ManAdii: Are you gonna diy this or get an installer?. I feel you would need an installer, so to make it easier for every body..get quotes from your installer and post here, together with your avg load and how many hours you would be running it 1 Like |

mctfopt: Please help me find the link on AliExpress And quite me with it, also those ones you upload, are they for sale? |
Re: Solar Energy, A Complement To FTA by mctfopt: 7:12pm On Mar 05, 2022 |
Moneyboyz: Not for sale. That's the one I used for my upgrade. Unfortunately, I didn't buy on AliExpress as it is costly, see example here: https://a.aliexpress.com/_mMJdMvO I bought at Alibaba and shipped via sea (waited for 110 days) 2 Likes

The DIY route is sooo tempting but I dey fear small So I just got a a couple of 5kwh blue carbon batteries for my 3kva system. I'm in need of an additional 30kwh battery for my 5KVA (yet to be installed) system. Apart from the falsly labelled Felicity and Blue Carbon batteries, what other options are there locally that is tried and trusted with verified capacity? Plyontech batteries are sooo expensive. I'll be spending over 5m to achieve 48v 300ah |

MontyNG: There is really no major issue with DIY I think you may find it easier than you imagined. However if you still prefer packaged there is the Jos guy that does packaged bank, you may check previous pages for his contact |

mctfopt:How much did you get these? |

@earthrealm can I chat you up via WhatsApp? |

Moneyboyz:I think the best battery for ebike or any electric vehicle is 18650 lithium batteries. Even telsa uses it because it has higher energy capacity. 480 pieces of 2.6ah of 18650 should give you 59.2v normal voltage and 67.2 at full charge. Which is about 4617.6wh or 4.6kwh. If you were in Abuja I would have source for the battery and make one for you. 5 Likes |

mctfopt: That's the problem I have with AliExpress, the shipping fee alone is more than the product. Will see if I can get it from Alibaba. |
Re: Solar Energy, A Complement To FTA by Dishtech(m): 11:52pm On Mar 05, 2022 |
This is 5.12kwh, 24v but can be configured to any voltage. 1 Like

Dishtech: Tesla doesn't use the run of the mill type of 18650, he's forever tweaking the batteries Tesla uses. Tesla did this when it introduced the 2170 cell with the Model 3 and Powerwall. This cylinder was 21 millimeters by 70 millimeters rather than the 18 by 65 dimensions of the 18650 cell. The lithium ion batteries you mentioned has a higher energy density thus more compact but since the type is probably lithium ion it has a shorter cycle life (500 to 1000 cycles against 2500 to 3500 cycles of lifepo4) . The only disadvantage I see with running with lifepo4 prismatic cells is just bigger size and weight. Remember as lithium ion discharges, the voltage drops which leads to the ebike running slower, but with lifepo4 prismatic cells, you have the full voltage till almost the battery cut off, so the ebike motor is almost seeing that peak voltage and thus outputs higher performance. Also I charge my lifepo4 prismatic cell ebike battery at half the time I charge my lithium ion battery. FYI: I've used both lithium ion and lifepo4 on an ebike, the difference is super clear. 1 Like |

ManAdii: That was last year, I think I got each cell then @ $7 each. |

ojeysky: Thanks... Yeah, I've been in touch with the jos guy. Once I have a cash for the 30kwh, I'll consider him along with going the DIY route |

Re: Solar Energy, A Complement To FTA by Valto(m): 2:50pm On Mar 06, 2022 |
Barezzi:me sef, am interested. the ones listed on alibaba are confusing too. i need a basic one, maybe mctfoct should share the type he have. |
Re: Solar Energy, A Complement To FTA by ManAdii: 3:38pm On Mar 06, 2022 |
Dishtech:Is this lithium or lifepo4? How much does I cost to make this? |
Re: Solar Energy, A Complement To FTA by mctfopt: 4:34pm On Mar 06, 2022 |
Barezzi: Many sellers on Jiji. But I bought in China. |
Re: Solar Energy, A Complement To FTA by mctfopt: 4:48pm On Mar 06, 2022 |
Valto: Just check for the following 1) Motor size/type ...go for Bafang motor back hub drive ...not really a fan of mid drive motors 2) Battery size...anything above 10AH is good @ 48V 3) Shock type ...Mozo shock rocks 4) Tire size (with time I noticed 26*3.0 tire has the best grip for both offroad and city riding). The four inch tire looks cool especially when riding sandy paths, but sucks when doing city riding Also ensure it has Pedal Assist as well as a throttle (if you wanna go lazy and go full electric). Digital displays are awesome. If it's gear type look out for Shimano for that smooth shifting. I also love my ebike to have a rear carrier...Bought one without one, a pain when you want to carry some stuff . Had to correct that mistake in my next purchase. 3 Likes 2 Shares

