These suplies are 17.00 and can handle 38 Amps max load on the 12v rails (dual). This makes a perfect parallel charging power source for 3S configuration and can handle 12S2P or 3P packs at their 1C charge rate (5A) with no problem.

bearing wrote:I have a question which is a bit off topic, but may be of general interest. I'm thinking about buying 24 6s 5Ah Turnigy packs for an electric motorcycle build. The weight of 24 packs is too high for air shipping, it has to be split into 10 kg groups. 11 packs is 10 kg, so the pack would have to be split into three groups. Shipping will be about 20% of the battery value. Since custom fees (and I think also taxes) in my country are based on the total value including shipping, in the end shipping cost will add an an even bigger amount to the total. So, shipping is a cost I would like to reduce.
Have anyone of you had Hobbycity ship heavier stuff than their air mail limit, or got a shipping in a cheaper way?
