For those pilots who feel comfortable using third party batteries, Powerextra might be a good alternative. I only use DJI OEM batteries because Ive had battery inconsistency errors when using third party batteries a long time ago, and had to send the batteries back.
DJI is pretty good at battery warranty claims. I got 1 DOA battery on a refurbed P4P I bought, and it took them 28 days, but they sent me a new one.Good to know, esp re: low cycle used batteries. I've been keeping my eyes open on this forum and DJI's support forum for any reports about DJI rejecting warranty claims.
