I have purchased 24 CNFJ-1000 Lead Crystal batteries (See)
http://leadcrystalbatteries.com/media/wysiwyg/Datasheets/2V/Lead_Crystal_Batteries_CNFJ-1000.pdf to be connected in series to give 48 volts for a 15Kw Microcare inverter. A single battery has 4 neg and 4 pos terminals. The configuration is such that it appears that internally the battery is split into two 500AH batteries. I thus get a 2V reading over the LHS two terminals or over the RHS two terminals. There is no reading over the furthest LHS to the furthest RHS terminal.
As I need 48V the batteries need to be in series. Two options exist to do this and advice or hopefully some technical information could be shared with me. Your help will be appreciated. Regards Mark you can mail me marks@easpe.co.za
Method One: Connect each one of the cells from one battery to the next in series for all 24 batteries and put a "bus bar" over the final row of negative and the final row of positive cells with one lead going to the positive input on the inverter and one to the negative.
Method Two: Connected the two center terminals, negative together and positive together of a single battery and then the two outer terminals negative to positive of the following battery. This would make each battery firstly connected in parallel and then in series.
I have been given many opinions by "experts", but nobody has any technical backing. I quite frankly do not have the ability to decide. Can somebody please help.
