    Daly BMS Active balance coming now!

    I notice that the Smart BMS app i use with my Daly 120A BMS bought about a year ago, now includes an Active Balance feature (presumably from an update). Does anyone know the recommended current settings for this (with a nominally 280Ah 12.8v battery)? Thanks - Nigel

    Renogy DCC30S and LiFePO4 battery charge

    Arbee: I've noticed this a bit late and I don't know whether I'm missing something here, but 13.4V is the absolute maximum voltage you can get from a 12V LifePO battery (4 cells) once it has charged fully and charging has stopped. You will only see a higher voltage while it is connected to a...

    charging lithium batteries with high amp marine alternator

    Hi Loyalist I'm with you on keeping it simple! You might like to look at the other thread "Hybrid Battery Bank?" where we have discussed the possibilities of connecting an Li battery/bank in parallel with an existing SLA setup. This solves some of the charging problems but you probably also...

    Hybrid Battery Bank?

    Well the SLA bank is total 345Ah and I'm thinking of maybe a 120Ah lifepo4 so that may be ok as you say, but anyway, I think the next step when I go back to the boat in a couple of weeks' time, is to check out the exact specification of the alternator and if necessary, enquire with the...

    Hybrid Battery Bank?

    I certainly agree about avoiding the drop in batteries, I would much rather follow Will's advice about building your own and bring able to control the BMS setup. As for the rest of it, I shall certainly need to think some more!

    Hybrid Battery Bank?

    That's a very good point, it could put people off using lithium batteries completely if they knew they also had to have a new alternator or an extra $400 (at least) charge controller! But some companies do seem to sell LiFePO batteries as "drop in replacements" for lead acid on boats, don't...

    Hybrid Battery Bank?

    Hi Danny Thanks for that, your video is very interesting. I also found quite a bit of helpful information for a canal boat setup on the Canalworld forum, e.g. https://www.canalworld.net/forums/index.php?/topic/99667-another-lithium-battery-thread/page/9/...

    Hybrid Battery Bank?

    I presently have three sealed Exide 115Ah 12v lead acid batteries paralleled in the battery bank of my canal boat which are charged by the engine alternator (70A) and 300w of solar panels with an MPPT controller. I could do with a bit more battery capacity so I wonder if it would be possible to...

    LiFePO4 heating pad for cold temperatures

    Here in the UK there are some specialist electrical engineering suppliers such as RS-online who have some interesting products that might be suitable and presumably are also available elsewhere e.g...

    charging lithium batteries with high amp marine alternator

    Here in the UK quite a few people with narrowboats on the canals use lithium battery banks and the boat engines usually have alternators in the 50-150A range. It's worth looking at "Jono"'s Youtube channel e.g where he discussed the installation of his batteries - although be warned, he's gone...
