I like the bottle, but you could just as easily carry a pack that small in a handlebar bag, or whatever.
Yeah, Lord knows I'm not adverse to small bags, but it's just both of my MTB frames have all that space between the frt. down tube and the tire. And the lugs were already there.
Lipo is also a cheap way to make a big increase in your pack size....
And it's getting less expensive all the time. These little bricks were on sale for $15.98 ea., so $64 for the pack(it's so small, I'm not sure I can even call it that). I think the sale price was almost half off.
Right after I bought them, HK shut down their site 24 hr.s to revamp it. There are no more "sales" on batteries or discount pop-ups, But, it seems most of the batteries have had their prices cut by 20%. The Turnigy 6S/5000mAh, 20C's that I used to use before the Multistars went down from $50 ea. to $40.
I'm really liking the Multistars. Some one here summed them up by saying; "They have traded off dis-charge capacity for lightness and sm. size." And it's true. But on these little packs I am seeing some sag, more than the Turnigy 20C's even. I don't think my little aux. bottle would be very useful on a powerful bike.
I don't enjoy dealing with the lipo charging and monitoring constantly, so I prefer the bms packs for most of the riding I do.
Well, I'm single, retired and don't have any dogs
and fussing over my ebike and the LiPoly is my only hobby(sad but true).
My there is something satisfying about holding something so compact yet powerful in your hand(Maybe that's how my Ex felt when changing her AA batteries
And after years and many balance chargers, I've got the charging routine down pretty good w/ a Mean Well HGL and my coveted Blue Battery Medics.
Even so, I just bought this little item for 12V charging in the boonies;
I'm only getting 110 Watts on my 12.6V server supply, but what attracted me to it(aside from it's ridiculously small form factor, is a feature called ; "High power, high current, high-performance power conversion circuit." Basicly, one can reverse the load and the 12V power source, use the LiPoly to recharge the truck battery, in theory anyhow. Haven't tried that out yet.
