12V And 24V Lithium Batteries
12V 150Ah LiFePO4 Deep Cycle Battery
150Ah in a 330 x 172 x 215 mm case at 14.2 kg, with a 150A smart BMS and Bluetooth monitoring.
Product Overview
150Ah in a 330 x 172 x 215 mm case at 14.2 kg, with a 150A smart BMS and Bluetooth monitoring. It sits between the 100Ah and 200Ah packs for installations where the extra 50Ah matters but the larger case will not fit, and it is a common choice for solar, RV, marine and trolling motor work. Published 3000+ cycles and 95-100% usable depth of discharge.
Key benefits
Why Buyers Choose This Pack
Half A Step Up From 100Ah
50% more energy in a case only slightly larger than a group 31, which frequently solves a marginal sizing problem.
150A BMS Matched To The Pack
Current rating scaled to the capacity, so the pack can deliver what its energy suggests.
14.2 kg
A comfortable one-person lift, which matters when the battery lives in an awkward locker.
Bluetooth Status
Real state of charge on a phone rather than an interpretation of a flat voltage curve.
Application scenarios
Where It Is Used
- RV and caravan house banks
- Trolling motors and marine electronics
- Solar systems on a 12V bus
- Off-grid monitoring and telemetry installations
- Mobile workshop and service vehicle power
- Backup supply for small critical loads
Who it is for
The Buyers This Pack Suits
Installers With Tight Lockers
Where 200Ah will not fit but 100Ah is not enough.
Anglers And Small-Boat Owners
Running a trolling motor plus electronics for a full day.
Distributors
Filling the gap in the range that customers ask for most often.
Problems it solves
What It Fixes
Sizing Gaps In A Range
Jumping from 100Ah to 200Ah overshoots many installations. 150Ah lands where the requirement actually is.
Voltage Sag Under Motor Load
LiFePO4 holds voltage nearly flat to the end of discharge, so the motor does not fade through the day.
Guessing At Remaining Capacity
Bluetooth monitoring makes the decision to head back a data point rather than a hunch.

Packing and documents
How It Ships And What Comes With It
Packing And Shipping
Packing follows UN38.3 requirements for lithium battery transport, and the carton and pallet arrangement is confirmed with the quotation for your quantity and destination. We do not publish a fixed carton specification here because it changes with order size and freight mode.
Documentation
UN38.3 and the MSDS travel with every lithium shipment, and the certificates listed in the specification table above are supplied for the model you order. Tell us the destination market at the quotation stage so the document set is planned rather than chased after the goods are built. Where a certificate we do not hold is required, we will say so rather than promise it.
Manufacturing
This pack is built at Shenzhen Sike Power Technology Co., Ltd. in Da Peng New District, Shenzhen, with cell grading, assembly, BMS integration, aging test and final inspection carried out in house. Only brand-new grade A LiFePO4 cells and a top-brand smart BMS go into it.

Installation guide
Getting It Right First Time
Step 1
Measure against 330 x 172 x 215 mm, close to a group 31 footprint but slightly different.
Step 2
Check the motor or inverter peak against the 150A BMS rating.
Step 3
Charge with a LiFePO4 profile; charge time is published at 3-5 hours on a suitable charger.
Step 4
Mount clear of standing water - IP65 is dust tight and jet resistant, not submersible.
Step 5
Use the Bluetooth monitor to confirm the charger's end-of-charge behaviour at commissioning.

FAQ
12V 150Ah LiFePO4 Deep Cycle Battery Questions
Will it fit a group 31 tray?
The case is 330 x 172 x 215 mm, close to group 31 but not identical. Measure the tray, including any strap or lip, before ordering.
How long will it run a trolling motor?
It depends on thrust and throttle. Send the motor model and the hours you want and we will work through the arithmetic.
How fast does it charge?
3-5 hours on a charger capable of the current, per the published figure.
Can I connect two in parallel?
Yes, with matched packs at a similar state of charge. Fuse each pack separately.
Is Bluetooth included?
Bluetooth real-time status is published for this pack. Confirm it on your order and it will be on the specification sheet.
Which certificates apply?
MSDS, UN38.3, CE, ROHS and UL.
