User manual and guide to professional battery
charging for Starter and Deep Cycle batteries
THIS MANUAL CONTAINS IMPORTANT SAFETY AND OPERATING INSTRUCTIONS FOR BATTERY CHARGER & MAINTAINER: BK 20
DESIGNED FOR WORKSHOPS AND WAREHOUSES
Lithium (LiFePO4) & Lead Acid compatible
IMPORTANT SAFETY INSTRUCTIONS
Please read this manual and follow the instructions carefully before using the charger.
WARNING
•
The bank charger is designed to charge 6/12V lead-acid batteries (LA) or 12V LiFePO4 (LFP) battery from 4Ah to 40Ah and
maintain batteries up to 80Ah.
• We always recommend that you check the Battery Manufacturers specications before using this charger.
• Explosive gases may escape from the battery during charging. Provide ventilation to prevent flames and sparks.
• For indoor use. Do not expose charger to rain, snow or liquids.
• Battery acid is corrosive. Rinse immediately with water if acid comes into contact with skin or eyes.
• Never charge a frozen battery.
• Never charge a damaged battery.
• Never place the charger on the battery while charging.
• Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery or other electrical
part that may cause explosion.
• When working with a lead-acid battery, remove personal metal items such as rings, bracelets, necklaces, watches…
• NEVER smoke or allow a spark or flame in vicinity of battery or engine.
• Do not charge non-rechargeable batteries.
•
In order to reduce risk of electric shock, unplug charger from AC outlet before doing any maintenance or cleaning. Turn off controls will reduce risk.
•
The kit is not supposed to be used by children or by people who are not able to understand the manual, unless they are supervised
by a responsible person who ensures the proper use of the kit.
MAIN FEATURES
•
Fully isolate – 3 dependent bank charge output.
• Auto Detect – Auto-detect for Lead acid or LiFePO4 battery hooked.
• Adaptable charging algorithm – Enable the precise charging algorithm targeted for Lead acid or LiFePO4 batteries.
•
Smart re-activation – Allows it to wake up “dead” LiFePO4 batteries where the BMS under-voltage protection has been triggered.
• Force re-activation – Allows it to wake up “dead LiFePO4 batteries or low-voltage Lead acid battery by Force mode.
• Two voltage mode – Charge 6V or 12V batteries.
• Battery qualication detection – Automatically detect the battery initial voltage.
• Low voltage Start – Activate the heavy discharged battery from as low as 2.0V at 12mode.
• Battery bad cell detection – Smart detection to the battery bad cells and error indication.
• Weak or sulphated Battery detection – Automatically detect the weak or heavy-sulphated battery and error indication.
• Battery desulphation – Manual recondition to the sulphated Lead acid batteries.
• Charging time management – Multiple charging stages and charging time management.
• Pulse maintenance – Long term pulse mode maintenance to keep the Lead acid battery at optimal performance.
• Flexible output cable – Detachable clamps terminal cord sets with SEA connector.
PROTECTION FEATURES
•
Connection spark free.
• Never overcharge your battery.
• Output short circuit or reverse polarity protection.
• Charging timer for each charge phase protection.
• Thermal run-away protection at the battery side.
• Internal over-heat protection.
• Conformal coatings prevent from moisture for the inside circuit board.
• Corrosion-resistant output connectors.
