Is there any active 48V BMS for 300A or even more?

HelloEven though I'm working already quite some time on the conversion to electric I still would have the possibility to choose a different BMS. I do have a 123 Smart-BMS ( https://123electric.de/gb/ ) here which is waiting for installation but for two reasons I would be interested to switch to an active system:First I don't have a lot of place above the battery (10-12cm max) and the 123SmartBMS boards are mounted on top of each cell - so for me they…See More

Battery charge - discharge voltage?

HelloA question for the battery experts. I have about 320Ah@48V of Winston cells installed.https://en.winston-battery.com/static/upload/file/20220507/1651883606747444.pdfWhen I bought the cells (last year) Winston specified the "maximal charge voltage" as 4V. Interestingly now they are writing 3,8V.But every video or blog from people building their Winston batteries they are talking about 3,65V…See More

Trolling Motor for a 27 foot sail boat

Hey everyone,Excited to have joined! Currently my Yanmar 1GM10 is probably dead and eventually I'd like to install about 7kwh of batteries hooked up to a 5kw BLDC motor. But it'll take at least a few months to get everything here from China and then I have to install it.I was wondering if anyone had experience pushing their sailboat with a trolling motor? I have a Cascade 27 foot sailing boat (6500 lbs) I have two AGM batteries that seem fine and I am thinking either a 40ish pound thrust 12v…See More

Volvo SD120S sail drive electric conversion

Hi all,In my research, I have read a number of posts about DIY and manufacturers coupling eletric motors to Yanmar sail drives, but little info about connection to Volvo sail drives. I have a 35ft/10.7m cat (displacement 16.5K lbs/7.5t), purchased new in 2002, with 2 x Volvo MD2030 diesels (max RPM 3600), MS25S gearbox (2.47:1), SD120S and 3-blade folding props (17x12 pitch).I understand the efficiency of direct connections, however apart from replacing the whole engine system with a $60K+…See More
