Yes, but they did not eat up power like the bike light did.

I need to rewrite the data so that it easier to read. I going to have lunch first then work on it.

What a morning! Sunny with a gentle breeze, 2 hours later rainy and windy. I was able to get a 8 mile bike ride in bebore it started to rain. The bike felt easier to pedal at power level one, than the last time I rode the bike at level 1. Below is today's data and 6/23/2021. Both sets of data...

I have not tried the battery yet. Yesterday was breezy (gusts up to 25m/h). Today was suppose to be rainy and breezy, but it is sunny. So I will test the battery today. @PCeBiker-You are more than welcome.

@ HarryS- I did take a ride, about 25 miles. I saw a bird of prey flying with something in its mouth. I took the battery off the charger after 8 hours (4:30), it was still at 54.4/≈53. So tomorrow I will take it for a ride.

Okay, it is about 12:00 AM. Here are my readings with the time. please remember the battery was/is on the charger 9:00 ≈50v Analog 9:30 51.9 (digital) ≈51 (analog) 10:10 53.6 or 7 ≈52 (analog) 11:50 54.4 (digital) ≈53 (analog) At this time the light on the charger was green. The...

Good Morning, The ebike battery stopped charging my lights last night. The battery's capacity according to the multimeter was 3.2 volts. I didn't trust the reading so I used the meterto measure other batteries that that I owned. This morning I retested the battery, it was still at 3.2 v. I put...

Thank you, HarryS and PCeBiker.

They are called "1S ~ 24S lithium battery pack single cell voltage tester" and you can get them online from Amazon and AliExpress. A local source might be RC hobbyist store. Both online stores have more than one model for purchase. AliExpress...

@ PCeBiker- Thanks for all of your assistance. It is greatly appreciated.

Yes, that is the video. The person at Indy RC was able to find a contection for a 13S, for the battery charger. I don't have the instrument to read the individual cells, the balance charger, nor the connector. I am looking at roughly about 1/2 for the cost of the battery to purchase those items...

Update- On 12/2/2023 Went to Indy RC store showed them the Youtube video about balancing an ebike battery, the sales person (who is also a RC hobbyist) said it should work. On my way home I stopped at EZ Bike Rental to ask what they do for batteries that need balancing. EZ Reantals were closed...

12/01/2023 Update I recharged the battery yesterday. Leaving it on the charger longer than needed. Using a multimeter its capacity was 54.5 volts. While on the charger its capacity was 55.6 volts. Today I took it to Batteries Plus. They were not able to help me. Tomorrow I am going to the...

11/29/2023 Update- When checking out why the bike chain was skipping/jumping off the front sprocket/chainring there were three issues; 1) worn front sprocket/chainring, 2) a bent outer plate on the chain, and 3) a chain that needed more oil. I am working on these issues. Sprocket/chainring is on...

LOL Yeah, I could use tonight to check, clean and re-oil the chain and front sprocket. I would rather ride in the winter sun, than work on my bike. I took my other bike for a 20 mile ride. The battery did go down 0.2 v during my ride. 😂

I started my ride and went about .6 miles and my chain started to jump off the front sprocket. So I will be running a bike light off the battery through the USB port. The battery on the bike light is very low. I will report after I get some results. Now I need to work on the front sprocket of...

Thank you, PCeBiker. I will try what you suggested. I report to the threat after I drain the battery, by riding, and then continue draining the battery with the 5 volt light. This will occur tomorrow, because it is raining in Indy.

Thank you, Tom@WashDC and harryS.

What does your battery charge up to in volts? 54? Yes, 54.3 volts.

Hello, I hope everyone is having a good day. I have a 2014 Raleigh Tekoa. In 2019 replaced the original battery with a Unit Pack Power 48V13AH battery. I installed a 200A voltmeter on the bike when the battery was replaced. When I first purchased the battery, it would be drained at 40 volts. I...
