Victron Energy Skylla-IP65 24/35 3-Bank 120-240VAC Battery Charger [SKY024035100]

Victron Energy Skylla-IP65 24/35 3-Bank 120-240VAC Battery Charger [SKY024035100]

A powerful, waterproof and intelligent battery charger with a 7-stage adaptive charge algorithm, suitable for a wide range of battery types and chemistries featuring a dedicated Lithium-ion charge algorithm.

The wide range universal input voltage adds flexibility to the installation, the charger will maintain its full output power no matter where it is located in the world.

The IP65 rating makes this charger especially suitable for marine, mobile, and industrial applications and it can withstand the rigors of an adverse environment: heat, humidity and salt air.

Both models are available in two versions:

• 3 full rated outputs
• 1 full rated output together with an isolated 3A trickle charge output for a starter battery

Models:12V/70A & 24V/35A

Once purchased and in use, this product is non-returnable.

Product Warranty

Victron Energy Product Warranty

Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end-user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead-acid batteries; 2 years from date of purchase by the end-user, with a maximum of 30 months from the Victron Energy invoice date, Lithium batteries; 3 years from date of purchase by the end-user. In addition to this, proof of correct battery usage is required when making a battery warranty claim.

For a 10% surcharge on the net price for products that came with a 5-year warranty, an additional 5 years of warranty can be purchased, bringing the total warranty to 10 years. Warranty extensions need to be applied for ultimately one year before expiration of the original term.

During the warranty period, Victron Energy will, at its discretion, repair, replace or credit the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation, and re‐installation. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like:

• Reverse of battery polarity.

• Inadequate connection.

• Mechanical shock or deformation.

• Contact with liquid or oxidation by condensation.

• Use in an inappropriate environment(dust, corrosive vapor, humidity, high temperature, biological infestation...). 

• Breakage or damage due to lightning.

• Connection terminals and screws destroyed or other damages, like overheat, due to insufficient tightening.

• For any electronic breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state of the internal control diode and/or the input/output X and Y capacitors determine the warranty.

This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone else than Victron Energy or one of its authorized Repair Centres. In order to qualify for the warranty, the product must not be disassembled or modified.

Repair, replacement or credit are our sole remedies and Victron Energy shall not be liable for damages, whether direct, incidental, special, or consequential, even caused by negligence or fault.

Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers when performing warranty repairs or building replacement products. If Victron Energy repairs or replaces a part of a product, its warranty term is not extended.

All remedies and the measure for damages are limited to the above.

Victron Energy shall in no event be liable for consequential, incidental, contingent or special damages, even if having been advised of the probability of such damages. Any and all other warranties expressed or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, including but not limited to implied warranties of merchantability and fitness for a particular purpose, are limited in duration to a period of five (5) years from the date of purchase, with the exception of batteries. For lead acid batteries a two (2) year period applies and for lithium batteries a three (3) year period applies.
