  1. Tony - Well at least the power management panel does tell me the leisure battery volt readings, better than nothing I suppose. It also doesn't proviede a % state of charge, just how many Amps have gone out (goota read the manual a bit more to get a better understanding...) Jen - I'll take on board the comments IRT tips for the solar panel - all great points
  2. Many thanks for the replies so far. To answer some questions: 1. We are putting the boat on the hardstand as we feel it's safer out of the water for 11 months and we don't need to pay for licence fees over this period which equates to about 900 quid. Craning the boat in and out id about 150 quid each way 2. We can't take the batteries home as we live in a land far far away...in lockdown... 3. Monitoring batteries during cruising is via a Sterling Power Management Panel. I have a reasonable (ish..) knowledge of batteries so during cruising I will let the alternators do their thing to get the batteries back to fully charged whilst cruising. Worst case, if I don't quite get them back to 100% whilst cruising for 4-5 weeks, I'll definatley have them at 100% prior to hardstanding the boat 4. The B2B is alreay installed but not working...I didn't really have any intention to replace it but was looking at potentially getting a 200Ah(ish) alternator for our Izuzu 42 from Four Counties Marine when we start our 6 month cruising option, but I thinks that's another topic...just wanted some simple solutions for the short term cruising period first. So it appears the general advice is to potentially go for a 50Wplus solar that should keep the batteries ''alive'' whilst we're away and help out with charging the batteries whilst cruising the 4-5 weeks. Is there anything I should be aware of so I can 'keep' some of the equipment for the solar install in 5 years (the 800-900w system)?ie go for a MPPT to support the bigger system? Cheers!
  3. Cruiser stern style so batteries under the deck near the engine so installation by an expert would be very simple
  4. Thanks for the advice. As the boat will be on hardstand and pretty much "unsupervised'' for 10-11 months, is there anything that can go wrong when left to it's own devices?
  5. I can install a solar sysytem but I'm trying to keep it as simple as possible...also I'm just not sure what the full cost would be for someone to install a small panel including wiring, mounting, MPPT etc etc system noting we will install a new large solar system (about 800-900W) in 5 years when we start cruising 6 months in each season. Maybe I should make some enquires and do some comparisons....any good recommendations?
  6. Hi all, After some advice IRT battery options for short term cruising focusing on keeping things simple and low pricing... Currently have the narrowboat on the hardstand since Nov 19 (just before COVID kicked in) and will not be able to get her into the water until mid next year. When stored on the hardstand the batteries were 5-6 years old and pretty knackered (weren't holding a charge for long), so by about mid next year they be approaching 10 years old and I think completely shot. Our plan is to cruise for only 4-5 weeks per year for the next few years (return the boat to hardstand each time) so what are the best battery options (cheapest) to support this type of cruising, noting that in the medium term (about 5 years) we will cruise on the boat for 6 months at a go and when we start this option we're happy to get a heap of solar and brand new batteries accordingly. So my thoughts were that we're probably best off getting maybe just 2-3 cheapo lead acids (maybe 80 GBP each?) for each cruising season and literally 'bining' them at the end of each season. Whilst at the hardstand I can't connect the boat to mains power to keep the batteries charged nor install a small solar panel (ie 60-80W) to keep them topped up because I imagine this system including installation (MPPT etc etc) will be few hundred quid. I'm trying to keep it as simple as possibly in the short term and I can easily buy and install 2-3 cheapo leisure batteries. As a side note, the boat currently has 6 x leisure batteries but during our short cruising season I think (maybe..) 3 x 110AH leisure batteries should keep up with our electrical needs (won't be operating the freezer or dryer and washing machine only when engine is going...) and since we will most likely cruise most days, this will be a good opportunity fully recharge them each day (2 x 80AMP alternators with Sterling B-B charger). Also will probably need to buy a starter battery each season as well... That said, at the end of the cruising season when we put the boat back on the hardstand for 10-11 months, I know the batteries will be 'flat' when we start our next cruising season, but if I simply recharge them what would the life expectancy be? ie will the 110AH battery now be a 80AH battery because we've it's been flat for a few months as it's capacity has been degraded? Is 80AH even close, higher or lower? Any experiences? It would be great to go down this path but I don't want to begin a new cruising season with batteries that may have significantly reduced capacity from the original 110Ah. Maybe buy 130AH batteries? Anyway, if anyone has any further ideas or input, please let me know, or if I've missed any key info Enjoy cruising the cut, can't wait to be back. Cheers
  7. I have re-checked the engine starter connections (via multiple videos & pictures I have of the boat as I'm currently not on-board) and can confirm 100% that the engine starter battery ONLY connects to the leisure batteries via the negative black cable..my bad and apologies for the mistake. Soooo re-visiting the electrical schematic, it all makes sense in that the positive engine battery cable goes to the engine battery isolator which in turn is connected to the A-B charger... I suppose this means my question is now mute, it is not one large battery bank. Apologies for the inconvenience!
