[Rhodes22-list] Charging trolling motor batteries underway

[Michael D. Weisner]

Please be very careful with Li-ion batteries. They do not charge the same way as lead acid cells. The output of the outboard may not be well regulated. It may damage the battery or cause a fire.Mikes/v Wind Lass ('91)Nissequogue River, NY

However, a while back I stumbled on a YouTube video from a guy suggesting that you could just directly connect lithium and lead-acid batteries: https://www.youtube.com/watch?v=tAuPfgZgXecPlease let us know what you decide and how it works out.—Peter> On 2023-06-22, at 07:28:47 EDT, Jeff Smith Photo wrote:>> I’m going to be using a trolling motor on my inflatable for a cruise where I > will not have access to AC for charging.
