Review: fast charge - super excellent charger Review: Good quality unit. - Charger seems like a quality build. Purchased and installed on my boat after being recommended by a marine tech in the area. I added the master volt remote unit as the charger was installed below decks and would be tough to monitor. Used blue sea ANL 35 amp fuses on the outputs and a blue sea grounding buss bar in the install. Works great so far. Happy with the purchase. Hoping for good life from my new AGM batteries with help from this charger. Edit to update: After almost a year and a half I'd have to ask myself why I never had one of these on past boats. This is on a trailer boat so I leave the shore power plugged in with a timer inline between the extension cord and the 30amp adapter. After letting the charger top off my batteries initially, I let it run 30min every few days with the timer. Batteries are still as new. Ready to go when I am. The Mastervolt remote control has a nice screen to show the state of charge and current voltage from where ever you mount it, I put mine in the cabin next to the 110V electrical panel, so you don't have to pull hatches to see what's up. Highly recommend. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | MASTERVOLT | | Colour | ['Blue'] | | Item weight | 4 Pounds | | Output voltage | 12 Volts | | Product dimensions | 27.9D x 12.7W x 20.3H centimeters | | Specification met | CE | ## Product Details - **Brand:** Mastervolt - **Color:** Turquoise - **Item Weight:** 4 Pounds - **Output Voltage:** 12 Volts (DC) - **Product Dimensions:** 2.4"D x 5.2"W x 9.2"H ## Images ![Mastervolt 44010250 ChargeMaster Battery Charger, 12V 25A, 3 Banks - Image 1](https://m.media-amazon.com/images/I/61FsHxPEfSL.jpg) ![Mastervolt 44010250 ChargeMaster Battery Charger, 12V 25A, 3 Banks - Image 2](https://m.media-amazon.com/images/I/51M7JiM9FJL.jpg) ![Mastervolt 44010250 ChargeMaster Battery Charger, 12V 25A, 3 Banks - Image 3](https://m.media-amazon.com/images/I/51taFzMa4rL.jpg) ## Questions & Answers **Q: I have three 12V Cranking batteries and one 12V deep cycle can these all be charged by one on board 4 bank charger?** A: Yes I charge three different banks with a 3 bank **Q: Can this charger charge AGM batteries?** A: Yes. According to the manual it charges: Flooded, AGM, Gel, MLI, Flooded traction **Q: Is there a setting for AGM batteries or does the unit automatically adjust?** A: There is an AGM setting. I’m using my charger on a set of AGMs and it’s been an excellent unit. I also put in the remote control head so I don’t have to stick my head back under the deck to check status. The remote head is also excellent. You can control and monitor with it. Overall very happy with this charger and it’s been keeping my AGMs in top shape. **Q: is this charger waterproof?** A: I would not submerge it, or expose it to direct spray.I usually install a shield on top to protect it from dripping water from above. ## Customer Reviews ### ⭐⭐⭐⭐⭐ fast charge *by A***R on 26 May 2021* super excellent charger ### ⭐⭐⭐⭐⭐ Good quality unit. *by T***O on 24 August 2020* Charger seems like a quality build.
