Greatech Battery's Rate with the best lithium lipo4 batteries available, will buy More Only from greatech... Love Them

Given the highly rated reviews, by professional testers ( K. Gann) and online via FB and other websites. Everything i have read is extremely positive and has convinced me to purchase at least one of these batteries, even though they are on backorder, over several other big name manufacturers who have items on shelves now.

Great Deal and Good Work!
Best price to buy!
Well done!
Thanks!

Very happy with this battery and have a single battery installation as well as a 2S2P 24v configuration, multiple load tests meet or slightly exceeded the rated capacity. This battery is perfect for anything that does not exceed the 100 amp BMS rating. Multiple batteries in parallel will increase load and rating capacity. If the install will be in an environment that typically stays above freezing these are the logical choice for performance and longevity. This battery will work well with any solar charge controller with a LI / LifePo4 or customizable battery charge voltage setting and the manual is very detailed.

I am happy with these. They are simple they don't have a heater but they do have a BMS. I checked the charge and it has the amp hours it is supposed to. I only have a 300 watt system two batteries and I can power my garage and my shed and charge my tools.

Very happy with all Greatech batteries purchased so far. All batteries holding charge and will make for an excellent 4-battery bank (400Ah/5120Wh). Used NOCO GENIUSPRO25, 25-Amp charger on each battery separately and waited until I was certain each battery held a stable state-of-charge. Will now connect them in parallel. Can't say enough good things about the customer service. Easy to contact and very quick to respond. They take very good care of their customers!! Knowledgeable and professional!

I installed this in my 19ft RV connected to a 200w solar system and a 2000w invertor. So far works great, we're able to run the coffee maker, toaster and the 900w microwave in the morning. I may upgrade to 400w of solar to help speed up charging but so far it seems to be holding out really well. I've ordered a battery monitor to help manage the available power.
