High amperage lithium battery packs seem to be readily available now in 24, 36, and 48v.
I'm looking for a 12v one, with a capacity of 30ah
I'm theorizing that it should weigh and cost about the same as a 36v 10ah pack, with BMS and charger, but with the cells connected more in parallel than series ?
Does anyone know where I could get one with that spec, either Lipo or Lithium Ion ?
My interest is twofold. One would be to occasionally supplement my 36v 10ah lithium bike batteries to give 48v.
The other main reason though, would be to power my 12v mini electric outboard on my kayak. I currently use a pair of 12v 14ah SLA batteries in a bag wired in parallel, to give 28ah, though that ends up as about 15ah because of the 50% discharge cycle.
It strikes me that the big lithium advantage with ebike technology would be just as useful with the kayak motor. Lighter, longer cycle life, and a full 30ah instead of 15ah.
Of course, compared with padding, it is "cheating" !!
