Greetings everyone. In one of my earlier posts I mentioned that I might be buying Ping batteries, and now that has happened. I had the shop install the batts and I've had a couple of days testing the new ride. And... quite a big difference. The hill that I climb every work day is one that I normally take a run at- it's a steep winding slope- but the new pings will actually acellerate with little strain. I haven't taken any readings from the cycle analyst, but am planning to do so in this topic page as time goes along. Total cost, to me, was about $790 Canadian, all in. The shop had a few difficulties installing, as the shape of the duct taped unit didn't quite fit the existing box, and they had to shim the box a bit, but everything is well now. The battery weight has gone from about 60lbs to just over 20lbs, and this has made a difference in handling, reponse, speed and as mentioned, acelleration. I actually decided to buy the Pings after bionicjay reported his pings catching fire! Sounds crazy, but when Ping sent him another pack, I was impressed that he did the right thing. Happy trails everyone.

Support V is for Voltage
Overall today I rode about 37km (23mi) and used 12.5AH. It's slightly above par compared to the SLA's, but there are fairly significant differences- the bike is both more responsive with increased power and speed. I also noticed that there was little 'drag' on the last steep hill I climb, one that had I used the old batteries, would have stopped me about 3/4 of the way up. If I'm reading LifePo4 graph's properly, there is little power draw down over amp hours used. I forgot to check the voltage at the beginning and end of the ride, however I did notice that at no time did the bike draw more than 32 amps, and this included a steep 8 percent grade that took a few minutes to climb. On my next ride, I do want to do better speed checks, rather than subjective and also monitor the voltage over time. Happy trails.

Another update. Today I rode to work and back, and this time I ensured tire pressure was about 40psi (when is came out of the shop I forgot to check and it was low). And this time I had better results. There is a place where the commuter trail I ride on merges into a busy road, and at this spot I often note the amp hours used. Until today the best I'd ever seen was .990ah- and today it was .916ah, a marked improvement. Also a gps speed test showed almost 36km/hr on a stretch of road that I would normally travel at 32km/hr with SLA's. So overall it's there's about a 10% difference in speed and amp hours used. Happy trails, will post with new data soon- I'm sure people are as curious as myself as to how well the batts perform.

Today I went for a ride along the galloping goose communter trail that winds its way through Victoria BC and points beyond. I'd taken this trail before, but the difference this time was seeing more pavement than gravel. I rode 38km and used 12ah of battery juice. This was a combination of economy/speed range and I would say the trail is mostly flat with sections of winding path and hills. So for maximum range, I guess 38/12 x 20 (20ah max) = 63km or about 40 miles. Of course, realistically, I would push it much beyond 90% of battery capacity. This is a slight increase in distance compared to the SLA's but again, speed has also been increase by about 10%, so overall a gain of between 10-15% in speed/ah combination. On this map of the trail, I basically went from near downtown to Langford and back, http://www.gallopinggoosetrail.com/maps/east.html . Happy trails everyone

Time for another update, and no news is good news. I do notice that I travel about 45km on one charge, however the speed is faster, and I do take a route that involves more hills. On level ground, with the SLA's I'd go 32km/hr while with the Pings I travel between 35 and 36 km/hr. I'm very happy with the batteries, so far so good. Happy trails everyone.

Greetings everyone. Well it's spring on the West coast, although it's probably the coldest spring in 14 year- hail today. I didn't ride, but the batteries are performing well and yes, I do get 45km real world for 20 ah's. No problems, just wanted to check in. I did send Ping an email letting him know the batts are doing well, but other than that- it's still fun to ride whenever I can. Happy trails everyone.

Greetings everyone. Just an update to let everyone know that the batteries are going strong, and although we had a miserable spring and early summer, we've had a sunny and warm late summer/early fall. I've been driving many kilometres- hopefully I've got another six months left. In the past I've always replaced my SLA's in about a year, so I hope for two with the Lithium's. Happy trails everyone.

I have a pair of Ping batteries from - I forget how many years ago - that are still going strong.
