Battleborne Lifepo4 are made in the US. I just got some batteries from another company in China that shipped in late January, so they were still shipping at that time. About $3k for 13 kwh worth with a BMS. The Tesla option is quite a bit cheaper but since they are pure lithium I don't know if I would want them on a boat. I think the Leaf is NIMH.

Hello everyone,
Over 10 years ago, you guys helped me to convert my 24' pontoon to
electric. I ended up with a Torqeedo Cruise 4, four group 31 AGM
batteries and a 4 channel DualPro charger. I've had ten great summers
using this configuration on some inland lakes in Ohio. Last summer, I
started noticing the battery capacity wasn't what it was when the
batteries were new. The Torqeedo would shut down due to "depleted
batteries", but I was always able to turn it off and then back on where
upon I could return home at a slower pace. That is one of the things I
like about electric vs gasoline. I have never been stranded.
Anyway, I suppose it is time to replace the batteries. I can't complain
about getting 10 years out of them. As I see it, I have two options:
1. Buy another set of AGMs - a little under $1000
2. Buy LiFePo4's - at least double the cost, but less weight and more
usable range.
As an engineer, I like using new technologies so I lean toward the
LiFePo4's. However, many of the posters I follow on this forum bought
them directly from Chinese suppliers. With all the COVID 19 disruptions
to business and our government threatening to raise tariffs, I worry
about placing an order that never gets filled.
I would appreciate any opinions on which way to go and any
recommendations for low risk suppliers for batteries.
Thanks,
Pat
