How do you plan on charging the batteries while driving? We have two 48V ebike batteries that charge via a 400 watt Modified Square Wave inverter, using the provided 120vac bike chargers. Depending upon discharged level, that can take a few hours. Do you know the amps/wattage required for charging your batteries and time to charge?
We have two 48v, 750 watt Bafang mid-drive conversions. Most people want speed. Our mostly off-road hilly, narrow trail riding needs slow speeds and torque. It took a while to get front and rear gearing to get gear 1, mode 1 down to about 5mph. What wattage is yours? Looks like an absolute torque/wheelie monster/chain/spoke breaker/wheel spinner. Even geared down, ours can exceed 20 mph with a six speed rear. We really like the mid-drive vs hub. Is yours torque sensing?
My biggest fear was chain breakage. I still carry a chain, breaker, master links and repair parts, but after 800 miles have never used. One flat from a small thorn caused tube liner installation along with slime type tubes. A throttle is nice in case of becoming unable to pedal.
Our asses run down long before the batteries do. There has always been enough battery after riding to run the DC fridge overnight that draws about 3.5 amps when running. My display shows state of charge that helps determine remaining power before removing the battery.
Based upon rruff's review, I now own Elefast/feence lifepo4's that can take a high amp fast charge. I now reserve the bike batteries for just riding.
The amazing thing about an ebike is how much further away from the campsite we can become lost. Another plus is now mine is a physical therapy machine after a hip replacement. Also old and broken.
I used Anderson connectors to connect to the voltage reducers and to connect the reducers to 12v loads.
Your plan sounds like a plan.
