MJCM Posted August 31, 2022 Share Posted August 31, 2022 Found this Battery pack online. 48V 100Ah for 3566 THB. https://www.lazada.co.th//products/i3988883446-s15462117258.html I would get 4 or 6 and I could power a great deal of the house with it. Too good to be true for this price? 2 Link to comment Share on other sites More sharing options...

From this topic So if 60% only that would mean 60Ah, for that price it still isn't that BAD ???? Link to comment Share on other sites More sharing options...

Edit: 1 question though, where then comes the 100Ah from. Their calculator broken? ???? Edited August 31, 2022 by MJCM Link to comment Share on other sites More sharing options...

I reckon they're using pretty naff 2.5Ah 18650s. Pack is 3P13S so I divided 100Ah by 39 cells giving 2.56Ah per cell. In reality 3 x 2.5Ah in parallel gives 7.5Ah which is the real capacity. 1 Link to comment Share on other sites More sharing options...

So to get 100Ah, you would need 100Ah/7.5Ah = 13 Packs. Correct? And 13 * 3566 = 46358 THB ???? As usual: if it sounds too be good to be true then it usually is (<- Strikes again) Edited August 31, 2022 by MJCM 1 Link to comment Share on other sites More sharing options...
BritManToo Posted August 31, 2022 Share Posted August 31, 2022 Even 13 packs couldn't fix this scam as you need 14 x 3.7v cells to make a standard 48v pack and these muppets only use 13. 1 1 Link to comment Share on other sites More sharing options...
KhunLA Posted August 31, 2022 Share Posted August 31, 2022 Ebike batteries are notorious 'mislabelled' My 48v30Ah battery is 1/3 the size of my 48v10Ah battery, which goes 3X as far, at lease. And only cost 2X more. shy of 6k baht vs 3000 I was not surprise or really expected it to meet the posted specs. I was enough for my needs, as only need about 15-20kms a day, 1 Link to comment Share on other sites More sharing options...
sezze Posted August 31, 2022 Share Posted August 31, 2022 It's like amps or speakers , 10000 watt pmpo , don't even try to get more then 10 watt out (or in) them , as it would fry . or the newest additions https://www.lazada.co.th/products/aldiesled-900000w-10000m-i3014497971-s11087847135.html https://www.lazada.co.th/products/bonya-179v-3-li-ion-2-32-i3625989049.html?spm=a2o4m.searchlistcategory.list.15.44f32a7fYs8bJY The list goes on and on and on ... They just add a few numbers nothing even remotely related to a real value . Just think about stuff and check out what is possible and what not ( and stay away from high numbers , as they always are fake ( unless priced similar )) 1 Link to comment Share on other sites More sharing options...
