Thanks, will the delta q stock charger work well with the 80v system? Is there a bms that you would recommend? (Unless it comes with the batteries). Also, I’m used to 150Ah flooded batteries. How does the less capacity but more efficient lithiums compare? Sorry for all the questions, just trying to figure this out.
Lithiums have a 2-1 advantage overall. 60ah is on the light side, but good for 15-20 miles at 25mph level ground.
Charger may work as it is. Try it. If not it can be programmed for lithium.
No bms is needed in most cases. Try it without first.
Thanks Dave, just a few more questions. Will my stock charger charge the 80v system enough to fully charge the lithium or would it be better to get the 72v batteries. Also, do you know shipping costs to zip 30269? (Just south of Atlanta). Thanks a bunch,
Hi Dave, I’m still very interested in your batteries, i’ve been out of town the last 3 days. Please don’t take this as an insult, but are there any protections for me as the buyer when buying something outside of eBay? For instance, if the batteries were lost in shipping or for whatever reason did not show up. Thanks for your understanding, just trying too figure it out.
Ok thanks, I would like the batteries. I can send you the money and would appreciate if you could handle shipping as well. Also, are the batteries new and balanced? Thanks, if you can send me the total bill I’ll send it your way. Thanks!
Hi Dave, I’m on the road again this week but wanted to stay in touch. I’ve been talking with the wife and she has concerns about the range we would have with 60ah batteries. We live in a hilly city and round trip where she typically goes is about 13 miles. We are a family of 4 and usually have some sort of groceries/cargo. My old 155ah batteries would be almost depleted on the round trip. I don’t want to have “range anxiety”. What do you think? Would 60ah work?
Thanks Dave, the Bolt module sounds perfect but it is more than I want to spend. Sorry if it feels like I’m dragging my feet on this, I just want to get what works for us. I may just have to keep with the lead acids for now. Do you know how many miles were put on the Bolt pack? New lead batteries are about 1000$, I’m willing to double that for lithiums provided I can get the same range. (About 15-20 miles or so). I’m guessing 80Ah lithium would be the minimum for my needs. Unless you wanted to come down on the Bolt pack, I’ll probably just stick with my leads for a while. Thanks for all you help!
Thanks for the info, I’m still deciding on which route to do. What programmer is kinghappy referring too? Also, I saw some blue cells (80ah) that might give me the range I need. Anyone tried the blue cells? Thanks
Thanks, what does it mean when the battery data says 1c or 2c? Are they talking about internal cells within the battery? I’m familiar with much of electronic lingo but the battery lingo is unfamiliar. 25s? Is that 25 batteries? thanks for the info!