  8. The picture shows the engine start battery with its + & - cables connected to the first of 6 x leisure batteries. When we got the boat the previous owner had issues with one of the leisure batteries and bypassed this battery to the other leisure batteries. I can't fathom why this would mean connecting the engine battery to the leisure bank...but maybe this was already set up this way.. Anyway the main point is that if I disconnect the engine starter battery when I next replace the leisure batteries, I imagine this would not create any further issues with the current charging setup?
  9. I have cut and pasted this question from another topic of mine as it deviates from the original question: I have noticed that the engine battery is connected to the leisure batteries (see photo) which has raised a few questions.. After scrutinising the boats Electrical System Schematic, it appears the setup from the builder is as follows; - 2 x 80A alternators with a Sterling A-B charger and a Bat-Bat charger *Alternator 1 goes to the B-B charger which connects to the Bow battery and also the A-B charger *Alternator 2 connects to the A-B charger which then connects to the Engine battery via the Engine Battery Isolator & the Leisure batteries via the Leisure Battery Isolator So while the schematic has the engine battery and leisure batteries completely separate, why in reality are they connected? Maybe I'm reading something wrong here? I always thought that the 2 x battery banks should be separate so if the leisure batteries ever die, the engine start battery is still good to go as it's on a different system as such. Thoughts? I would normally take a picture of the boats electrical system schematic and post it here but it's very blurry and wouldn't be clear, maybe I'll do another PPT..
  10. Thanks all for the responses and I if I have enough cabling I'll go for the 2-5 setup As I'm unsure of the ratings of the cables and interconnects, is there a recommended rating? Also I have noticed that the engine battery is connected to battery 1 (see photo) which has raised a few more questions.. After scrutinising the boats Electrical System Schematic, it appears the setup from the builder is as follows; - 2 x 80A alternators with a Sterling A-B charger and a Bat-Bat charger *Alternator 1 goes to the B-B charger which connects to the Bow battery and also the A-B charger *Alternator 2 connects to the A-B charger which then connects to the Engine battery via the Engine Battery Isolator & the Leisure batteries via the Leisure Battery Isolator So while the schematic has the engine battery and leisure batteries completely separate, why in reality are they connected?

  11. OK - so my current set-up is like this but is it best to have the installation feeds from batteries 1 and 6 instead of both from battery 4?
  12. Hi again, I have posted this question in a different topic but decided to make separate it for ease of tracking. Question: Any recommendations on the best way to interconnect 6 x leisure batteries? I know there is a preferred method for 4 x leisure batteries (as per Smartgauge website- Method 4: http://www.smartgauge.co.uk/batt_con.html) but what about 6 x batteries? Currently it appears my batteries are done via method 2 but with the main feeds taken from the middle battery. Hope that make sense.... Thoughts? Any advice is highly appreciated. Cheers!
  13. Thanks for all the responses and as the the boat is skin cooled, we will play it safe and leave it as is. Will double check with the marina IRT adequate anti-freeze and make sure when we do start using the boat, we have the engine fully serviced (all coolant, filters, oil etc etc) prior to commencing any cruising. Also all batteries will be dead so will need to replace the 6 x leisure batteries (over 5 years old in Nov 9 and held very little charge) and the engine start battery. If we ever leave it again for any length of time (over a couple of months) I'll definitely get a 100W solar kit or similar to keep all the batteries topped up. That said, does any recommend the best way to join 6 x leisure batteries? I know there is a preferred method for 4 x leisure batteries (as per Smartgauge website- Method 4: http://www.smartgauge.co.uk/batt_con.html) but what about 6 x batteries? Currently it appears the batteries are done via method 2 but with the main feeds taken from the middle battery. Hope that make sense.... Thoughts? Thanks again for all the advice, appreciated!
