Re: [Electric Boats] TPPL batteries

Hi Bob,

We use the Northstar TPPL batteries for all of our Thoosa systems that use AGM. The TPPL allows for the higher amperage demand from an electric propulsion bank and also is able to recharge faster. They can be discharged down to 20%, and the new Blue+ Northstars (still make sure you get the TPPL) have the ability to go longer without a charge and not sulfate.

I'm not familiar with the charger you are using, but it is most likely okay as long as it can be set for AGM. A lot of chargers have the ability to be set for the type of battery being charged. For basic installations we have found the ProMariner Quad to be very good since it charges each battery in a 48v bank individually. If you want faster charging though, look at the Victron chargers.

I am converting my Ericson 27 to electric propulsion and have run into a battery delivery snag. I am going with ElectricYacht's QuietTorque 10, Mastervolt Slim Line 200 ah batteries, and a Quick Charge 25 ah select a charge battery charger. I have just about completed building and mounting battery boxes for Mastervolt Slim Line batteries. All of a Mastervolt cannot deliver the batteries until late July, or about half of my Lake Erie boating season. It has been suggested I look into North Star or Oddysey TPPL ( thin pure plate lead) batteries. Supposedly a somewhat new and improved version of AGM. They are virtually of the same dimensions as the slim lines.

Anybody have any knowledge or experience with these batteries. How about charging issues with this combination, or do I need to look for a different charger?

Any help or info is greatly appreciated since sailing season is not waiting for me.

Thanks

Bob
