HI guys, finally i decided to build my very first eboard, after 3 months of lurking into this awesome community. Yeah. i did my homework, so many things to learn. Parts are on the way, well most of them. Here is the list
-Board: Never Summer El Jefe (inspired by @scrant ) (on the way) -Mechanical: TB single motor kit: trucks, wheels, motor mount, belt … (on the way) -Electronic:
1. VESC from Enertion.(ordered) 2. Enertion R-spec big boy 6372 190kv.(ordered) 3. Space cell pro 4 (10s4p)(initially). 4. Controller: Nyko kama(maybe upgrade later due to some reported dropouts)
The battery is a tricky part. Due to aviation regulation, they don’t ship to where i live(Vietnam). So I am back to old school: DIY. I have 3 options and some questions in mind, PLEASE help me with this one.
1. Li-on 12s4p Samsung 25R with BMS. 2. Li-on 10s5p Samsung 25R with BMS. 3. 2x6s 12000mah lipo to make 12s battery(or 2x5s makes 10s). Tear it down, make it slimmer.
Of course, the battery will have with a meter. Questions:
With spec like that, should my board go with 10s or 12s? There are a lot of posts saying 12s is a bit too much for the VESC, that it will burn drv chip but there are also many boards use 12s with no problem ex: @longhairedboy , @lowGuido …
Can lipo battery use BMS? I ask this because I saw noone here doing it. How can i charge the battery? I mean with what voltage? According to what i learnt : if 10s then 42v 2a, if 12s then 50.4 2a (4a for fast charger) Is this correct? Are there any cheaper alternative?
How can I choose amp(current) for BMS ?
All help and suggestion are appreciated. Pic will coming soon.
