Re: SLA Maintenance - Science vs BS?

Once you get into sealed, then there really isn't any reconditioning or equalizing. I have some advanced lead chargers that have a crazy high voltage setting for desulphating, but it's only for refillables, and requires monitoring the specific gravity of the fluid and replacing what boils off. With...

Re: SLA Maintenance - Science vs BS?

Sorry. Might be "old school". But trying to keep up with the "younger generation". Last time I looked at lead-acid was for stationary cells (glass cases, and "heavy"...) used to store solar electric energy. :wink: Very similar to my intended use case, plus I own 3 cars and a few other devices (unin...

SLA Maintenance - Science vs BS?

I have a few different 12v Lead Acid batteries, mostly SLA AGM but a few old school FLA with the water caps. Is there quick and simple guide to how to take care of these guys, that is based on science as opposed to marketing BS? Specifically about maintenance, reconditioning, desulfation / desulfati...

Re: ATV conversion (mostly done)

Sorry for the very very late answer, it costed about 4000€ It is now almost finished, I still have to tweak the controller to have more power at startup but that's all. Maybe create different drive profiles as I have a switch wired but is is not really necessary. The issue I had with the regen not ...

The lack of captain's outfit in the kit is a deal-breaker though. :lol:

THRIFT STORES What's worth it? Anything in particular to keep an eye out for? Yesterday I saw a Razor electric scooter for $15 but it had a SLA battery so I decided against it. I know those diabetes, err I mean mobility scooters generally run SLA too. I figured the motor and related components were ...

Safety & charging in the water?

1) What sort of charging hardware do you use to charge watercraft? Does standard automotive EVSE tick all the boxes for full safe use in something like a yacht or a houseboat, which is intended to remain in the water at all times? Or is it only good enough for things like jetskis and small boats whi...
