I am looking to replace the diode splitter on our narrowboat with a relay. I have read up on the subject including on this forum but opinions seem to vary, leaving me unclear, so let me ask a few questions and see if a consensus emerges. 1. Does a VSR have any real advantage over an ordinary relay (seems like more to go wrong for the sake of one less wire to connect)? 2. Should the alternator output go direct to the domestic bank or to the starter battery? I can see the advantages of the former (maximise the volts where they’re most needed, minimise the current through the relay) but then why are VSRs bi-directional? 3. What size cable should be used to connect in the relay? Firms sell kits using 16 sq.mm cable and 100 amp fuses but I read that a BSS inspector failed someone’s VSR installation on the grounds that it counts as a battery-to-battery connection and so must be done with 25 sq.mm cable. 4. What happens if I have a stand-alone mains charger connected to the domestic bank and I then start the engine? Is there any risk of blowing up the relay or its associated fuses by drawing starter current through them? Assuming no damage occurs, would the two charging systems then confuse each other? For reference, the boat has a domestic bank of 3x110Ah, a 90Ah starter battery and an alternator rated at 67A.
I'm hoping to wire up my second (leisure) battery this weekend via a VSR (Voltage Sensitive Relay). I may have goofed and bought the wrong cables. Are these cables suitable to go from the first battery to the VSR and the VSR to the second battery? https://www.amazon.co.uk/gp/product/B0711V19RR/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 It describes them as: Sectional battery cable 10 mm2 made in Germany Length: 50cm (distance between the centre of one hole to another) Colour: red, very flexible, very pliable in a PVC sheathing Eyelets: 2 x M5 (provided in mm for the diameter of the eye opening) - high conductivity and dense wall thickness. Application: Battery cable for car, voltage of battery cables is 12 V, suitable for car cable clamps Just wary as the current cables to/from the main battery is a bit thicker.
Hi All Looking to install a Cyrix-ct-230A Battery Combiner (VSR) My question is .... :- I have seen many installs using just the one Alternator and Two battery banks, but non with two (I have one 70A Alternator for Starter Battery and another 70A for domestic bank) So is it possible at all. Just thinking of using my spare power from starter alernator to help keep domestics topped up in winter months :-) Thank you Andy
