this is new, never saw such device except Mpt7210A being used widely by westerners and sourced from china. And I would choose the mpt7201a as it has display and can store charging requirement into temporary memory and that display is very useful (mostly after being electrocuted today haha) and...

here's the amperage around 11am while it's slightly cloudy. Highest i got was 9.83A

I just got electrocuted with 80v 1A damn! that's painful. burned my fingeri tried to clip this alligator clip on comverter output turned out it sparked as my thumb is slightly wet. lucky me i'm wearing rubber slipper and manage to pull my hand, fuck still burning now haha

indeed lesson learnt haha Anyway, ditching the booster, will instead use MPT 7210A Just ordered from Ali Express :) I accidentally touched the Alligator clip which located closely to each terminals And wear rubber slipper And only 1 hand is electrocuted, the other hand is isolated

Hi Svetz Sorry for gone missing for a while Upon checking with the battery manufacturer, the battery indeed has BMS in the blue packet. The charger is just giving constant Voltage and Amp to charge the battery (Converting AC to DC) So, having said that the 'third party' here is the main brain...

Hi, I just discovered that my multi-meter fuse blew off. Hahah Upon short circuiting the panel using another multimeter, I get around 10A-11A when I faced both panel towards the sun. Just get myself a new Ammeter today and will try again tomorrow (it's midnight now in Malaysia)

No problem, I'm cool with the efforts and all replies in here. Much appreciated. Keep in touch and I will keep on sharing my finding from my project :)

this is my battery pack photo (attached) and this is probably the same spec of battery sold in alibaba. A rear battery. So is it true it has integrated over charge controller? I have opened the casing just now but I cant see anything under the blue plastic as the battery already glue (photo...

This is the charger label . And what comes into my suprise is, my 100w panel output only 0.45A even when the intensity of sun is high and positioned directly to the sun. Do you think anything wrong with my panel? I connect both 100w in series. it should come out at least 3-5A before boosted

Hi, I was wondering if i put my setup this way 2 x 100w mono panel in parallel Connected to DC-DC Boost converter to output 24v DC (with constant voltage output) Then directly supplying my 24v 500w DC-AC inverter without battery to run my electric bike charger adaptor which is 240v This...

this is my dc-dc boost converter

I guess, the best bet is to add another 100W panel and connect all in series and ditch this 100W X 2 parallel arangement. Means making it 18V X 3 without the use of converter. So hopefully when I stop and setup the panel I can get 54V 4A or 5A when all are in series. 1A is too slow to charge my...

Alright, so let say i take out the inverter and directly connect the Lithium Ion battery pack to the DC booster, does the battery pack of my e-bike knows when to cut off the charging input? I'm worried if the DC booster will somehow over charged the battery. How does an ebike battery works...

i have tried taking the reading of the battery on full charge and it is shown as 50V at my multimeter. So, would you say that the battery will never over charge if i set my dc-dc boost converter output voltage to 55v constant? And yes, I am only using 100w x 2 mono panels in parallel because...
