Thanks for the insights. I am up and running. Next thing is tree removal.
bcrosby wrote on Michael B Caro's profile.
Michael, I understand you are putting together group buys of LiPOFe4 cells. I'm not particular about brand but want quality cells. Approximately 280 AH cells would be good. I might be interested in as many as 24 cells. Please let me know what's possible. Zipcode 83833. I promise I'll be a great customer! Ben

@Michael B Caro did your daughter check the Kehengs? Are there 16 that are matched and undented?
I can see the light!
jimcalf wrote on Jenny Wu's profile.
Hi Jenny,
Can you please send me current pricing for 16 300/280/230ah cells. Trying to decide which to buy. Also JBD 100 & 150 8s BMS pricing. Will consider shipping from china if the price is better. I plan to order very soon. You can DM me.
Thanks!
