These Batteries are WAY Cheaper than Lead Acid /AGM batteries
How can we say that? Under average working conditions, you get about 30 Ah out of Lead Acid / AGM 100 Ah before you need to charge it! So for each charge, you need about 3 Lead Acid batteries to do the work of 1 of these. But you also need to consider how long the battery will last... The average Lead Acid / AGM Battery is good for 500 cycles. These will last over 2500 Cycles under similar conditions. Over it's lifetime, you need about 15 Lead Acid batteries to do the work of 1 of these.
Brand New, A Grade Cells from a Quality Approved Manufacturer
CALB China Aviation Lithium Battery Co Ltd have specialized in the manufacture of high quality Lithium batteries since 2007.
Established in 2007
CE, UL, TUV & RoHS approved
IATF 16949:2016 approved
IATF 16949:2016 is the International Standard for Automotive Quality Management Systems.
Prismatics Cells make building larger battery systems easy
So much simpler...
Larger cells require less wiring and connections
Easily grouped and connected with high current bolt on busbars
Less cells to manage with a battery management system
Simpler fault finding
Easily add more cells to increase the stored energy of the system
How many and what size cells suit me?
100 Ah cells are for smaller spaces and lower capacity requirements.
4 x 3.2V x 100 Ah cells in series give a Nominal 12.8 V, 1280 Wh pack
Vastly Superior to prepackaged 12V enclosed batteries with onboard BMS
With Prepackaged battery packs...
If one internal component in your whole battery fails... Chuck it out and buy a new one!
Many manufacturers don't tell you what cells they use inside the pack. How good are they?
They also don't say much about the BMS - battery management system. How good is it?
They do not cool as easily - be careful using them in hot conditions
Most of them are current limited - they cannot be configured to allow engine starting
When building Prismatic Cell packs
You get to choose the quality of the cells and the BMS
You also get to configure the system to have more control over current limits, charging limits and temperature cutoff points.
Air Cooling can be simply achieved. For example using cheap computer fans.
There will be more wires to connect - but it's not rocket science!
If one component fails - it can be replaced
