I to'd and fro'd on this a lot also. I ended up going a single 2p4s with large BMS on my boat. It keeps it simple. I went with 163ah Calb Cells and a 250A Daly smart BMS (total of 326ah capable of 1c charge and discharge). If I went 4s only i'd still need the 250a BMS on each pack to carry the...

Ah in the specs it says 2 years.. another red flag ? Re mixing, I have 2 mppt controllers so I can put a panel on each if different..thanks for the reminder though.. Re shingled cells, any opinion outside of cheap flex panels??

Thanks.. I believe the warranty is 2 years on those... Still not great. I have found another at twice the price but 310w genuine.. that will fit in the space easily with a 5yr marine warranty.. so tempted to go that way as I can possibly add another 185w after.. Steve

Hi Guys I cannot find much info out about these things.. an "Aussie company' is selling flexible shingled cell panels.. they claim 240w (but I understand that they are unlikely to be) Panel here...

I have 326ah of LFP and run 120a charge from a multiplus, I have 2x 50amp DC2DC chargers in parallel for a 100a total charge.. and will be going solar and trying to squeeze 400+w on the boat flybridge. The 100a DC2DC charge is only 1/3 of what the battery can handle, and I chose this way as we...

As I posted earlier I can do 100a.. via DC2DC... mine are 50a each and can be ran in parallel. Re charging direct from the alternator.. using LIFEpo4 batteries with large BMS's you are likely to kill your alternator with the draw the battery will put on the alternator. Alternators unless...

I'm running 2x Enerdrive DC2DC 50amp chargers (I have twin engines 105a Alternators - one DC2DC per engine paralleled at the battery ) the charge current is adjustable so currently running 80a total. I was told by enerdrive to add a relay on the feed to the DC2DC chargers from the crank...

I have a 40ft (older) powerboat and have just gone to the LFP conversion. I added a Multiplus 12/3000 and went with a custom 326ah LFP pack with 250a BMS - NO Solar currently. Once all installed I did a quick test of how long the system would stay up on battery alone. The boat wasnt being lived...

Thanks Snoobler.. All the graphs I had seen were pretty smooth.. its now on a slightly downward trend.. now at 13.04v and 33.9 SOC after 55 hours and 224.5ah consumed.. i'm actually pretty happy as it looks like it will survive 3 days with no input.. solar will help immensely (working on 400w)...

Hi Guys I have a 2p4s CALB celled 326ah battery with a 250A Daly smart BMS. I'm just doing its first discharge and charge (except a few top ups when messing with the installation. Now i'm not thinking anything is wrong... but just curious.. I have a constant load of about 2.7a on the boat...

Another comment would be for your starting batteries.. why not use one DC2DC charger and use a VSR between the 2 batteries.. as I assume they will be fairly well matched type / size wise? Also what is charging your batteries (house) from the engine? What size alternator etc have you got? I...

Im by no means an expert so take this with a pinch of salt... Victron require an ANL fuse or T fuse for the main fuse from the battery.. something to do with a higher interrupt current. The Mega fuses dont cut it as a primary apparently. You may want to fuse the Batteries with a higher rating...

Thanks.. So do I assume that its use either bluetooth or Uart (usb) not both at the same time or is the second black connecter to the right available also for uart? Steve

I have a question re the Daly Smart 250a BMS.. Is it possible to use both the bluetooth and uart cable together? I can do minimal programming over bluetooth.. and from what I can gather there may be a driver at the end of this month to integrate the BMS with the Victron gear.. There seems to...

Thanks Snoobler.. Cells are CALB L173F163 - not much info on them.. the older models had fairly complete manuals these do not.. it does suggest 3.65v per cell so 14.6v and float according to the old cell manual of 13.6 max.. (old charging segment copied in as last picture below.. ) Specs are...
