Core Overview
The UP-H28 is an intelligent charging management device specially designed for drones/agricultural sprayer drones, supporting "one-drag-four" simultaneous charging. It can automatically detect battery remaining power and charge in order efficiently. Used with UP1800-14S/UP2800-14S chargers, it is suitable for 12-14 cell lithium battery packs, featuring high compatibility (supports LiPo/LiHV batteries) and 28A high current carrying capacity, significantly improving multi-battery charging efficiency and safety.
Core Technology Advantages
Intelligent Charging Management
Automatically detects the remaining battery power and charges in order from high to low, automatically switching to the next battery when full, eliminating the need for manual rotation.
Efficient "One-Drag-Four" Design
A single device can simultaneously connect to 4 battery groups (12-14 cells), greatly reducing charging time for multiple batteries and improving operational continuity.
Usage Recommendations
- Charger Pairing: Must use UP1800-14S or UP2800-14S chargers. Avoid using mismatched chargers to prevent low charging efficiency or device damage.
- Battery Configuration Specification: Only supports 12-14 cell battery packs (e.g., 12S1P). The single battery voltage must be within 44.4V range. Ensure consistent parameters.
- Charging Order Optimization: The device automatically sorts charging by power level. It is recommended to connect all batteries after operation, prioritizing recharging high-power batteries for quick recycling.

Frequently Asked Questions (Q&A)
Q1: Can the UP-H28 be used independently?
A: No. It must be used in conjunction with a UP1800-14S or UP2800-14S charger; otherwise, the charging function cannot be started.
Q2: Does it support non-12-14 cell batteries (e.g., 6S batteries)?
A: No. The device is designed specifically for 12-14 cell battery packs. The voltage and circuit matching must strictly comply with the specifications.
Q3: When charging four batteries simultaneously, will the charging speed decrease?
A: No. The device charges one battery at a time in sequence (not in parallel), but automatically switches upon full charge. The overall efficiency is higher than manually rotating single batteries.
