    Aventon Level 500w Upgrade to 1000W or Higher?

    Hello community! I am about to purchase an Aventon Level after months of research on the best bike for the price. I have a perhaps silly question, but could I swap the 500W stock for a higher grade, say 1000W or even higher? That being said, will the bike frame, motor etc be able to handle...

    Battery vibrates loss.

    I have only had my M2S All Terrain Sport R750 Integrated for a month now. Yesterday, the battery vibrated out of the cartage, and I was just riding it in the road. Yes there were bumps and rough road, BUT that is totally unacceptable. Just imaging riding this MTB on a trail. I didn't just...

    Is there any difference in voltage between two 48v batteries with different Ah?

    I've been searching for a chart that converts battery voltage into a percentage, and have found some for 48v. But it doesn't show what Ah the chart is for. So I'm wondering if there's any difference in voltage between two 48v batteries that have different Ah? I have a Yonglin 80c display where...

    Can I Trust DLG Batteries?

    I've been researching several ebike manufacturers (e.g. Amigo, NCM) who use batteries assembled by DLG in China. I've read the best battery cells are produced by Samsung, LG, and Panasonic. I've also heard DLG uses cells from Samsung and Panasonic; however, I'm not certain I can trust that...

    Recharging Monster Sized Batteries

    With my old ebike, the 36V/12Ah battery needed a recharge cycle after every commute, that isn't the situation with the CCX's 52V/19.2Ah battery. While I liked the idea of removing the smaller-lighter battery and recharging in an indoor environment, a 13pound monster battery pack seems happy with...

    Cold Weather Biking and Batteries...

    One thing I hate about winter and e-biking is the cold. I commute every day back and forth to work for a total of about 12 miles a day. Although it does not snow in South Louisiana often but it does get down into the teens and 20's fairly often throughout the winter. Another thing about...

    Samsung 30q Batteries, BMS and Vruzend Kits - Atlanta Georgia

    I bought a couple Vruzend kits and attempted to make my own battery. Not sure if the BMS is faulty or if I just have no idea what I'm doing (probably the latter) but somehow I killed 7 of the batteries. I tested the others (21) and they are all around 3.4v so the rest seem fine. If you want...

    96v 300ah battery pack anyone?

    Hello So I'm going to duck down a bit, I'm actually doing a car conversion BUT before you move on, my question relates to e-bike batteries. I've seen e-bike battery packs for sale which are 48v 59ah with built in BMS. Could these be connected together in s2p2 format to give me 96v and 100ah...

    Need suggestions for a Sondors dual battery conversion.

    Hey everyone, I was wondering if you could suggest some guidance for wiring two batteries onto one Sondors fat bike? I have a running bike, and I can mount a small spare battery anywhere. However I am weak on wiring, and I don't want to set the bike on fire. Anyone done this before...

    Battery Upgrades

    Upgrading batteries for ebikes a possibly complicated question, so I'm going to separate it... My objective on my ebike project isn't power or speed, but distance, without overpowering the motor or having to purchase one or two EXTRA batteries. I want to get a 350w hub kit, but the...
