Hi all,

For my electric trike I had been using Lead Acid 48V 100Ah batteries which I now intend to replace with Lithium ion. I have two manufacturers near my place that have this type of batteries in stock:

Would this battery be able to deliver a better performance than the lead acid batteries. The manufacturer of this battery has said not to discharge for than 1.2C. Are they being overly cautious with this number? I thought Lithium ions would allow for a higher discharge rate. Is it OK if I have a discharge rate of say 2-3C for 4-5 seconds at best?

Looking forward to replies.
Thanks.

Why not look for battery packs from wrecked hybrid cars there is shit
loads of them on ebay.

https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR0.TRC0.A0.H0.XKia+Optima+Hybrid+Battery+Pack.TRS1&_nkw=Kia+Optima+Hybrid+Battery+Pack&_sacat=0

These Kia Optima packs have 9 30volt batts in a pack. Price about 300 bucks on ebay.
A little cutting on a band saw or saws all and can retain all the mountings. I have four packs
in my truck right now will put four more packs in the back box.

Kinda wanna use new batteries that can be bought again and again. And for a 48V system, around 60 - 100 Ah preferably.
