC-CV-Trickle Algorithm: Unlike generic software-controlled power supplies that suffer from digital jitter, Henryuan utilizes robust, pure analog hardware feedback loops. It locks the bulk current at exactly 10A, switches seamlessly to constant voltage at the 29.4V threshold, and terminates safely when current drops below the cutoff, extending cell lifecycle longevity by 10%–15%.
Surgical Voltage Cutoff Accuracy (±0.2V): Lithium chemistries have zero tolerance for over-charging. Our strict ±0.2V charging precision ensures maximum pack saturation while preventing the battery pack's internal Battery Management System (BMS) from entering emergency over-voltage protection lockouts.
Advanced Fanless & Dust-Proof Thermal Topology: Active cooling fans represent the single most common failure point in harsh warehouse or industrial fields; they draw in abrasive dust, moisture, and debris. Henryuan achieves high conversion efficiency (>88%), allowing the 294W hardware core to dissipate heat purely through passive natural convection cooling enclosed in a completely silent, sealed PC V0-grade fireproof housing.
The "Frozen PCBA" Sourcing Commitment: To eliminate unannounced component degradation or material "skimping" across multi-year global supply contracts, Henryuan enforces a strict BOM-locking (Bill of Materials) framework. Once your engineering team certifies the initial 29.4V 10A prototype, the internal board layout, component brands, and circuitry are 100% permanently frozen across all future mass-production batches.
In the event of an external field anomaly, our internal printed circuit board assembly activates an ironclad analog safety layer within less than 0.1 seconds:
Short-Circuit Protection (SCP): Instant auto-cutoff with automated hiccup-mode recovery upon fault removal.
Over-Voltage Protection (OVP): Clamps output boundaries to prevent transient voltage spikes from burning delicate components.
Over-Current Protection (OCP): Locks the current threshold firmly to prevent over-amperage heat damage to battery cells.
Reverse Polarity Protection: Safeguards the circuitry if the user accidentally reverses the positive/negative terminal connections.
As a seasoned, engineering-first manufacturer since 2012, Henryuan provides flexible hardware customization to streamline your system assembly:
AC Wall Plugs Available: US, EU, UK, AU, JP, KR, CN, and custom detachable cords.
DC Output Connectors Available: XLR (3-Pin), Anderson Powerpole (PP15/30/45/SB50), D-Tap, Aviation Plugs, 3-Pin Inline, Alligator Clips, Ring Terminals, and various DC barrels (5.5mm x 2.1mm / 2.5mm) precisely matched to your BMS layout.
Q: Can this 29.4V 10A charger be used on a 24V LiFePO4 battery pack?
A: No. A 24V LiFePO4 pack consists of 8 cells in series (8S) and requires an absolute maximum charging cutoff voltage of 29.2V. This charger outputs 29.4V, which is specifically matched to a 7S Lithium-ion (NMC) chemistry. For 24V LiFePO4 systems, please request our dedicated 29.2V charging models.
Q: How do the LED indicators communicate the charging status?
A: The charger features clear dual-color LED diagnostics: Solid Red indicates the constant current (CC) phase or constant voltage (CV) bulk replenishment phase is actively running; Solid Green signals the current has safely tapered into termination, meaning the pack is 100% saturated and the safety cutoff has engaged.
Q: Are production units identical to the samples we test?
A: Yes. Operating under our ISO 9001:2015 certified infrastructure and strict BOM-locking policies, every single unit generated in mass production matches the tested prototype down to the specific component brand. Furthermore, 100% of finished units undergo full-load burn-in testing for a minimum of 4 consecutive hours prior to shipping.
