As Scott says, the lithium profile holds many potential advantages, particularly for longer term cruisers. The one disadvantage in my mind is that they are too lightweight for the Amel 54 and maybe SM

Thanks Matt, much appreciated. Did you install Firefly batteries in your new A50 or did you make the leap to Lithium? Cheers, Dean SV Stella A54-154

Thank you Michael, that's good to hear. Regards, Dean SV Stella A54-154

I hear and read about so many cruisers with defective Firefly batteries. Its also clear that the manufacturer has usually replaced them under warranty after sending the customer through some testing h

Bill Kinney, maybe you could also 'chime in' regarding Firefly batteries. Are you still happy with them after 2-3 years? Dean SV Stella A54-154

Well that bursts the bubble of having batteries that are more capable than AGM at lower SOC for half the price of LFP AND don't cause the A54 to list more to port. I can't believe my thought pattern a

Slavko, The 240mm height includes the removable terminal posts. Under these is M8 threaded bolt holes. it's important to get the correct size for your compartment !! cheers, Dean SY Stella A54-154

Slavko, I researched Rolls batteries last year and my choice was the S12-128 model, but this was driven partly by the fact that they are drop-in replacements for my existing Zenith AGM's. Rolls batter

Nick, I would recommend balancers as I have personal experience of AGM getting unbalanced, and I believe this should be avoided. Especially since the balancer is cheap. Victron suggest their balancer

Scott, I would definitely agree that changing from Lithium to Lead is highly unlikely, for anyone. I started this comparative investigation because I'm impressed by the Lithium system which came with

Hi Alan, Thanks for your contribution to the pro-AGM argument. We've chatted about the benefits of battery balancing before and we are in full agreement about its value in a series-string based system

Hi Courtney, That's a tough lesson indeed. Good luck with the Relion kit, that's a great amount of power for a good price. Unfortunately I cant get that kind of pricing in the UK. Hi Scott/Brent, Yes

Hi Nick, Sounds like the lead batteries definitely help the list problem! Good analysis, and I tend to agree about it being marginal for part-time cruising. I have a good solar capability, and I'm sur

Hi Scott, Thanks for that info, very helpful. I was wondering about the alternator... I do have the MV Alpha 24/110 Alternator, but I don't know if I have the original or series II regulator. Best inf

Hi Courtney, Thanks for that info. Its good to hear about the Relion brand. Sorry to hear about the AGM's, what happened to kill those so quickly? Hi Bill, Thanks for the info. Unfortunately, Transpor

Hi Elja, You are correct, maybe the Lithium batteries will last longer, but maybe not. we don't really know! I know from experience the AGM's should last 5 years. I think its unlikely that the Lithium

Thanks Brent, The problem I've found is that Transporter Energy don't supply the 24V battery model. They only supply the 12V battery. I've seen good reviews of the Battleborn product in this forum and

Hi all, 12 months ago I ordered 12x new Rolls S12-128AGM batteries to replace Stella's (A54-154) waning 5 year old battery bank. My thinking at the time was that I would seek another 5 years from AGM'

Porter, There is also a possibility that the component is not a capacitor. It could be a varistor. If so, it may be a little more difficult to source. Hopefully Sleipner will wake up soon! Cheers Dean

Hi Porter, Is (was) there only one capacitor in the system? Seems like a 4-brush motor might have at least one more. If so, maybe you can carefully lift one leg off and measure it? I would surmise tha