Hello My People ! As i read more and more into the LifeP04 world, i realize the need to have certain equipment and tools around to help you diagnose and generally service your equipment better. One of these tools is a good LifeP04 charger. Since this is a DIY commnuity and many individuals will coupling their packs together, it is good to have a good charger so that you can top balance your batteries before coupling the BMS together. You can then use a multi-meter to verify the voltage. This is good for users who don't have solar to charge their batteries and their inverters are NOT able to charge LifeP04 cells directly. So, let's say you have a 12v LUMINOUS NRGT TUBULAR BATTERY 220AH and you want to chill with the big bois and join the LifeP04 geng. You purchase 4 EVE 280AH LiFePO4 (LFP) 3.2V Cells Battery which is equivalent to 12v. Ideally, you will need to top balance these cells (as they come at 45% capacity) before slapping on a BMS. So, i came across a recommended charger by this guy on Youtube https://youtu.be/P2yKVMoaGsU and found its listing on AliExpress for nairalanders https://www.aliexpress.com/item/4000465060713.html?spm=a2g0s.8937460.0.0.7e332e0eGhorcc. I think its a good equipment to have especially for those with a large battery bank as it can charge consistently at 40Amps. It also comes with a software that you can install on a pc to monitor your charging. 2 Likes

mctfopt: Nice looking bike. I am currently in the market to get some bikes and had gone to Simba to check out some of the ones they had on offer. Never knew that the ebike revolution had reached here. My interest has been piqued. Would appreciate any links to resources or guides to purchase one. Thanks

mctfopt:Telsa uses 21700 battery which is a modification of 18650 to have higher energy density and reduce weight. LiFePO4 has a larger size though has higher cycle life but reduces efficiency due to total weight of the vehicle. All battery voltage drop on usage, the voltage drop is dependant on load current and battery AH or capacity. 1 Like |

Solar gurus in the house, is this inverter below a good buy? I'm to this and I want to go through the diy route? I need your urgent reviews. Can it charge lithium batteries? Thanks

Re: Solar Energy, A Complement To FTA by samir101ng(m): 6:59pm On Mar 06, 2022 |
ManAdii: @bigrovar is the resident expert on the ipowerplus inverters. He's been rocking his for over 5yrs now i think. So, i think they are okay. I don't know whether they can charge LifeP04 batteries though without some tinkering with the firmware. Just make sure sha that you are buying an original product with warranty. |
Re: Solar Energy, A Complement To FTA by chymer(m): 7:59pm On Mar 06, 2022 |
mctfopt: I need link to the Alibaba store, including your forwarder. I will greatly appreciate it sir. |
Re: Solar Energy, A Complement To FTA by mctfopt: 8:14pm On Mar 06, 2022 |
Dishtech: Every RE person knows that battery voltage drops with use. There is a difference between the way liFePO4 battery and lithium ion polymer cell voltage drops during usage. You may just have to use the two to understand and see for yourself. |
Re: Solar Energy, A Complement To FTA by mctfopt: 8:21pm On Mar 06, 2022 |
chymer: My bro, just google the ebike specs you need and chat up the seller as my seller no longer has the ebike I bought in stock. You can ask any question either via PM or here to help you make a decision. I used this old forwarder then Nonikings. https://www.nairaland.com/1819824/newly-found-shipping-agent-china#24807137 You can chat up the Chinese number that ends in 2441 for more updates on rates, and ETA. Most ebike size won't be more than 0.5CBM DISCLAIMER: I'm not affiliated with them, any business transaction you do with em is solely based on your decision to proceed or not. 2 Likes |
