That would be massive! Ive always been a huge advocate for huge batteries. I plan to run always start them off fully charged. If i wait until my board dies before plugging in then there will be a massive rush of current and i think ill fry a lot of components or damage my cells.
I do think it would be cool to wire it to my board so i can charge it at the same time but I want to be able to use this while camping or day trips when i dont have my board so I think that it having its on BMS maybe the better option for me personally.
Have you taken in consideration the amount of energy that you will lose by converting the energy back and forth. You could instead just charge directly from the pack instead. Only thing you wold need is a voltage regulator and a current limiter.
Yea I have. Ive found that the inverters that can operate with an input of 48v and output of 12-v ac are well over $150. i found one on amazon for about $110…
Do you have any links of items that you would suggest for this build
Let me make myself more clear. The board will be taking power directly from the battery backpack. The only thing that will need to be stepped down is the inverter which will be used for anything else. It may be used for charging the boosted boards in my group ride but mostly for camping and such
Long cables are pretty bad story for VESC usually (surges in cables under load can occur easily) and potentially sources of bugs. Often read “keep your cables as short as possible”.
Was thinking of series that can’t be connected with different capacity packs. So in parallel it’s okay to run different capacity like 12s7p and 12s11p together?
You have 12s7p in a type 500 case? I can probably do that for additional 2p but I’m already predicting 40-80mile range on urethane depending on riding style for some epic trips on bike paths.
This is something I have thought many times about. But like the others have said, the weight is much more comfortable in the actual board. A small trailer with batteries would be the better option.
Who the hell is gonna pull a trailer. And when you wanna stop at the store for a Coke are you gonna drag your trailer inside? Not saying it’s a bad idea, but definitely not the best option…
How about a small backpack with wheels? They actually already make them. I’ve seen this guy cruising with a fat subwoofer on a trailer. It just makes more sense then having that weight on your body when you’re trying to be maneuverable. And what if you fall onto your highly explosive battery pack?
Wouldnt the battery on the board with short power wires act as a capacitor and dampen surges from the back pack?
How much will this back pack weigh? Ive carried a 20lb backpack while riding and, to be honest it really wasnt fun. The weight wore me down pretty quick.
What is the whr/mile comsumption on your 4wd so far?
