Description
Baintech BT-36V-Waterproof delivers professional-grade charging for 36V lithium battery systems in marine, industrial and off-grid applications
This 15A charger outputs 600W through intelligent CC/CV (Constant Current/Constant Voltage) stages optimized specifically for LiFePO4 and LiMn2O4 chemistry. The waterproof, dust-proof and shockproof enclosure protects against harsh Australian environments, from coastal salt spray to remote worksite conditions. Wide 90-265VAC input accepts variable mains voltage across different power sources, while built-in protection circuits prevent overcharge damage that standard lead-acid chargers cause to lithium batteries.
Designed for applications where generic chargers destroy expensive lithium battery investments. The C600S series eliminates float charging that degrades lithium cells, instead cutting charge current to 10% upon reaching 43.2V cutoff voltage. High-frequency switching technology achieves 95% efficiency, reducing heat generation and power consumption during extended charge cycles in enclosed battery compartments.

Features & Benefits
Lithium-Specific Charging Algorithm: Unlike lead-acid chargers that overcharge and damage lithium cells, this charger delivers precise CC/CV stages with 43.2V cutoff for LiFePO4 systems. Eliminates the float charge stage that causes lithium battery degradation and safety risks.
Waterproof Industrial Construction: IP-rated enclosure withstands marine spray, workshop washdowns and outdoor installations where standard chargers fail. Critical for boat engine rooms, caravan external mounts and mining equipment exposed to water ingress.
Universal Input Voltage Range: 90-265VAC input handles generator fluctuations, remote area voltage variations and international power standards. Works reliably whether connected to shore power, portable generators or inverter-generator systems in off-grid setups.
High-Efficiency Power Conversion: 95% efficiency reduces heat generation and wasted power during charge cycles. Lower operating temperature extends charger lifespan and allows installation in confined battery compartments without active cooling.
Comprehensive Protection Circuits: Over-voltage, over-temperature, over-current and short circuit protection safeguard both charger and battery investment. Prevents damage from wiring faults, battery failures and electrical system malfunctions.
Intelligent Charge Termination: Automatically reduces charge current to 10% upon reaching full charge voltage, then terminates without float charging. Maximizes lithium battery cycle life by preventing the continuous trickle charge that degrades lithium chemistry.

Frequently Asked Questions
Can this charger be used with lead-acid batteries?
No, this charger is engineered specifically for lithium chemistry (LiFePO4 and LiMn2O4) with voltage profiles that differ from lead-acid requirements. Using it on lead-acid batteries will result in incomplete charging.
What size lithium battery system does this charge?
This charges 36V lithium systems. Battery capacity (Ah) determines charge time: a 100Ah battery takes approximately 6-7 hours from empty with the 15A output, accounting for efficiency and charge curve tapering.
Is this suitable for marine installations?
Yes, the waterproof, dust-proof and shockproof construction is designed for harsh marine environments including engine rooms and external deck mounts exposed to salt spray.
Does this work with Australian 240V mains power?
Yes, the 90-265VAC input range covers Australian 230-240V mains power, along with generator voltage fluctuations and international power standards from 110V to 265V.
What happens if the battery is left connected after full charge?
The charger automatically reduces current to 10% at full voltage, then terminates without entering float mode. This prevents the continuous charging that damages lithium batteries, making it safe for permanent connection in standby applications.
