justcallmenuel: I am sorry house. I noticed that over the past years there has been a wide variability in the prices of deep cycle batteries unlike in the past when the prices were somewhat close. For instance I see 12V, 200mAH batteries go for between 80k to as high as 180k each. What then guides people's informed choices on these batteries? Why are some so cheap and others over 100% above the cost of others? |

alstacs: Durability and quality bro. Let me share a personal experience with you.At some point in 2019April (precisely)I bought 2 units of 200ah AGM battery at Alaba for 72k each while the reputable Indian brands were going for 120k each. The battery lasted only 9 months.You can't compare a Quanta battery of 150k each with a battery of 85k.Good value comes at a premium!! Although another school of thought will insist the 85k China batteries will serve you well if hooked up with panels but I haven't verified that sha!!! 1 Like |

What you said is not truly correct using price to compare the quality of battery, the fact is most importer sometime import different brand and print another name on them, very ram pared that how they make profit, the only way to manage your battery is how you used it, Yes, you charge and discharge, each process is called a cycle and every battery has times of cycle which is the real life time of that battery So buy battery with high number of cycle, but you will never see it on the battery spec or on the battery due to Nigeria fraud way of doing business NiyiOmoIyunade: 2 Likes |

TBrownAuto: It is true the price is not only the indicator to the quality of a product, but over time premium products are usually costlier than their non premium counterpart. It is now left to the discretion of the buyer if they are willing to part with more for the perceived quality of the product. It's like walking on a tightrope, you need the pole (your common sense) to achieve the equilibrium while watching out for that rogue gust of wind (overpriced goods) that may knock you off the rope. ![]() As per knowing the number of cycles, do you really blame the people importing it (Nigerians) or the people producing it (Chinese) for this lack of information? Often times, stuffs such as this is hidden by the manufacturer, the buyer on the other hand does not really care as the batteries are pretty cheap. After all most marketing decision always comes down to the cost of the product. Of course no marketer will want you to know the cheap battery you just bought has only 250 cycles, but they can always tell you that it is 70k each for 200ah ![]() 2 Likes |

mctfopt: One very easy way to be deceived into overpaying for goods (battery inclusive) is to equate high price with quality. Even in international markets where big brands are involved, many have come to realize that a large part of the cost you pay for big brands goes into the branding racketeering. Nokia android phones are a good example. Those phones are not made by Nokia, they are made by HMD Global who make returns to Nokia per unit sold. So, when you buy a nokia phone, a little part of your cost price goes to paying for the label on the phone. On the other hand, buying goods solely on price is a very good way of ending with a dud. If it is extremely cheap, that is often for a reason; fake product, under-specification (150AH labelled as 200AH), use of poor quality components, poor after-sale services etc. So, price should be the least of your consideration when buying batteries. 1. Physically inspect the battery; poor attention to manufacturing details is often obvious even from the packaging. Poor external appearance often signposts poor internal quality. 2. Track records; ask people who have used a product before about their experience. While some people will be lucky or unlucky, if you get a fairly consistent report about a battery, you should take those reports seriously. 3. Traceable to a known manufacturer. People put their labels on product as a way of establishing brand recognition and dominance. Companies with consistent poor reports will soon disappear. Be aware that many unscrupulous businessmen can put any label on any product, 4. After sale services. Even best companies have occasional failures and problematic production batches. Do they stand by their products with good warranty supports? I will buy a weak local product with warranty compared to a strong brand with no one to talk to when problem arises. 5. Finally, people say, you should buy battery based on weight as the components are fairly standard in the same product group. If a 200AH AGM battery weighs less than 150AH from a good brand, you are probably buying poor quality or fake product. However, this comes with a caveat as some dubious manufacturers have been known to add glass or rock to a compartment in their battery to add dead weight. These are better things to consider rather buying the one asking for more money. But like others have pointed out, the treatment of your batteries is probably the best indicator of how long it will last you. Consistent over-discharge or overcharging of any battery will make it die young. 7 Likes 1 Share |

This whole quality/premium vs price discussion. What I have found is that in a free market with informed participants, good quality and higher price generally go together. The market soon learns to avoid a low quality product with high prices and continue to pay a premium for a good quality or top grade product. You may succeed foisting a falsely rated or falsely branded el-cheapo product on people for a while but ultimately the market feedback mechanism will weed out such a product when it fails to stand the test of time. I classify products firmly in the premium, value and mass market (disposable) segment. In today's market, I do not know a battery with same real life performance as Quanta ( I rate the battery a decent value offering and not premium) that sells for 60% of the Quanta price except self imports or deals come up. Same way Victrons and MustPowers cannot be compared in the things they do - a premium product will always attract higher prices vs the value or low budget offering all things being equal. That said, pricing alone is not the criteria to know a premium product by - feedback from previous buyers/users, verified datasheets and field performance data as well as being knowledgable about that specific niche the product plays in so that you can match the correct product to the correct application all go a long way. 3 Likes 1 Share |

Re: Solar Energy, A Complement To FTA by ceaser: 4:31am On Aug 03, 2020 |
mctfopt: This is really good. I think one can find a way to integrate it in each room. Currently the plan is to have only one point USB charging socket installed in each room. The socket is AC-powered but only has USB socket output. |
Re: Solar Energy, A Complement To FTA by mctfopt: 4:33am On Aug 03, 2020 |
NiyiOmoIyunade: I can attempt to answer this, most that transitioned to LFP use may be using inverter not adequately suited for charging LFP. An external charger may just be what they might need. |
Re: Solar Energy, A Complement To FTA by ceaser: 5:02am On Aug 03, 2020 |
NiyiOmoIyunade: Yes sir. Using my experience as an instance. I recently gave out a 12v system (the BTS inverter that I retired). Stuff was installed indoors with some ventilation of course, and the user being someone with acute sense of smell complained that the battery produces some odour whenever it charges, more pronounced with mains charging. I believed right away, and had to provide 12v LFP replacement. Now instead of the battery to charge to 14v cc-cv with the in-built inverter charger it stays at 13.6v float voltage especially when it has initially sensed a 14.1v SoC in the LFP. 12v LFP needs a constant 14.2v driven in until charging source is removed, and not the 14v boost, 13.6v float voltage algorithm programmed in that inverter. I had to eventually reluctantly include one of my extra 12v LFP chargers in the giveaway. By the way, I also have 12.7v Li-ion AC chargers (for 12v 18/65/0s battery pack) for sale, for anyone interested. They are all new, unused but have been tested. Pictures later. |

Re: Solar Energy, A Complement To FTA by ojeysky(m): 8:04am On Aug 03, 2020 |
NiyiOmoIyunade: There is no major reason for that unless the inbuilt charger is not doing as much amps as required. So if my bank is 400AH and my inbuilt charger can only do 30A, adding an external one to support will be helpful to the battery. The other reason I can think of is for certain lithium BMS that does not wake up with solar charging when they trip due to cut off voltage. An external charger will be required to jumpstart the BMS so the inverter can come alive. Edit: I see this has been dealt with |
