# 12V Drone & Robotics Battery Charger — JUXON OEM/ODM
A 12V drone & robotics system lives or dies by its charger. JUXON Power, a Shenzhen charger manufacturer since 2014, builds switched-mode Li-ion units from 48W to 8000W, tuned to the exact pack rather than a generic curve. For a 12V-class drone & robotics pack the real numbers are 3 cells in series — 10.8V nominal, 12.6V at full charge (our representative 10.8V 3S Li-ion build) — charged at roughly 10.0A. The guide below uses our product sheet values, not marketing round numbers.
What a 12V drone & robotics battery charger actually is It is a CC/CV (constant-current / constant-voltage) power supply that takes 100-240V AC and delivers a controlled Li-ion charge. In a 12V system the pack is 3 cells in series (10.8V nominal, 12.6V full). The charger must terminate precisely at that point: overshoot cooks cells, undershoot leaves the pack shallow and the vehicle short-ranged. A purpose-built 12V drone & robotics unit holds the curve across temperature and pack age, which is why a generic laptop brick is a poor substitute.
Specifications that matter (from our product sheet) | Parameter | Value | |---|---| | Output voltage | 10.8V (Li-ion) | | Pack configuration | 3S (10.8V nominal / 12.6V full) | | Typical output | 10.0A (108W) | | Chemistry | Li-ion | | Input | 100-240V AC, 50/60Hz | | Charging mode | CC/CV | | Cooling | Natural convection or fan | | Housing | Black flame-retardant ABS (UL94 V-0) | | Protection | OCP, OVP, OTP, reverse polarity | | Connector | Rosenberger RoPD 6 (auto-dock / with data) M16 / C091 2–4 (<=10A) Anderson PP15-45 | | Reference models | Juxon010-48A, Juxon010-75A, Juxon010-84A, Juxon010-90A and more |
How a 12V Li-ion pack should be charged The charger ramps current to the set value, holds it while voltage climbs (constant current), then holds voltage at 12.6V while current tapers (constant voltage) until the pack is full. That CC/CV profile is what keeps a 3S Li-ion pack healthy over hundreds of cycles. JUXON adds OVP, OTP and reverse-polarity protection so a wiring mistake trips the supply instead of the battery, and the black UL94 V-0 enclosure keeps it safe in a dusty workshop or a wet marine bay.
Connector: get this right and the rest is easy Our sheet lists connector candidates per pack: Rosenberger RoPD 6 (auto-dock / with data) M16 / C091 2–4 (<=10A) Anderson PP15-45. The rule is simple — match the mating plug, then confirm polarity, pinout and any signal/communication pins before mass production.
Where a 12V drone & robotics charger is used Drone & Robotics charging covers drones, rovers and custom robotics packs. From the product sheet: indoor home, office, service stores and small-equipment. JUXON's standard catalog shows e-bike, forklift, mobility and marine models, but we regularly design drone & robotics units to a customer's exact voltage, current and connector — see the drone & robotics product page.Because drone & robotics packs vary widely by airframe and cell format, JUXON treats each as a custom build — the charger's voltage, current profile and connector are matched to your exact battery, not a catalog guess.
How JUXON builds it (OEM / ODM) JUXON Power is a professional lithium battery charger manufacturer based in Shenzhen, Guangdong, China, operating since 2014 across 48W to 8000W with 400+ charger models shipped to 60+ countries. The engineering team runs the full chain — schematic, PCBA, thermal management, enclosure tooling and end-to-end certification — so a 12V drone & robotics charger arrives as a drop-in unit matched to your chemistry and form factor. Low-moq runs with fast sampling (prototypes in 7-10 days).
Certifications for your market For this Li-ion 12V class, typical certifications on the build are KC, PSE, ROHS. The full portfolio JUXON supports end-to-end includes CE (EU), RoHS (EU/eco), UKCA (UK), UL (USA/Canada), TÜV (Germany/EU), TÜV GS (Germany), PSE (Japan), KC (South Korea), plus ISO 9001 / ISO 14001 factory systems. Tell us the target market and we map the exact marks before tooling.
How to size a 12V drone & robotics charger Rule of thumb: charge at 0.2C-0.3C of pack capacity. A 20Ah Li-ion 12V pack → about 4-6A; a 100Ah bank → 20-30A. Size the charger to the pack, not the vehicle's peak draw, and leave thermal margin for summer parking or sealed enclosures. If you are unsure, send the pack label — we return a matched model and a quote, usually within one business day.
Pre-production checklist Before committing to a 12V drone & robotics build, lock down four things: (1) pack nominal and full-charge voltage; (2) cell count and chemistry (Li-ion); (3) the exact mating connector, polarity and any communication pins; (4) target-market certifications. Email those on one line and we return a matched Juxon010-series model with a quote, usually within one business day.
FAQ Q: What voltage does a 12V Li-ion charger actually output? A: It charges to the pack's full-charge voltage — 12.6V for a 3S Li-ion pack (nominal 10.8V). The 'charger voltage' is always higher than the nominal rating.
Q: Can one 12V charger serve both Li-ion and other chemistries?
A: No. Li-ion needs its own CC/CV cutoff. Mixing chemistries on one curve damages cells; we build separate profiles or a selector.
Q: Which connector fits a drone & robotics pack?
A: It depends on the mating plug. Our sheet lists candidates per pack (XLR, Anderson, DC barrel, M16/GX16 and more); send a photo of the connector and we confirm polarity and pinout.
Q: What certifications apply to my market?
A: KC, PSE, ROHS are typical for this class; CE, RoHS, UL cover EU/US broadly, with PSE (Japan), KC (Korea), SAA (AU/NZ) and CCC (China) by market.
Q: What is the MOQ and lead time?
A: JUXON runs low-MOQ runs with fast sampling (prototypes in 7-10 days); standard OEM runs ship in roughly 15-25 days after sample sign-off.
