  1. Hello George, Here's a link to the data sheet on the LiFeBlue Battery website: http://www.lifebluebattery.com/ewExternalFiles/LB12200-HCLT Data Sheet.pdf The low temperature battery was introduced about 1-1/2 years ago. It is the same as our standard 200AH except it has the heater circuit. The latest version, and the one that OTT uses, is model LB12200D-LT. This version has an RS-485 data port built in for programming and future use. We have been selling our batteries for about 4 years now. Our OEM is Shenzhen Topband Battery Co. and they design and manufacturer our cells and cu
  2. Hi NCeagle, If your generator can produce 15 Amps AC (assuming you meant this), then you can easily power the Xantrex charger for the needed amperage. I think the gap is insignificant unless you are only relying on PV solar power. 340 Watts of PV solar power in ideal conditions (high irradiance, low angle of incidence, cool cell temp) can make over 20 Amps.
  3. OK. Here's a fact from our business over many years: No customers has ever told us that they could not use the credit because the alternator or generator or shore power also charge the batteries. Customers wrote to thank us for the ITC info. They had never heard of it. They all used the full amount for the credit and were grateful for the $ thousands saved. I understand your wanting to research so I hope this is helpful.
  4. 1. RE @NCeagle's concerns about prolonged charging at 100%, I know that Battleborn batteries have a higher capacity than labeled and that their BMS is supposed to keep their batteries within a range that will prolong their life. Do you use a similar tactic or should owners be cautious about charging your batteries to 100% or depleting them to 0? I did notice that you recommend that owners deplete their batteries to 50% if being stored for longer than 30 days, whereas Battleborn recommends charging them to 100% before disconnecting. 2. Is your BMS software upgradable via your app? Are
  5. That is correct. Up to 10A per battery will bypass the heater circuit. That means with PV solar power, you can be charging in early morning, not wasting the power. If current rises above the threshold, the battery will stop charging and turn on the heater circuit. Each battery requires 12 Amps to turn on the heater. If your PV solar can not produce enough current, the battery heater timer will start. You are also correct, there may be a period where the battery heater will not be on but the current is too high to charge the cells. This is another reason I recommend installing the auxiliar
  6. Hi Overland, The LB12200D-LT requires 12 Amps DC to turn on the heater circuit. If sufficient current is not available, a 10 minute delay timer will start. Note that low current from your PV solar system will charge the battery at any temperature down to -4°F. The BMS firmware can be updated by us (in our service center) via the RS485 data port on the top of the battery. Here's a teaser: We are currently developing a Comm box with WIFI to connect our battery to an internet connected router. You will be able to monitor your battery from anywhere using our new App. And, it will se
  7. The language in the ITC law is the credit may be taken for all the PV solar power system components installed in any "dwelling unit". There are no conditions on how long you live in the unit or whether all of your energy is made by the energy system for which the credit was granted. In other word, the entire system with labor cost receives the credit.
  8. Hi Overland, As mentioned in another response, our battery does not need 120Vac to operate the heater. Any sufficient current 12 volts source will work.
  9. Hi Overland, A few corrections are needed. 1) There are many studies that have been done establishing the fact that storing any Li-ion battery at 100% SoC will cause faster degradation by corroding the positive plate. This will shorten cycle life. One study has shown that storing at 100% SoC AND keeping in high temperature will rapidly decrease capacity. Therefore we recommend keeping the battery as cool as posible and long term storage at 40%-50% SoC. 2) LiFeBlue Battery does not need to be removed to be stored if temperatures are above100°F. However, as stated above, cycle lif
  10. Hello AndrewK, This is true. It is the internal temperature that matters. Just using the battery provides some internal heating that helps replace heat loss with cold ambient temperatures.
  11. Hi Susan, Just FYI, we (Starlight Solar Power Systems) have designed and installed over 3000 RV solar power systems since 2001. Customer always claim the entire amount of parts and labor using the ITC. This includes batteries because a battery is a necessary part of the system.
  12. Hello Overland, Your statement is incorrect. LiFeBlue Battery has a very broad operating temperature range of -4°F to 140°F. Cell over temperature protection turns on at 149°F. With the LB12200D-LT (sold by OTT) you can charge and discharge within this range. The batteries can withstand -40°F but should not be stored below -4°F.
  13. Excellent Fritz. You make my point well for why I highly recommend installing the TV auxilliary charge circuit. It eliminates the need for a generator.
  14. One important note: some of the batteries mentioned in this thread do not have low temperature protection.
  15. Hello Fritz, Statement 1 above is incorrect. With our latest BMS, if the cell temperature drops below about 26°F, the heater circuit will activate whenever you apply charge current. If the current is below 0.05C , charge current will be delivered to the cells. If above 0.05C but less than the minimum required for the heater, the battery will not charge and a 10 minute delay timer will start. When sufficient current is available, the heater will activate. When the release temperature threshold is met, current will be directed to the cells. The charge source can be anything that make 1
