Hard to believe the price but if it works then we will all be going down that route.
I'll try it another year first before i commit to an opinion i think.
At that price and length of service, it's earned its due already.
Hows your Lucas Supreme going ?
Again I ordered a Numax and this Lucas Supreme arrived. I held onto it as it listed the identical specs and battery weight as the Numax did. It looked as though it was from the same battery supplier but I was never 100% sure. It was at the time of the Covid aftermath that stock was difficult to get hold of, so you took what was given. (I actually put in the notes to Tanya that they weren't to supply any other battery as a replacement if they didn't have stock with my mobile number, but they ignored that. They have a black mark from me for doing what they did.)
This Lucas lasted the usual 3 years for us. The battery would have survived a little longer when it just ran our 2 pumps, but as soon as it was asked to run the diesel heater it ran out of capacity and died by midday. That was even starting the diesel heater on the way to the first job, so the alternator supplied the power for the initial start-up. It was also in winter, so it's the time when most batteries fail. Batteries were always charged every night with Numax smart charger.
A replacement Numax was £110 at the time when this lithium was £329 plus £49 for the 230v charger.
I hesitantly replaced that battery with my Fogstar LifeP04 battery. Reluctantly because of all the bad publicity Lithium-ion has. I decided that if the battery caught fire and my van burnt to the ground, I would be forced into retirement as there is no money left in the kitty for a replacement van.
This lithium battery is now 1 1/2 years old and is working perfectly. Just yesterday it was at 40% state of charge at the start of the day, and I decided we needed hot water after we started work. (40% as I now switch the b2b charger off to use the battery's capacity before recharging to full using the alternator.) No issue starting and powering the heater as well as the pumps. 5 miles home after the day's work and the battery is at 50%. This is the first time in 20 years I haven't had to focus on daily battery charging.
Yes, I expect to have to top up the charge occasionally during winter, but that isn't an issue as I put a heater in the van every night anyway.
Would I go back to a lead acid leisure battery? I very much doubt it. I'm guessing that by the time this battery is scrap, some other battery source will be available which I probably won't be around to see.
