Shorai Batteries new disclaimer/requirement

"Is there any charging system for Nortons that will adequately charge the Li batteries? "

Well, as I stated earlier, the Lucas RM23 alternator or the Alton that comes as part of their E-start works fine. I just returned to the bike after 3 months and the Shorai voltage was 13.42, which is greater than a 90% charge. There was no trickle charging involved. If it can show that after 3 months, clearly the charging system was adequate. I can't argue with shorai's recommendation for 13+ vdc at idle but the reality with two years on the battery is that either of the two above systems easily maintain it. The idle on my bike is approx 900 RPM. The alton puts out a bit over 13 at that RPM; the Lucas slightly under. I ran the Lucas and the Alton each for approx half the time I have had the Shorai. Alternating those systems wasn't my plan but that's a different story,

IOW, I'm confident that the two above systems, with good wiring/connections/additional grounds (all part of normal Norton concerns) are adequate for the Shorai.

FWIW, one one occasion about a year ago I accidentally left the bike's ignition switch on all night. When I came out the next day, the Shorai would spin the starter but bogged at the compression. Batt voltage was 5.92! I figured I had destroyed my battery. But I connected a trickle charger and a few hours later, voltage was in the 13's and the batt spun the starter as normal as it has continued to do. I know I sound like an ad for Shorai but to me it's the perfect batt for the Commando.

Does your system put out 13.1 volts idling with the headlight on? The 05 Triumph Daytona with 440 watt alternator barely does this, but all of the older bikes I have here fall short of this recommended number.

It could be that Shorai builds a better Li battery than Ballistic does. The Shorai is Japanese made, the Ballistic US made. I chose the US made one for a couple of reasons, but given the high quality of most things that have come out of Japan over the last twenty years, it would not surprise if the Shorai is a better product.
They still need to fess up on true amphours tho!

Not using one on my commando (yet?), but I'm entering my second winter on K1600gtl, and so far I've been very impressed, starts bike easily at 10f, but I have to follow modified startup procedure at that temp, basically this:

Turn on ignition
Put on helmet, gloves, etc
Start bike

For whatever reason this tech requires a draw in cold weather which heats battery and increases cold cranking amps from what it was when sitting cold. Seems counter-intuitive and I cannot explain it, but I can tell you it makes significant difference in cranking

"Does your system put out 13.1 volts idling with the headlight on?"

No, neither the 3 phase lucas nor the Alton will do that. If you scroll back to the beginning of this thread you will see the specific voltages that the Lucas and the Alton produce on my bike with headlight off, on low, and hi beam. The Alton does better than the Lucas and needs about 1100 RPM to generate 13.1 with the headlight on.

But, as I said, the systems both kept the Shorai charged with no problem at all. I suppose if you routinely spent hours at idle and then shut the bike down it would be an issue but I can't imagine that scenario as normal. The Shorai ran the bike (trispark) with no problems for about 50 miles back home with no charging system when I had a charging system failure last year and still showed about 13.3V when I got home.
