When our 40v 5ah Greenworks batteries are run until the bike stops, the voltage when measured on the removed battery is 0 volts. I think this verifies that the LVC is in the battery.

5/8/18 update... My wife and I have been using the Greenworks 40V 5.0 Ah Lithium-Ion batteries on our ebikes and so far, are very pleased with its performance for reserve power. It does have LVC protection built into the battery and an automatic maintenance mode when not used for a month to...

I have been using "cat ears" for 3 years and they work just great for me.

I asked Grenworks customer service if their 40v Gmax batteries had low voltage protections. Their answer... Yes the 40V GMAX batteries have a low voltage protection built into them.

We do run lights on our ebikes all the time and if we would forget to turn off the main power switch the battery could be drained down to 0 volts without some kind of LVC protection. There is also the slim chance of a short in the connectors/wires which could also drain the battery. After...

I need a bit of extra range when on longer rides. I am considering one of the following tool batteries. All are 40 volts and would give me the required extra range. The manufacturer's charger would be used. When needed, the ebikes regular battery would be unplugged and the tool battery plugged...

This spring I decided to make our two old hybrid Giant 700c bikes into ebikes. I bought 36V 260 (low) rpm front geared wheels from Ebikeling and initially powered each bike with three 12v 9ah SLA batteries in series. We wanted to see how these inexpensive SLA batteries would perform for us as we...

After reading much more about Lipo packs, I am going to take the recommendation to use a safer and simpler LiFePO4 prebuilt pack with built in BMS and supplied charger. I think a 36V 7-10 AH pack would work just fine for our limited use. A few suggestions on a good place to purchase one would be...

My wife and I are retired and go on bike rides about 15 miles long at about 10-12 mph. We just enjoy a slow ride on blacktop bike paths. Because of health problems we are both having difficulty on hills or against strong winds, we only need help in those situations. I have looked at the Hill...
