are sealed lead acid batteries lighter, and made for scooter

[mntjohnson]

I think sealed lead acid (SLA) batteries have less fluid, so are lighter than normal marine battery, is this right? So it would be much heavier to replace SLA with some marine batteries??

Are SLA batteries crafted to be drained yet still have good power and rechargeability, so are they crafted like marine batteries? It seems strange SLA batteries don't say "low drain" or something to indicate they are good for scooters, wheelchairs, etc. I know B&B battery maker makes some special scooter batteries, seeming to show the SLA batteries at Battery Plus store is a general battery not a suited-for-scooter battery.

Forget SLAs man! lipo will do the same job in 1/4th of the space with 1/4th the weight or less, and produce higher voltages and have a longer lifespan for only twice the cost. Don't waste your time or money with buying new SLA.

SLA batteries are glorified lead acid batteries. The only thing they offer over standard lead batteries are they do not require refilling and they can be installed on the side. All other problems relating to lead are the same. SAL is no more powerful, lighter of anything else you can think of. The acid is simply a pasty putty instead of a liquid.

Go lifepo4 if your a newbie or lipo if you have more advanced.

EAT the cost for Lipo LifePO4, even NiMH. get away from lead unless you are in the Po' house and building something from scraps.
If you buy a bike that comes with lead use it while you save $ for LFP.

Couldn't agree more. However sometimes budgets don't have $300-$600 for a decent battery.

But if you have any credit, get the lifepo4, it's much cheaper per mile in the long run. Figuring optomisticly, say you spend $200 on 3 good 12 ah sla's and get 200 cycles before they degrade to the point you can't use them. You have at most 10 miles range and perhaps 2000 miles lifespan.

Buy a $600 pingbattery, 36v 20 ah, and you have 30 mile range times 1000 cycles. 30,000 miles? Ok, cut that in half and you still have 5 times the lifespan for three times the money. not bad. And you get to have a bike that is 20 pounds lighter.

If you must go with lead, then scavenge em somewhere, or at least buy ones designed for ev use. Trolling motors don't pull amps like a bike does, so they aren't what you want really.
