You can use a normal DC/DC inverter hooked up to battery or grid and charge with as long as you keep an eye on it.

Example: http://www.ebay.com/sch/i.html?_from=R40...5&_sacat=0

There are others of course. But i would not charge multiple in series. Only 1 cell at a time or multiple in paralell.

You're right, it is 3.65 per cell fully charged.

The balancing process I have been doing called for the battery to be charged together.(all cells ie 12v).

Sorry rookie error on my part  Angry I was only outputing 3 amp on the imax, when i increased amps to 6, I got full charge.

I don't really think the imax is up to balance charging these batteries.  I'm sure the charger/bms that came with the cells would do a great job but needs some further wiring, has a different plug etc.

Thanks for your response  and the link Smile,

Hi all,

Hope you all have a good easter!

A bit of an update on these batteries.

I have connected 3 x 60 ah pack in parallel (180 ah @ 12v) and have been cycling these. I picked up a 800w victron inverter to create some loads.

I've been checking out the BMS I  got with the cells, it's a Ligoo EK-FT-51. While I haven't been able to find much online on this specific model, I  have found user manual and quick start guide for a very similar model.

Initially I was thinking I would sell the BMS and charger but am now thinking I might use the BMS, most of the cables and wires are eitther connected or labelled.

As it appears to be designed for a 48 volt system, this is what I will probably go with. Thinking i will use the 16 x 100 ah cells for this and maybe add the 60 ah cells later.

I will have some questions when I get  to setting it up and would really appreciate any help/ advice any of you guys may be able to offer. Smile

I'm thinking i might start a youtube channel to share my journey and seek advice guidance from the wider community.

I still only have 140 watts of 12 volt PV but am hoping to have at least 1 kw of panels soon.

Feel free to comment, any advice welcomed.

Hi powerwallers,

Just sharing two short video updates I made today on the CALB LiFePO4 cells, now that I'm a big shot youtuber Tongue and a bit of an update on my solar setup  Smile
